Due to a wrong assumption concerning the behavior + directly after the start of the timer/counter the function + sam_oneshot_cancel(…) calculates the wrong remaining time. The code + assumes that the counter register is zero directly after the start of + the timer, but this is not true. To start the time/counter a software + trigger is invoked, this trigger starts the timer/count and sets the + counter register to zero, but the reset of the counter register is not + performed instantly. According to the datasheet: "The counter can be + reset by a trigger. In this case, the counter value passes to zero on + the next valid edge of the selected clock." Thus the counter is set to + zero between 0 and USEC_PER_TICK microseconds after the clock was + started. + In my fix I use the freerun count value to determine if at least one + tick passed since the start of the timer and thus if the value of the + oneshot counter is correct. I also tried to use the function + up_timer_gettime(…) to achieve this but, at least if compiled with no + optimization the problem vanishes without using the value of the + function, the function call takes too long. + Another problem treated in the fix is that if the oneshot timer/counter + is canceled, we only know the remaining time with a precision of + USEC_PER_TICK microseconds. This means the calculated remaining time + is between 0 and USEC_PER_TICK microseconds too long. To fix this I + subtract one tick if the calculated remaining time is greater than one + tick and otherwise set the remaining time to zero. By doing so the + measured times are much more precise as without it.

This function can + control the delay between the assertion of the ChipSelect and the + first bit, between the last bit and the de-assertion of the + ChipSelect and between two ChipSelects.

But before + its retransmission starts, NuttX is correctly issuing next TCP + packets, with sequence numbers increasing properly. When the + retransmission of previously lost packet finally succeeds, tcp_input + receives the accumulated ACK value, which acknowledges also the + packets sent in the meantime (i.e. between unsuccessful sending of + lost packet and its proper retransmission). However, variable unackseq + is still set to conn->isn + conn->sent, which is truth only if no + further packets transmission occurred in the meantime. Because of + incorrect (in such specific case) unackseq value, few lines further + condition if (ackseq <= unackseq)is not met, and, as a result, we + are going to reset label.

    6.4 SYSLOG

    + +

    6.4.1 SYSLOG Interfaces

    +

    6.4.1.1 Standard SYSLOG Interfaces

    + + The NuttX SYSLOG is an architecture for getting debug and status + information from the system. The syslogging interfaces are defined in the + header file include/syslog.h. The primary interface to SYSLOG sub-system + is the function syslog() and, to a lesser extent, its companion vsyslog(): + +

    6.4.1.2 syslog() and vsyslog()

    +

    Function Prototypes:

    +
      +#include <syslog.h>
+int syslog(int priority, FAR const IPTR char *format, ...);
+int vsyslog(int priority, FAR const IPTR char *src, va_list ap);
+
    +

    Description: + syslog() generates a log message. The priority argument is formed by ORing the facility and the level values (see include/syslog.h). The remaining arguments are a format, as in printf() and any arguments to the format. +

    +

    + The NuttX implementation does not support any special formatting characters beyond those supported by printf(). +

    +

    + The function vsyslog() performs the same task as syslog() with the difference that it takes a set of arguments which have been obtained using the stdarg variable argument list macros. +

    + +

    6.4.1.3 setlogmask()

    +

    + The additional setlogmask() interface can use use to filter SYSLOG output: +

    +

    Function Prototype:

    +
      +#include <syslog.h>
+int setlogmask(int mask);
+
    +

    Description: + The setlogmask() function sets the logmask and returns the previous mask. If the mask argument is zerio, the current logmask is not modified. +

    +

    + The SYSLOG priorities are: LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR, LOG_WARNING, LOG_NOTICE, LOG_INFO, and LOG_DEBUG. The bit corresponding to a priority p is LOG_MASK(p); LOG_UPTO(p) provides the mask of all priorities in the above list up to and including p. +

    +

    + Per OpenGroup.org "If the maskpri argument is 0, the current log mask is not modified." In this implementation, the value zero is permitted in order to disable all SYSLOG levels. +

    +

    + REVISIT: Per POSIX the SYSLOG mask should be a per-process value but in NuttX, the scope of the mask is dependent on the nature of the build: +

    +
      + +
    • +

      + Flat Build: There is one, global SYSLOG mask that controls all output. +

      • +
    • +

      + Protected Build: There are two SYSLOG masks. One within the kernel that controls only kernel output. And one in user-space that controls only user SYSLOG output. +

      • +
    • +

      + Kernel Build: The kernel build is compliant with the POSIX requirement: There will be one mask for for each user process, controlling the SYSLOG output only form that process. There will be a separate mask accessable only in the kernel code to control kernel SYSLOG output. +

    +

    + The above are all standard interfaces as defined at OpenGroup.org. Those interfaces are available for use by application software. The remaining interfaces discussed in this section are non-standard, OS-internal interfaces. +

    + +

    6.4.1.4 Debug Interfaces

    +

    + In NuttX, syslog output is really synonymous to debug output and, herefore, the debugging interface macros defined in the header file + include/debug.h are also syslogging interfaces. Those macros are simply wrappers around syslog(). The debugging interfaces differ from the syslog interfaces in that: +

    +
      + +
    • +

      + They do not take a priority parameter; the priority is inherent in the + debug macro name. +

      • +
    • +

      + They decorate the output stream with information such as the file name +

      • +
    • +

      + They can each be disabled via configuration options. +

      • +
    +

    + Each debug macro has a base name that represents the priority and a prefix that represents the sub-system. Each macro is individually initialized by both priority and sub-system. For example, uerr() is the macro used for error level messages from the USB subsystem and is enabled with CONFIG_DEBUG_USB_ERROR. +

    +

    + The base debug macro names, their priority, and configuration variable are summarized below: +

    +
      + +
    • +

      + info(). The info() macro is the lowest priority (LOG_INFO) and is intended to provide general information about the flow of program execution so that you can get an overview of the behavior of the program. info() is often very chatty and voluminous and usually more information than you may want to see. The info() macro is controlled via CONFIG_DEBUG_subsystem_INFO +

      • +
    • +

      + warn(). The warn() macro has medium priority (LOG_WARN) and is controlled by CONFIG_DEBUG_subsystem_WARN. The warn() is intended to + note exceptional or unexpected conditions that meigh be potential + errors or, perhaps, minor errors that easily recovered. +

      • +
    • +

      + err(). This is a high priority debug macro (LOG_ERROR) and controlled by CONFIG_DEBUG_subsystem_ERROR. The err() is reserved to indicate important error conditions. +

      • +
    • +

      + alert(). The highest priority debug macro (LOG_EMERG) and is controlled by CONFIG_DEBUG_ALERT. The alert() macro is reserved for use solely by assertion and crash handling logic. It also differs from the other macros in that it cannot be enabled or disabled per subsystem. +

      • +
    + +

    6.4.2 SYSLOG Channels

    +

    6.4.2.1 SYSLOG Channel Interfaces

    +

    + In the NuttX SYSLOG implementation, the underlying device logic the supports the SYSLOG output is referred to as a SYSLOG channel. Each SYSLOG channel is represented by an interface defined in include/nuttx/syslog/syslog.h: +

    +
      +    /* This structure provides the interface to a SYSLOG device */
+
+    typedef CODE int (*syslog_putc_t)(int ch);
+    typedef CODE int (*syslog_flush_t)(void);
+
+    struct syslog_channel_s
+    {
+      /* I/O redirection methods */
+
+      syslog_putc_t sc_putc;    /* Normal buffered output */
+      syslog_putc_t sc_force;   /* Low-level output for interrupt handlers */
+      syslog_flush_t sc_flush;  /* Flush buffered output (on crash) */
+
+      /* Implementation specific logic may follow */
+    };
+
    +

    + The channel interface is instantiated by calling syslog_channel(): +

    + +

    6.4.2.1 syslog_channel()

    +

    Function Prototype:

    +
      +#include <nuttx/syslog/syslog.h>
+int syslog_channel(FAR const struct syslog_channel_s *channel);
+
    +

    Description: + Configure the SYSLOG function to use the provided channel to generate SYSLOG output. +

    +

    + syslog_channel() is a non-standard, internal OS interface and is not available to applications. It may be called numerous times as necessary to change channel interfaces. + By default, all system log output goes to console (/dev/console). +

    +

    Input Parmeters: +

      +
    • +

      + channel: Describes the interface to the channel to be used. +

      • +
    +

    Returned Value: +

      +

      + Zero (OK)is returned on success. A negated errno value is returned on any failure. +

      +
    + +

    6.4.2.2 SYSLOG Channel Initialization

    +

    + The initial, default SYSLOG channel is established with statically initialized global variables so that some level of SYSLOG output may be available immediately upon reset. This initialized data is in the file drivers/syslog/syslog_channel.c. The initial SYSLOG capability is determined by the selected SYSLOG channel: +

    +
      +
    • +

      + In-Memory Buffer (RAMLOG). Full SYSLOG capability as available at reset. +

      • +
    • +

      + Serial Console. If the serial implementation provides the low-level character output function up_putc(), then that low level serial output is available as soon as the serial device has been configured. +

      • +
    • +

      + For all other SYSLOG channels, all SYSLOG output goes to the bit- + bucket until the SYSLOG channel device has been initialized. +

      • +
    +

    + The syslog channel device is initialized when the bring-up logic calls syslog_initialize(): +

    + +

    6.4.2.3 syslog_initialize()

    +

    Function Prototype:

    +
      +#include <nuttx/syslog/syslog.h>
+#ifndef CONFIG_ARCH_SYSLOG
+int syslog_initialize(enum syslog_init_e phase);
+#else
+#  define syslog_initialize(phase)
+#endif
+
    +

    Description: + One power up, the SYSLOG facility is non-existent or limited to very low-level output. This function is called later in the initialization sequence after full driver support has been initialized. It installs the configured SYSLOG drivers and enables full SYSLOG capability. +

    +

    + This function performs these basic operations: +

    +
      +
    • +

      + Initialize the SYSLOG device +

      • +
    • +

      + Call syslog_channel() to begin using that device. +

      • +
    • +

      + If CONFIG_ARCH_SYSLOG is selected, then the architecture-specific logic will provide its own SYSLOG device initialize which must include as a minimum a call to syslog_channel() to use the device. +

      • +
    +

    Input Parameters: +

      +
    • +

      + phase: One of {SYSLOG_INIT_EARLY, SYSLOG_INIT_LATE} +

      • +
    +

    Returned Value: + Zero (OK) is returned on success; a negated errno value is returned on any failure. +

    +

    + Different types of SYSLOG devices have different OS initialization + requirements. Some are available immediately at reset, some are available + after some basic OS initialization, and some only after OS is fully + initialized. In order to satisfy these different initialization + requirements, syslog_initialize() is called twice from the boot-up logic: +

    +
      +
    • +

      + syslog_initialize() is called from the architecture-specific up_initialize() function as some as basic hardware resources have been initialized: Timers, interrupts, etc. In this case, syslog_initialize() is called with the argument SYSLOG_INIT_EARLY. +

      • +
    • +

      + syslog_initialize() is called again from os_start() when the full OS initialization has completed, just before the application main entry point is spawned. In this case, syslog_initialize() is called with the argument SYSLOG_INIT_LATE. +

      • +
    +

    + There are other types of SYSLOG channel devices that may require even further initialization. For example, the file SYSLOG channel (described below) cannot be initialized until the necessary file systems have been mounted. +

    + +

    6.4.2.3 Interrupt Level SYSLOG Output

    +

    + As a general statement, SYSLOG output only supports //normal// output from NuttX tasks. However, for debugging purposes, it is also useful to get SYSLOG output from interrupt level logic. In an embedded system, that is often where the most critical operations are performed. +

    +

    + There are three conditions under which SYSLOG output generated from interrupt level processing can a included the SYSLOG output stream: +

    +
      +
    1. +

      Low-Level Serial Output. + If you are using a SYSLOG console channel (CONFIG_SYSLOG_CONSOLE) with a serial console (CONFIG_SYSLOG_SERIAL_CONSOLE) and if the underlying architecture supports the low-level up_putc() interface(CONFIG_ARCH_LOWPUTC), then the SYLOG logic will direct the output to up_putc() which is capable of generating the serial output within the context of an interrupt handler. +

      +

      + There are a few issues in doing this however: +

      +
        +
      • +

        + up_putc() is able to generate debug output in any context because it disables serial interrupts and polls the hardware directly. These polls may take many milliseconds and during that time, all interrupts are disable within the interrupt handler. This, of course, interferes with the real-time behavior of the RTOS. +

        +
        • +
      • +

        + The output generated by up_putc() is immediate and in real-time. The normal SYSLOG output, on the other hand, is buffered in the serial driver and may be delayed with respect to the immediate output by many lines. Therefore, the interrupt level SYSLOG ouput provided throug up_putc() is grossly out of synchronization with other debug output +

        +
        • +
      + +
      2. +
    2. +

      In-Memory Buffering. + If the RAMLOG SYSLOG channel is supported, then all SYSLOG output is buffered in memory. Interrupt level SYSLOG output is no different than normal SYSLOG output in this case. +

      +
      3. +
    3. +

      Serialization Buffer. + A final option is the use the an interrupt buffer to buffer the interrupt level SYSLOG output. In this case: +

      +
        +
      • +

        + SYSLOG output generated from interrupt level process in not sent to the SYSLOG channel immediately. Rather, it is buffered in the interrupt serialization buffer. +

        +
        • +
      • +

        + Later, when the next normal syslog output is generated, it will first empty the content of the interrupt buffer to the SYSLOG device in the proper context. It will then be followed by the normal syslog output. In this case, the interrupt level SYSLOG output will interrupt the normal output stream and the interrupt level SYSLOG output will be inserted into the correct position in the SYSLOG output when the next normal SYLOG output is generated. +

        +
        • +
      +

      + The SYSLOG interrupt buffer is enabled with CONFIG_SYSLOG_INTBUFFER. When the interrupt buffer is enabled, you must also provide the size of the interrupt buffer with CONFIG_SYSLOG_INTBUFSIZE. +

      +
      4. +
    + +

    6.4.3 SYSLOG Channel Options

    +

    6.4.3.1 SYSLOG Console Device

    +

    + The typical SYSLOG device is the system console. If you are using a serial console, for example, then the SYSLOG output will appear on that serial port. +

    +

    + This SYSLOG channel is automatically selected by syslog_initialize() in the LATE initialization phase based on configuration options. The configuration options that affect this channel selection include: +

    +
      +
    • +

      + CONFIG_DEV_CONSOLE. This setting indicates that the system supports a console device, i.e., that the character device /dev/console exists. +

      • +
    • +

      + CONFIG_SERIAL_CONSOLE. This configuration option is automatically selected when a UART or USART is configured as the system console. There is no user selection. +

      • +

      + CONFIG_SYSLOG_CONSOLE. This configuration option is manually selected from the SYSLOG menu. This is the option that acutally enables the SYSLOG console device.

    • +

      + CONFIG_ARCH_LOWPUTC. This is an indication from the architecture configuration that the platform supports the up_putc() interface. up_putc() is a very low level UART interface that can even be used from interrupt handling. +

      • +
    • +

      + CONFIG_SYSLOG_SERIAL_CONSOLE. This enables certain features of the SYSLOG operation that depend on a serial console. If CONFIG_ARCH_LOWPUTC is also selected, for example, then up_putc() will be used for the forced SYSLOG output. +

      • +
    +

    + Interrupt level SYSLOG output will be lost unless: (1) the interrupt buffer + is enabled to support serialization, or (2) a serial console is used and + up_putc() is supported. +

    +

    + NOTE: The console channel uses the fixed character device at /dev/console. The console channel is not synonymous with stdout (or file descriptor 1). stdout is the current output from a task when, say, printf() if used. Initially, stdout does, indeed, use the /dev/console device. However, stdout may subsequently be redirected to some other device or file. This is always the case, for example, when a transient device is used for a console -- such as a USB console or a Telnet console. The SYSLOG channel is not redirected as stdout is; the SYSLOG channel will stayed fixed (unless it is explicitly changed via syslog_channel()). +

    + +

    6.4.3.2 SYSLOG Character Device

    +

    + The system console device, /dev/console, is a character driver with some special properties. However, any character driver may be used as the SYSLOG output channel. For example, suppose you have a serial console on /dev/ttyS0 and you want SYSLOG output on /dev/ttyS1. Or suppose you support only a Telnet console but want to capture debug output /dev/ttyS0. +

    +

    + This SYSLOG device channel is selected with CONFIG_SYSLOG_CHAR and has no other dependencies. Differences fromthe SYSLOG console channel include: +

    +
      +
    • +

      + CONFIG_SYSLOG_DEVPATH. This configuration option string must be set provide the full path to the character device to be used. +

      • +
    • +

      + The forced SYSLOG output always goes to the bit-bucket. This means that interrupt level SYSLOG output will be lost unless the interrupt buffer is enabled to support serialization. +

      • +
    • +

      + CONFIG_SYSLOG_CHAR_CRLF. If CONFIG_SYSLOG_CHAR_CRLF is selected, then linefeeds in the SYSLOG output will be expanded to Carriage Return plus Linefeed. Since the character device is not a console device, the addition of carriage returns to line feeds would not be performed otherwise. You would probably want this expansion if you use a serial terminal program with the character device output. +

      • +
    +

    + References: drivers/syslog/syslog_devchannel.c and drivers/syslog/syslog_device.c +

    + +

    6.4.3.3 SYSLOG File Device

    +

    + Files can also be used as the sink for SYSLOG output. There is, however, a very fundamental difference in using a file as opposed the system console, a RAM buffer, or character device: You must first mount the file system that supports the SYSLOG file. That difference means that the file SYSLOG channel cannot be supported during the boot-up phase but can be instantiated later when board level logic configures the application environment, including mounting of the file systems. +

    +

    + The interface syslog_file_channel() is used to configure the SYSLOG file channel: +

    + +

    6.4.3.4 syslog_file_channel()

    +

    Function Prototype:

    +
      +#include <nuttx/syslog/syslog.h>
+#ifdef CONFIG_SYSLOG_FILE
+int syslog_file_channel(FAR const char *devpath);
+#endif
+
    +

    Description: + Configure to use a file in a mounted file system at devpath as the SYSLOG channel. +

    +

    + This tiny function is simply a wrapper around syslog_dev_initialize() and syslog_channel(). It calls syslog_dev_initialize() to configure the character file at devpath then calls syslog_channel() to use that device as the SYSLOG output channel. +

    +

    + File SYSLOG channels differ from other SYSLOG channels in that they cannot be established until after fully booting and mounting the target file system. This function would need to be called from board-specific bring-up logic AFTER mounting the file system containing devpath. +

    +

    + SYSLOG data generated prior to calling syslog_file_channel() will, of course, not be included in the file. +

    +

    + NOTE interrupt level SYSLOG output will be lost in this case unless the interrupt buffer is used. +

    + +

    Input Parameters: +

      +
    • +

      + devpath: The full path to the file to be used for SYSLOG output. This may be an existing file or not. If the file exists, + syslog_file_channel() will append new SYSLOG data to the end of the file. If it does not, then syslog_file_channel() will create the file. +

      • +
    +

    Returned Value: + Zero (OK) is returned on success; a negated errno value is returned on any failure. +

    +

    + References: drivers/syslog/syslog_filechannel.c, drivers/syslog/syslog_device.c, and include/nuttx/syslog/syslog.h. +

    + +

    6.4.3.5 SYSLOG RAMLOG Device

    +

    + The RAMLOG is a standalone feature that can be used to buffer any + character data in memory. There are, however, special configurations + that can be used to configure the RAMLOG as a SYSLOG channel. The RAMLOG + functionality is described in a more general way in the following + paragraphs. +

    + +

    6.4.4 RAM Logging Device

    +

    + The RAM logging driver is a driver that was intended to support debugging output (SYSLOG) when the normal serial output is not available. For example, if you are using a Telnet or USB serial console, the debug output will get lost -- or worse. For example, what if you want to debug the network over Telnet? +

    +

    + The RAM logging driver can also accept debug output data from interrupt handler with no special serialization buffering. As an added benefit, the RAM logging driver is much less invasive. Since no actual I/O is performed with the debug output is generated, the RAM logger tends to be much faster and will interfere much less when used with time critical drivers. +

    +

    + The RAM logging driver is similar to a pipe in that it saves the debugging output in a circular buffer in RAM. It differs from a pipe in numerous details as needed to support logging. +

    +

    + This driver is built when CONFIG_RAMLOG is defined in the Nuttx configuration. +

    + +

    6.4.4.1 dmesg

    +

    + When the RAMLOG (with SYSLOG) is enabled, a new NuttShell (NSH) command will appear: dmesg. The dmesg command will dump the contents of the circular buffer to the console (and also clear the circular buffer). +

    + +

    6.4.4.2 RAMLOG Configuration options

    +
      +
    • +

      + CONFIG_RAMLOG: Enables the RAM logging feature +

      • +
    • +

      + CONFIG_RAMLOG_CONSOLE: Use the RAM logging device as a system console. If this feature is enabled (along with CONFIG_DEV_CONSOLE), then all console output will be re-directed to a circular buffer in RAM. This might be useful, for example, if the only console is a Telnet console. Then in that case, console output from non-Telnet threads will go to the circular buffer and can be viewed using the NSH dmesg command. This optional is not useful in other scenarios. +

      • +
    • +

      + CONFIG_RAMLOG_SYSLOG: Use the RAM logging device for the SYSLOG interface. If this feature is enabled, then all debug output will be re-directed to the circular buffer in RAM. This RAM log can be viewed from NSH using the dmesg command. NOTE: Unlike the limited, generic character driver SYSLOG device, the RAMLOG can be used to capture debug output from + interrupt level handlers. +

      • +
    • +

      + CONFIG_RAMLOG_NPOLLWAITERS: The number of threads than can be waiting for this driver on poll(). Default: 4 +

      • +
    +

    + If CONFIG_RAMLOG_CONSOLE or CONFIG_RAMLOG_SYSLOG is selected, then the following must also be provided: +

    +
      +
    • +

      + CONFIG_RAMLOG_BUFSIZE: The size of the circular buffer to use. Default: 1024 bytes. +

      • +
    +

    + Other miscellaneous settings +

    +
      +
    • +

      + CONFIG_RAMLOG_CRLF: Pre-pend a carriage return before every linefeed that goes into the RAM log. +

      • +
    • +

      + CONFIG_RAMLOG_NONBLOCKING: Reading from the RAMLOG will never block if the RAMLOG is empty. If the RAMLOG is empty, then zero is returned (usually interpreted as end-of-file). If you do not define this, the NSH dmesg command will lock up when called! So you probably do want this! +

      • +
    • +

      + CONFIG_RAMLOG_NPOLLWAITERS: The maximum number of threads that may be waiting on the poll method. +

+NuttX-7.16 Release Notes
+------------------------
+
+The 116th release of NuttX, Version 7.16, was made on June 1, 2016,
+and is available for download from the Bitbucket.org website.  Note
+that release consists of two tarballs:  nuttx-7.16.tar.gz and
+apps-7.16.tar.gz.  These are available from:
+
+    https://bitbucket.org/nuttx/nuttx/downloads
+    https://bitbucket.org/nuttx/apps/downloads
+
+Both may be needed (see the top-level nuttx/README.txt file for build
+information).
+
+Additional new features and extended functionality:
+
+    * Core OS:
+
+      - Power Management: Add activity domain to all PM interfaces and
+        driver callbacks.  If CONFIG_PM_NDOMAINS == 1, then the legacy
+        behavior is preserved.  If CONFIG_PM_NDOMAINS > 1, then multiple
+        PM domains are supported.  This will allow separate control for
+        certain power management groups.  For example, a network can be
+        shut down without affect an ongoing UI (and vice versa).
+      - board_app_initialize():  board_app_initialize() now accepts an
+        argument that may be used to support initialization in different
+        configurations.
+
+    * File System and Block and MTD Drivers:
+
+      - N25Qxxx: Add MTD support for Micron N25Qxxx family of QSPI flash.
+        From Dave (ziggurat29).
+      - SST26F:  Add an MTD driver for SST26F spi/qspi flash devices (SPI
+        mode only).  From Sebastien Lorquet.
+      - File Descriptor Detach: Add logic to detach a file structure from a
+        file descriptor. This is for use only within the OS.  It permits an
+        open file or driver to be used across multiple threads.
+
+   * Networking and Network Drivers:
+
+      - listen()/accept():  Separate out psock_listen() and psock_accepti()
+        for internal, thread independent OS usage (i.e., without a socket
+        descriptor).
+      - VNC Server:  Add support for a VNC server.  This logic is code
+        complete and functional, but not well tested.
+
+    * Graphics and Graphic Drivers:
+
+      - Framebuffer driver:  Add a display number to each interface in order
+        to support multiple display devices.
+      - VNC Server:  Add support for a VNC server.  This logic is code
+        complete and functional, but not well tested.
+      - LCD Backpack: Add support for PCF8574 LCD Backpack driver. This
+        driver supports an interface board that is based on the PCF8574 I/O
+        expander and supports the HD44780-based (or compatible) LCD modules.
+        There are a myriad of different vendors of such, but they are
+        principally the same, save wiring and minor features like jumpers
+        for I2C addresses. This driver supports known and unknown variants.
+        From Dave (ziggurat29).
+
+    * Common Device Drivers:
+
+      - RTC:  Simplify the RTC interface.  The old interface was way too
+        complex and was not fully implemented anywhere.
+      - BH1750FVI:  Add a character driver for Rohm Ambient Light Sensor
+        BH1750FVI.  From Alan Carvalho de Assis.
+      - CAN:  Improve CAN error reporting. From Frank Benkert.
+      - aes.h:  Modifications to the crypto API needed for LPC43xx.  From
+        Alexander Vasiljev.
+      - ADC:  Interface no longer uses global adc_receive() call.  Added a
+        new bind() method to the ADC interface.  Now the ADC upper half
+        driver will register its receipt-of-data callback.  This change
+        allows the ADC lower half driver to be used with a differ ADC upper
+        half.
+
+     * Simulation Platform:
+
+      - Linux Host Networking:  Enhance networking support for the
+        simulation under Linux. Includes updated support for Linux TUN/TAP,
+        and the addition of support for Linux bridge devices.  From Steve.
+
+    * ARMv7-A, ARMv7-R, and ARMv7-M:
+
+      - ARMv7-M:  Convert more assembly language files for use with the IAR
+        toolchain.  From Kha Vo.
+      - ARMv7-A:  Complete re-design of SMP-related logic to initialize each
+        CPUn, n > 0, when CONFIG_SMP=y.
+
+    * Atmel SAMV7:
+
+      - Add a JTAG config and ERASE config to Kconfig to set the
+        CCFG_SYSIO SYSIO Pins.  From David Sidrane.
+      - System Reset: Add the up_systemreset interface to the samv7 arch.  The
+        approach is slightly different in that: 1) It enables ARCH_HAVE_RESET
+        and allows the user to set if, and for how long, to drive External
+        nRST signal. It also does not contain a default board_reset, as that
+        really should be done in the config's src if CONFIG_BOARDCTL_RESET
+        is defined.  From David Sidrane.
+
+    * Atmel SAMV7 Boards:
+
+      - SAMV71-XULT: Add configuration(s) that were be used to verify VNC
+        graphics output as well as mouse and keyboard input.
+
+    * NXP Freescale i.MX6 Boards:
+
+      - Sabre-6Quad:  The basic i.MX6 port is complete.  This is a minimal
+        port at present and probably still has some as-of-yet-undiscovered
+        issues.
+      - Sabre-6Quad: Basic SMP NSH configuration is now working.  But this
+        is probably only because the SMP test case does not stress the
+        logic.  There are know outstanding SMP issues as noted in the
+        Sabre-6Quad README.txt file.
+
+    * NXP Freescale LPC43xx:
+
+      - LPC4337jet100: Add definitions for the LPC4337jet100 chip.  From
+        Alexander Vasiljev.
+
+    * NXP Freescale LPC43xx Drivers:
+
+      - AES:  Add AES support.  From Alexander Vasiljev.
+
+    * STMicro STM32:
+
+      - STM32 L4: Add configuration options to allow SRAM2 to be used for
+        heap, or not at all, and to zero-initialize it on OS start, or not
+        at all. From Dave dev@ziggurat29.com.
+      - STM32 L4: Add support for HSE and MSI clocks, and auto trim of MSI
+        to LSE (needed for USB).  From Dave (ziggurat29)
+      - STM32 L4: Add support for unique id function to arch; modified board
+        to support unique id boardctl.  From Dave (ziggurat29)
+
+    * STMicro STM32 Drivers:
+
+      - STM32 F4 RTC: Add a custom RTC driver with support for alarms.  From
+        Neil Hancock.
+      - STM32 L4 QSPI: Add a QSPI driver with DMA support and (optional
+        memory mapped mode support. From Dave ziggurat29).
+      - STM32, STM32 L4, and STM32 F7 Serial:  Add support for compliant 
+        SD-style breaks. From David Sidrane.
+      - STM32 L4 CAN: Add CAN support for STM32L4.  From Sebastien Lorquet.
+      - STM32 1-Wire:  Add support for a custom 1-wire driver.  The serial
+        driver already supports a 1-wire interface, but this driver uses the
+        same serial logic to implement a lower half driver much like the
+        I2C lower half driver.  From Aleksandr Vyhovanec.
+      - STM32 L4 SPI: Add support for SPI 4 and 5 on stm32f411 chips. From
+        Konstantin Berezenko.
+      - STM32 ADC: Allow omitting use of channels in a lower part of PWM.
+        From Pierre-noel Bouteville.
+      - STM32 L4 I2C: Get I2C working for STM32L4.  From Dave (ziggurat29).
+
+    * STMicro STM32 Boards:
+
+      - STM3220G-EVAL:  Add support for both the IAR and uVision GCC IDEs.
+        From Kha Vo.
+      - STM32F429I Discovery:  Add support for the uVision GCC IDE.   From
+        Kha Vo.
+      - STM32F4 Discovery: Integrate BH1750FVI driver in the STM32F4 Discovery
+        board.  From Alan Carvalho de Assis.
+      - STM32L476VG Discovery:  Add support for QSPI based N25Qxxx flash.
+        From Dave (ziggurat29)
+      - STM32L476VG Discovery: Add board ioctls for allowing user application
+        to cause QSPI memory mapped mode to be engaged and disengaged.  Also
+        partitioned QSPI flash for file system and other (eventually xip).
+        From Dave (ziggurat29)
+      - Nucleo-144: Basic port for the Nucleo-144 board with the STM32F746ZG
+        MCU.  From Kconstantin Berezenko.
+      - STM32F103 Minimum: Add support for this minimual STM32F103CBT6 "blue"
+        board.  From Alan Carvalho de Assis.
+      - STM32F411E Discovery:  Add basic configuration for stm32f411e-disco
+        board with STM32F411VE chip.  From Konstantin Berezenko.
+
+    * Build/Configuration System:
+
+      - Moved NuttX repository to https://bitbucket.org/nuttx/nuttx.
+        Eliminated use of sub-modules.
+      - Add support for the IAR toolchain for the limited case of the ARMv7-M
+        architecture and the STM32 chip.  From Aleksandr Vyhovanec.
+      - make export: Pass top-level make to the script to allow -j greater
+        than 1.  From David Sidrane.
+      - fs/Kconfig:  Allow CONFIG_FS_WRITABLE to be manually selectable. This
+        is needed when there are no writable file systems, but write support
+        is still needed in BCH or FTL.
+      - arch/*/Makefile: Add definitions that can be overrided to use GCC
+        instead of LD in the final link.  From Paul Alexander Patience .
+
+    * Applications: apps/netutils:
+
+      - apps/netutils/esp8266:  ESP8266 driver application.  From Pierre-noel
+        Bouteville.
+
+    * Applications: apps/examples:
+
+      - apps/examples/alarm:  Add a simple test of the ALARM iotcl calls of
+        the RTC driver.
+      - apps/examples/nximage:  Add a configuration option to select
+        greyscale.
+
+    * Platforms: apps/platform:
+
+      - apps/platform/nucleo-144: Add platform files for NUCLEO-144
+        (NUCLEO-F746ZG).  From Mark Olsson.
+      - apps/examples/media:  You can now override the default device driver
+        path by providing an alternal path on the command line.  From
+        Sbastien Lorquet.
+
+Works-In-Progress:
+
+    * IEEE802.14.5/6LowPAN.  Hooks and framework for this effort were
+      introduced in NuttX-7.15.  Work has continued on this effort on
+      forks from the main repositories, albeit with many interruptions.
+      The completion of this wireless feature will postponed until at
+      least NuttX-7.17.
+
+    * i.MX6 SMP.  Partially functional, but there is more that still
+      needs to be done.
+
+Bugfixes.  Only the most critical bugfixes are listed here (see the
+ChangeLog for the complete list of bugfixes and for additional, more
+detailed bugfix information):
+
+    * Core OS:
+
+      - Various places:  Search for places where a stray semicolon following
+        an if condition cause the if body to be executed unconditionally.
+        Fixes in all SAM DMA logic, unionfs, OS signalling logic, and others.
+      - enter/leave_critical_section() may attempt to access task lists
+        before they have been initialized in the SMP configuration.
+
+    * File System/Block Drivers:
+
+      - SMART MTD:  Return code of smart_scan not checked, can cause success
+        result in failure case, leading to 'dev' pointer being invalid. From
+        Dave (ziggurat29)
+      - mount: Fix a backward debug assertion.  Noted by David Sidrane.
+
+    * Common Drivers:
+
+      - NRF24L01: Fix backward calculation of relative frequency.  Noted by
+        Henry Zhang.
+      - PCA9555 I/O expander: Fix an error in the PCA9555 driver: Under
+        certain error conditions, interrupts were not being re-enabled.
+        Sebastien Lorquet.
+      - ADS1255: Must not do SPI access from interrupt handler.  Use the
+        worker thread instead.  Must also lock the SPI bus before using it.
+      - Several SPI-based drivers modified.  All drivers that use SPI must
+        call SPI_LOCK and SPI_UNLOCK.  This is not optional.
+      - MS583730:  Fix a bug in crc computation for ms583730. Implement
+        POSIX read.
+
+    * Atmel SAMV7:
+
+      - Fix typo in MATRIX register definitions.  From Stefan Kolb.
+      - SAMV7 Tickless Mode: This is a fix to a problem in the handling of
+        the oneshot timer. Due to a wrong assumption concerning the behavior
+        directly after the start of the timer/counter the function
+        sam_oneshot_cancel() calculates the wrong remaining time. The code
+        assumes that the counter register is zero directly after the start
+        of the timer, but this is not true. To start the time/counter a
+        software trigger is invoked, this trigger starts the timer/count and
+        sets the counter register to zero, but the reset of the counter
+        register is not performed instantly. According to the datasheet:
+        "The counter can be reset by a trigger. In this case, the counter
+        value passes to zero on the next valid edge of the selected clock."
+        Thus the counter is set to zero between 0 and USEC_PER_TICK
+        microseconds after the clock was started.
+        In my fix I use the freerun count value to determine if at least one
+        tick passed since the start of the timer and thus if the value of
+        the oneshot counter is correct. I also tried to use the function
+        up_timer_gettime() to achieve this but, at least if compiled with
+        no optimization the problem vanishes without using the value of the
+        function, the function call takes too long.
+        Another problem treated in the fix is that if the oneshot timer/counter
+        is canceled, we only know the remaining time with a precision of
+        USEC_PER_TICK microseconds. This means the calculated remaining time
+        is between 0 and USEC_PER_TICK microseconds  too long. To fix this I
+        subtract one tick if the calculated remaining time is greater than
+        one tick and otherwise set the remaining time to zero. By doing so
+        the measured times are much more precise as without it.  From Stefan
+        Kolb.
+
+    * Atmel SAMA5:
+
+      - SAMA5:  Stefan Kolb's change to the SAMV7 Oneshot Timer should also
+        be applied to the SAMA5 oneshot time since the drivers are identical.
+
+    * Atmel SAM3/4:
+
+      - SAM3/4:  Stefan Kolb's change to the SAMV7 Oneshot Timer should also
+        be applied to the SAM3/4 oneshot time since the drivers are identical.
+
+    * Atmel SAMV7 Drivers:
+
+      - SAMV7 TWIHS (as well as SAM3/4 and SAMA5:  Ensure that the TWIHS
+        (i2c) hw get's its clock set when the sequence of
+        sam_i2cbus_initialize(), sam_i2cbus_uninitialize(), then
+        sam_i2cbus_initialize() or twi_reset() is called.  I found this a
+        while back in the stm32 family, so there may be more arch-es with
+        this sort of bug. I suppose any driver that has the notion of "do
+        not set the freq if it is already set" could be suspect.  From David
+        Sidrane.
+      - USBHS Device: Remove disabling of whole USB on suspend of USBHS.
+        This fix removes the disabling of the whole USB peripheral on
+        suspend interrupt. Its enough to freeze the clock instead. When
+        disabling the whole peripheral, the next wakeup-interrupt comes up
+        with an disabled clocking. The unfreeze clock has no effect, because
+        the master clock is disabled. This makes all registers, including
+        the IDR unwriteable and the IRQ falls in an endless loop blocking
+        the whole system. Furthermore the disabling of the peripheral clock
+        prevents hotplugging or reconnecting the USB.  From  Frank Benkert.
+      - MCAN: Fix missing unlock of device in MCAN mcan_txempty().  From
+        Frank Benkert.
+
+    * STMicro STM32:
+
+      - STM32 L4 Clocking: Problem with resetting backup domain clears
+        clocking options set up before in *rcc.c use INITS flag to avoid
+        magic reg value to detect power up reset state of RTC correct a
+        problem clearing interrupt flags (they weren't) which prevented an
+        alarm from ever being used more than once per reset cycle.  From
+        Dave (ziggurat29)
+
+    * STMicro STM32 Drivers:
+
+      - STM32L4 SPI: That STM32Lr SPI driver is quite different. They now
+        handle frames of arbitrary size between 4 and 16 bits. It was broken
+        before a new bit has to be set (RX fifo threshold) to handle <= 8-bit
+        transactions. If not set, the default is 16-bit packed >=8-bit
+        frames and the RXNE bit is never set (it is set when 16-bits are
+        received). weird things as always. This also add 8-bit access
+        routines to the data register, because a 16-bit access to the data
+        register when the frame size is below 9 bits is interpreted as a
+        packed dual frame exchange. Sebastien Lorquet.
+      - STM32:  Correct some bad commits that broke the LTDC display example.
+        From Marco Krahl.
+      - STM32 F4 RTC: Fix logic in F4 RTCC driver that prevent ALARM
+        interrupt.  From Neil Hancock.
+      - STM32 F1 ADC: Fix STM32 ValueLine ADC IRQ number selection. From
+        David Sidrane.
+
+    * STMicro STM32 Boards:
+
+      - STM32F429I Discovery:  Correct some bad commits that broke the LTDC
+        display example.  From Marco Krahl.
+
+    * TI Tiva:
+
+      - GPIO Interrupts: Fix a bug of GPIO falling-edge interrupt for tiva.
+        From Young.
+
+    * C Library:
+
+      - math: Add a NAN test on 'x' in asin function of lib_asin.c. Suggested
+        by Pierre-noel Bouteville.
+
+    * Build/Configuration System:
+
+      - Several Makefiles: Add .PHONY definitions to prevent 'clean up to date'
+        message weirdness when 'make clean' is done with no .config or
+        Make.defs file.

+ * STM32 F7 I2C Driver
+ *
+ * Supports:
+ *  - Master operation:
+ *      Standard-mode (up to 100 kHz)
+ *      Fast-mode (up to 400 kHz)
+ *      Fast-mode Plus (up to 1 MHz)
+ *      fI2CCLK clock source selection is based on STM32_RCC_DCKCFGR2_I2CxSRC
+ *      being set to HSI and the calulations are based on STM32_HSI_FREQUENCY
+ *      of 16mHz
+ *
+ *  - Multiple instances (shared bus)
+ *  - Interrupt based operation
+ *  - RELOAD support
+ *
+ * Unsupported, possible future work:
+ *  - More effective error reporting to higher layers
+ *  - Slave operation
+ *  - Support of fI2CCLK frequencies other than 16Mhz
+ *  - Polled operation (code present but untested)
+ *  - SMBus support
+ *  - Multi-master support
+ *  - IPMI
+ *
+ * Test Environment:
+ *
+ *  - STM32F7676ZI on ST Nucleo-144 Board (ST Part STM32F429ZIT6)
+ *
+ * Operational Status:
+ *
+ *  All supported features have been tested and found to be operational.
+ *
+ *  Although the RELOAD capability has been tested as it was required to
+ *  implement the I2C_M_NORESTART flag on F3 hardware, the associated
+ *  logic to support the transfer messages with more than 255 byte
+ *  payloads has not been  tested as the author lacked access to a real
+ *  device supporting these types of transfers.
+ *
+ * Performance Benchmarks: TBD
+ *
+ *  Time to transfer two messages, each a byte in length, in addition to the
+ *  START condition, in interrupt mode:
+ *
+ *  DEBUG enabled (development): TBDms
+ *      Excessive delay here is caused by printing to the console and
+ *      is of no concern.
+ *
+ *  DEBUG disabled (production): TBSus
+ *      Between Messages: TBDus
+ *      Between Bytes: TBDus
+ *
+ * Implementation:
+ *
+ *  - Device: structure as defined by the nuttx/i2c/i2c.h
+ *
+ *  - Instance: represents each individual access to the I2C driver, obtained by
+ *      the i2c_init(); it extends the Device structure from the nuttx/i2c/i2c.h;
+ *      Instance points to OPS, to common I2C Hardware private data and contains
+ *      its own private data including frequency, address and mode of operation.
+ *
+ *  - Private: Private data of an I2C Hardware
+ *
+ * High Level Functional Desecription
+ *
+ * This driver works with I2C "messages" (struct i2c_msg_s), which carry a buffer
+ * intended to transfer data to, or store data read from, the I2C bus.
+ *
+ * As the hardware can only transmit or receive one byte at a time the basic job
+ * of the driver (and the ISR specifically) is to process each message in the
+ * order they are stored in the message list, one byte at a time.  When
+ * no messages are left the ISR exits and returns the result to the caller.
+ *
+ * The order of the list of I2C messages provided to the driver is important and
+ * dependent upon the hardware in use.  A typical I2C transaction between the F3
+ * as an I2C Master and some other IC as a I2C Slave requires two messages that
+ * communicate the:
+ *
+ *    1) Subaddress (register offset on the slave device)
+ *    2) Data sent to or read from the device
+ *
+ * These messages will typically be one byte in length but may be up to 2^31
+ * bytes in length.  Incidentally, the maximum length is limited only because
+ * i2c_msg_s.length is a signed int for some odd reason.
+ *
+ * Interrupt mode relies on the following interrupt events:
+ *
+ *   TXIS  - Transmit interrupt
+ *           (data transmitted to bus and acknowedged)
+ *   NACKF - Not Acknowledge Received
+ *           (data transmitted to bus and NOT acknowledged)
+ *   RXNE  - Receive interrupt
+ *           (data received from bus)
+ *   TC    - Transfer Complete
+ *           (All bytes in message transferred)
+ *   TCR   - Transfer Complete (Reload)
+ *           (Current batch of bytes in message transferred)
+ *
+ * The driver currently supports Single Master mode only.  Slave mode is not
+ * supported.  Additionally, the driver runs in Software End Mode (AUTOEND
+ * disabled) so the driver is responsible for telling the hardware what to
+ * do at the end of a transfer.
+ *
+ * ------------------------------------------------------------------------------
+ *

+ *

+ *
+ *   This function supports bus clock frequencies of:

+ *      400Khz  (Fast Mode)
+ *      100Khz  (Standard Mode)

+ *
+ *   Attempts to set a different frequency will quietly provision the default
+ *   of 10Khz.
+ *
+ *   The only differences between the various modes of operation (std, fast,
+ *   fast+) are the bus clock speed and setup/hold times.  Setup/hold times are
+ *   specified as a MINIMUM time for the given mode, and naturally std mode
+ *   has the longest minimum times.  As a result, by provisioning setup/hold
+ *   times for std mode they are also compatible with fast/fast+, though some
+ *   performance degradation occurs in fast/fast+ as a result of the times
+ *   being somewhat longer than strictly required.  The values remain as they
+ *   are because reliability is favored over performance.
+ *
+ * Clock Selection:

+ * Description:
+ *   Send the START condition / force Master mode
+ *
+ *   A START condition in I2C consists of a single byte that contains both the
+ *   7 bit slave address and a read/write bit (0 = WRITE, 1 = READ).  If the
+ *   address is recognized by one of the slave devices that slave device will
+ *   ACK the byte so that data transfers can begin.
+ *
+ *   A RESTART (or repeated START per the I2CSPEC) is simply a START condition
+ *   issued in the middle of a transfer (i.e. after the initial START and before
+ *   a STOP).  A RESTART sends a new address byte and R/W bit to the bus. A
+ *   RESTART is optional in most cases but mandatory in the event the transfer
+ *   direction is changed.
+ *
+ *   Most of the time reading data from an I2C slave requires a WRITE of the
+ *   subaddress followed by a READ (and hence a RESTART in between).  Writing
+ *   to an I2C slave typically requires only WRITE operations and hence no
+ *   RESTARTs.
+ *
+ *   This function is therefore called both at the beginning of a transfer
+ *   (START) and at appropriate times during a transfer (RESTART).

+   *
+   * dcnt:  A running counter of the bytes in the current message waiting to be
+   *        transferred.  This is decremented each time a byte is transferred.
+   *        The hardware normally accepts a maximum of 255 bytes per transfer

+ * The external functions, stm32_spi1/2/3/4/5/6select and stm32_spi1/2/3/4/5/6status
+ * must be * provided by board-specific logic.  They are implementations of the select

+ * include/nuttx/spi/spi.h). All other methods (including stm32_spibus_initialize())
+ * are provided by common STM32 logic.  To use this common SPI logic on your
+ * board:
+ *
+ *   1. Provide logic in stm32_boardinitialize() to configure SPI chip select
+ *      pins.
+ *   2. Provide stm32_spi1/2/3/4/5/6select() and stm32_spi1/2/3/4/5/6status()
+ *      functions in your board-specific logic.  These functions will perform chip
+ *      selection and status operations using GPIOs in the way your board is
+ *      configured.
+ *   3. Add a calls to stm32_spibus_initialize() in your low level application
+ *      initialization logic
+ *   4. The handle returned by stm32_spibus_initialize() may then be used to bind the
+ *      SPI driver to higher level logic (e.g., calling
+ *      mmcsd_spislotinitialize(), for example, will bind the SPI driver to
+ *      the SPI MMC/SD driver).

+
+    This minnsh configuration is a "proof-of-concept" and not very usable in
+    its current state.  This configuration was created by disabling
+    everything possible INCLUDING file system support.  Without file system
+    support, NuttX is pretty much crippled.  Here are some of the
+    consequences of disabling the file system:
+
+    - All features that depend on the file system are lost:  device drivers,
+      mountpoints, message queues, named semaphores.
+
+    - Without device drivers, you cannot interact with the RTOS using POSIX
+      interfaces.  You would have to work with NuttX as with those other
+      tiny RTOSs:  As a scheduler and a callable hardare abstraction layer
+      (HAL).
+
+    - You cannot use any of the NuttX upper half device drivers since they
+      depend on the pseudo-file system and device nodes.  You can, of
+      course, continue to use the lower half drivers either directly.  Or,
+      perhaps, you could write some custom minnsh upper half drivers that
+      do not depend on a file system and expose a HAL interface.
+
+    There is a special version of readline() the NSH uses when there is no
+    file system.  It uses a special up_putc() to write data to the console
+    and a special function up_getc() to read data from the console.
+
+    - The current up_getc() implementationsa are a kludge.  They are
+      analogous to the up_putc() implementations:  They directly poll the
+      hardware for serial availability, locking up all lower priority tasks
+      in the entire system while they poll.  So a version of NSH that uses
+      up_getc() essentially blocks the system until a character is received.
+
+    This, of course, could be fixed by creating a special, upper half
+    implementation of the interrupt-driven serial lower half (like
+    stm32_serial) that just supports single character console I/O
+    (perhaps called up_putc and up_getc?).  The NSH could wait for serial
+    input without blocking the system.  But then that would increase the
+    footprint too.
+
+    So although the minnsh configurations are a good starting point for
+    making things small, they not are really very practical.  Why might
+    you want a NuttX minnsh solution?  Perhaps you have software that runs
+    on a family of chips including some very tiny MCUs.  Then perhaps having
+    the RTOS compatibility would justify the loss of functionality?
+
+    You can re-enable the file system and (true) serial console with
+    these settings:
+
+      Enable the file system:
+        CONFIG_NFILE_DESCRIPTORS=5
+        CONFIG_NFILE_STREAMS=5
+
+      Enable the console device:
+        CONFIG_DEV_CONSOLE=y
+
+      Disable most new NSH commands.  Some like 'ls' are really mandatory
+      with a file system:
+        CONFIG_NSH_DISABLE_xxx=y
+
+      Enable the upper half serial driver:
+        CONFIG_SERIAL=y
+        CONFIG_STANDARD_SERIAL=y
+
+      Enable the USART1 serial driver:
+        CONFIG_STM32_USART1=y
+        CONFIG_STM32_USART1_SERIALDRIVER=y
+        CONFIG_USART1_SERIAL_CONSOLE=y
+
+        CONFIG_USART1_2STOP=0
+        CONFIG_USART1_BAUD=115200
+        CONFIG_USART1_BITS=8
+        CONFIG_USART1_PARITY=0
+        CONFIG_USART1_RXBUFSIZE=16
+        CONFIG_USART1_TXBUFSIZE=16
+
+    With these changes, NSH should behave better  and we preserve the device
+    driver interface.  But this result in a total size increase of about
+    7KB:  That is about 5KB of additional OS support for the file system and
+    serial console PLUS about 2KB for the 'ls' command logic (including OS
+    support for opendir(), readdir(), closedir(), stat(), and probably other
+    things).

     configuration.  This configuration has far fewer features than the nsh
     configuration but is also a fraction of the size.
 
+    This minnsh configuration is a "proof-of-concept" and not very usable in
+    its current state.  This configuration was created by disabling
+    everything possible INCLUDING file system support.  Without file system
+    support, NuttX is pretty much crippled.  Here are some of the
+    consequences of disabling the file system:
+
+    - All features that depend on the file system are lost:  device drivers,
+      mountpoints, message queues, named semaphores.
+
+    - Without device drivers, you cannot interact with the RTOS using POSIX
+      interfaces.  You would have to work with NuttX as with those other
+      tiny RTOSs:  As a scheduler and a callable hardare abstraction layer
+      (HAL).
+
+    - You cannot use any of the NuttX upper half device drivers since they
+      depend on the pseudo-file system and device nodes.  You can, of
+      course, continue to use the lower half drivers either directly.  Or,
+      perhaps, you could write some custom minnsh upper half drivers that
+      do not depend on a file system and expose a HAL interface.
+
+    There is a special version of readline() the NSH uses when there is no
+    file system.  It uses a special up_putc() to write data to the console
+    and a special function up_getc() to read data from the console.
+
+    - The current up_getc() implementationsa are a kludge.  They are
+      analogous to the up_putc() implementations:  They directly poll the
+      hardware for serial availability, locking up all lower priority tasks
+      in the entire system while they poll.  So a version of NSH that uses
+      up_getc() essentially blocks the system until a character is received.
+
+    This, of course, could be fixed by creating a special, upper half
+    implementation of the interrupt-driven serial lower half (like
+    stm32_serial) that just supports single character console I/O
+    (perhaps called up_putc and up_getc?).  The NSH could wait for serial
+    input without blocking the system.  But then that would increase the
+    footprint too.
+
+    So although the minnsh configurations are a good starting point for
+    making things small, they not are really very practical.  Why might
+    you want a NuttX minnsh solution?  Perhaps you have software that runs
+    on a family of chips including some very tiny MCUs.  Then perhaps having
+    the RTOS compatibility would justify the loss of functionality?
+
+    You can re-enable the file system and (true) serial console with
+    these settings:
+
+      Enable the file system:
+        CONFIG_NFILE_DESCRIPTORS=5
+        CONFIG_NFILE_STREAMS=5
+
+      Enable the console device:
+        CONFIG_DEV_CONSOLE=y
+
+      Disable most new NSH commands.  Some like 'ls' are really mandatory
+      with a file system:
+        CONFIG_NSH_DISABLE_xxx=y
+
+      Enable the upper half serial driver:
+        CONFIG_SERIAL=y
+        CONFIG_STANDARD_SERIAL=y
+
+      Enable the USART1 serial driver:
+        CONFIG_STM32_USART1=y
+        CONFIG_STM32_USART1_SERIALDRIVER=y
+        CONFIG_USART1_SERIAL_CONSOLE=y
+
+        CONFIG_USART1_2STOP=0
+        CONFIG_USART1_BAUD=115200
+        CONFIG_USART1_BITS=8
+        CONFIG_USART1_PARITY=0
+        CONFIG_USART1_RXBUFSIZE=16
+        CONFIG_USART1_TXBUFSIZE=16
+
+    With these changes, NSH should behave better  and we preserve the device
+    driver interface.  But this result in a total size increase of about
+    7KB:  That is about 5KB of additional OS support for the file system and
+    serial console PLUS about 2KB for the 'ls' command logic (including OS
+    support for opendir(), readdir(), closedir(), stat(), and probably other
+    things).

     configuration.  This configuration has far fewer features than the nsh
     configuration but is also a fraction of the size.
 
+    This minnsh configuration is a "proof-of-concept" and not very usable in
+    its current state.  This configuration was created by disabling
+    everything possible INCLUDING file system support.  Without file system
+    support, NuttX is pretty much crippled.  Here are some of the
+    consequences of disabling the file system:
+
+    - All features that depend on the file system are lost:  device drivers,
+      mountpoints, message queues, named semaphores.
+
+    - Without device drivers, you cannot interact with the RTOS using POSIX
+      interfaces.  You would have to work with NuttX as with those other
+      tiny RTOSs:  As a scheduler and a callable hardare abstraction layer
+      (HAL).
+
+    - You cannot use any of the NuttX upper half device drivers since they
+      depend on the pseudo-file system and device nodes.  You can, of
+      course, continue to use the lower half drivers either directly.  Or,
+      perhaps, you could write some custom minnsh upper half drivers that
+      do not depend on a file system and expose a HAL interface.
+
+    There is a special version of readline() the NSH uses when there is no
+    file system.  It uses a special up_putc() to write data to the console
+    and a special function up_getc() to read data from the console.
+
+    - The current up_getc() implementationsa are a kludge.  They are
+      analogous to the up_putc() implementations:  They directly poll the
+      hardware for serial availability, locking up all lower priority tasks
+      in the entire system while they poll.  So a version of NSH that uses
+      up_getc() essentially blocks the system until a character is received.
+
+    This, of course, could be fixed by creating a special, upper half
+    implementation of the interrupt-driven serial lower half (like
+    stm32_serial) that just supports single character console I/O
+    (perhaps called up_putc and up_getc?).  The NSH could wait for serial
+    input without blocking the system.  But then that would increase the
+    footprint too.
+
+    So although the minnsh configurations are a good starting point for
+    making things small, they not are really very practical.  Why might
+    you want a NuttX minnsh solution?  Perhaps you have software that runs
+    on a family of chips including some very tiny MCUs.  Then perhaps having
+    the RTOS compatibility would justify the loss of functionality?
+
+    You can re-enable the file system and (true) serial console with
+    these settings:
+
+      Enable the file system:
+        CONFIG_NFILE_DESCRIPTORS=5
+        CONFIG_NFILE_STREAMS=5
+
+      Enable the console device:
+        CONFIG_DEV_CONSOLE=y
+
+      Disable most new NSH commands.  Some like 'ls' are really mandatory
+      with a file system:
+        CONFIG_NSH_DISABLE_xxx=y
+
+      Enable the upper half serial driver:
+        CONFIG_SERIAL=y
+        CONFIG_STANDARD_SERIAL=y
+
+      Enable the USART1 serial driver:
+        CONFIG_STM32_USART1=y
+        CONFIG_STM32_USART1_SERIALDRIVER=y
+        CONFIG_USART1_SERIAL_CONSOLE=y
+
+        CONFIG_USART1_2STOP=0
+        CONFIG_USART1_BAUD=115200
+        CONFIG_USART1_BITS=8
+        CONFIG_USART1_PARITY=0
+        CONFIG_USART1_RXBUFSIZE=16
+        CONFIG_USART1_TXBUFSIZE=16
+
+    With these changes, NSH should behave better  and we preserve the device
+    driver interface.  But this result in a total size increase of about
+    7KB:  That is about 5KB of additional OS support for the file system and
+    serial console PLUS about 2KB for the 'ls' command logic (including OS
+    support for opendir(), readdir(), closedir(), stat(), and probably other
+    things).

+  the above mentioned graphic may be helpful in indentifying a serial port.
+
+  There are 4 choices that can be made from the menuconfig:
+
+  CONFIG_NUCLEO_CONSOLE_ARDUINO or CONFIG_NUCLEO_CONSOLE_MORPHO or
+  CONFIG_NUCLEO_CONSOLE_VIRTUAL or CONFIG_NUCLEO_CONSOLE_NONE
+
+  The CONFIG_NUCLEO_CONSOLE_NONE makes no preset for the console. YOu shuld still visit
+  the U[S]ART selection and Device Drivers to disable any U[S]ART reamaing.
+
+  The CONFIG_NUCLEO_CONSOLE_ARDUINO configurations assume that you are using a
+  standard Arduio RS-232 shield with the serial interface with RX on pin D0 and
+  TX on pin D1 from USART6:

+/* The STM32F746ZGT6 has 1024 KiB of main FLASH memory.  This FLASH memory
+ * can be accessed from either the AXIM interface at address 0x0800:0000 or
+ * from the ITCM interface at address 0x0020:0000.
+ *
+ * Additional information, including the option bytes, is available at at
+ * FLASH at address 0x1ff0:0000 (AXIM) or 0x0010:0000 (ITCM).
+ *
+ * In the STM32F746ZGT6, two different boot spaces can be selected through
+ * the BOOT pin and the boot base address programmed in the BOOT_ADD0 and
+ * BOOT_ADD1 option bytes:
+ *
+ *   1) BOOT=0: Boot address defined by user option byte BOOT_ADD0[15:0].
+ *      ST programmed value: Flash on ITCM at 0x0020:0000
+ *   2) BOOT=1: Boot address defined by user option byte BOOT_ADD1[15:0].
+ *      ST programmed value: System bootloader at 0x0010:0000
+ *
+ * NuttX does not modify these option byes.  On the unmodified NUCLEO-144
+ * board, the BOOT0 pin is at ground so by default, the STM32F746ZGT6 will
+ * boot from address 0x0020:0000 in ITCM FLASH.
+ *
+ * The STM32F746ZGT6 also has 320 KiB of data SRAM (in addition to ITCM SRAM).
+ * SRAM is split up into three blocks:
+ *
+ *   1)  64 KiB of DTCM SRM beginning at address 0x2000:0000
+ *   2) 240 KiB of SRAM1 beginning at address 0x2001:0000
+ *   3)  16 KiB of SRAM2 beginning at address 0x2004:c000
+ *
+ * When booting from FLASH, FLASH memory is aliased to address 0x0000:0000

+/* The STM32F767ZIT6 has 2048 KiB of main FLASH memory.  This FLASH memory
+ * can be accessed from either the AXIM interface at address 0x0800:0000 or
+ * from the ITCM interface at address 0x0020:0000.
+ *
+ * Additional information, including the option bytes, is available at at
+ * FLASH at address 0x1ff0:0000 (AXIM) or 0x0010:0000 (ITCM).
+ *
+ * In the STM32F767ZIT6, two different boot spaces can be selected through
+ * the BOOT pin and the boot base address programmed in the BOOT_ADD0 and
+ * BOOT_ADD1 option bytes:
+ *
+ *   1) BOOT=0: Boot address defined by user option byte BOOT_ADD0[15:0].
+ *      ST programmed value: Flash on ITCM at 0x0020:0000
+ *   2) BOOT=1: Boot address defined by user option byte BOOT_ADD1[15:0].
+ *      ST programmed value: System bootloader at 0x0010:0000
+ *
+ * NuttX does not modify these option byes.  On the unmodified NUCLEO-144
+ * board, the BOOT0 pin is at ground so by default, the STM32F767ZIT6 will
+ * boot from address 0x0020:0000 in ITCM FLASH.
+ *
+ * The STM32F767ZIT6 also has 512 KiB of data SRAM (in addition to ITCM SRAM).
+ * SRAM is split up into three blocks:
+ *
+ *   1) 128 KiB of DTCM SRM beginning at address 0x2000:0000
+ *   2) 368 KiB of SRAM1 beginning at address 0x2002:0000
+ *   3)  16 KiB of SRAM2 beginning at address 0x2007:c000
+ *
+ * When booting from FLASH, FLASH memory is aliased to address 0x0000:0000
+ * where the code expects to begin execution by jumping to the entry point in
+ * the 0x0800:0000 address range.

 Where  is one of the following:
 
+  minnsh:
+  ------
+
+    This is a experiment to see just how small we can get a usable NSH
+    configuration.  This configuration has far fewer features than the nsh
+    configuration but is also a fraction of the size.
+
+    This minnsh configuration is a "proof-of-concept" and not very usable in
+    its current state.  This configuration was created by disabling
+    everything possible INCLUDING file system support.  Without file system
+    support, NuttX is pretty much crippled.  Here are some of the
+    consequences of disabling the file system:
+
+    - All features that depend on the file system are lost:  device drivers,
+      mountpoints, message queues, named semaphores.
+
+    - Without device drivers, you cannot interact with the RTOS using POSIX
+      interfaces.  You would have to work with NuttX as with those other
+      tiny RTOSs:  As a scheduler and a callable hardare abstraction layer
+      (HAL).
+
+    - You cannot use any of the NuttX upper half device drivers since they
+      depend on the pseudo-file system and device nodes.  You can, of
+      course, continue to use the lower half drivers either directly.  Or,
+      perhaps, you could write some custom minnsh upper half drivers that
+      do not depend on a file system and expose a HAL interface.
+
+    There is a special version of readline() the NSH uses when there is no
+    file system.  It uses a special up_putc() to write data to the console
+    and a special function up_getc() to read data from the console.
+
+    - The current up_getc() implementationsa are a kludge.  They are
+      analogous to the up_putc() implementations:  They directly poll the
+      hardware for serial availability, locking up all lower priority tasks
+      in the entire system while they poll.  So a version of NSH that uses
+      up_getc() essentially blocks the system until a character is received.
+
+    This, of course, could be fixed by creating a special, upper half
+    implementation of the interrupt-driven serial lower half (like
+    stm32_serial) that just supports single character console I/O
+    (perhaps called up_putc and up_getc?).  The NSH could wait for serial
+    input without blocking the system.  But then that would increase the
+    footprint too.
+
+    So although the minnsh configurations are a good starting point for
+    making things small, they not are really very practical.  Why might
+    you want a NuttX minnsh solution?  Perhaps you have software that runs
+    on a family of chips including some very tiny MCUs.  Then perhaps having
+    the RTOS compatibility would justify the loss of functionality?
+
+    STATUS:
+    2016-06-03:  Using that config I got this:
+
+        $ ls -l nuttx.bin
+        -rwxr-xr-x 1 alan alan 12543 Jun 3 17:58 nuttx.bin

+        $ arm-none-eabi-size nuttx
+        text data bss dec hex filename
+        12542 1 816 13359 342f nuttx
+
+      And this is free command from NuttX shell:
+
+        NuttShell (NSH)
+        nsh> free
+        total used free largest
+        Mem: 18624 2328 16296 16296
+       nsh>
+
+    2016-06-07:  As another experiment, I tried enabling just (1) the file
+    system, (2) the console device, and (3) the upper half serial driver in
+    the minnsh configuration.  With these changes, NSH should behave better 
+    and we preserve the device driver interface.  I made the following
+    configuration changes:
+
+      Enable the file system:
+        CONFIG_NFILE_DESCRIPTORS=5
+        CONFIG_NFILE_STREAMS=5
+
+      Enable the console device:
+        CONFIG_DEV_CONSOLE=y
+
+      Disable most new NSH commands.  Some like 'ls' are really mandatory
+      with a file system:
+        CONFIG_NSH_DISABLE_xxx=y
+
+      Enable the upper half serial driver:
+        CONFIG_SERIAL=y
+        CONFIG_STANDARD_SERIAL=y
+
+      Enable the USART1 serial driver:
+        CONFIG_STM32_USART1=y
+        CONFIG_STM32_USART1_SERIALDRIVER=y
+        CONFIG_USART1_SERIAL_CONSOLE=y
+
+        CONFIG_USART1_2STOP=0
+        CONFIG_USART1_BAUD=115200
+        CONFIG_USART1_BITS=8
+        CONFIG_USART1_PARITY=0
+        CONFIG_USART1_RXBUFSIZE=16
+        CONFIG_USART1_TXBUFSIZE=16
+
+    The resulting code was bigger as expected:
+
+      $ arm-none-eabi-size nuttx
+       text    data     bss     dec     hex filename
+      19853      88     876   20817    5151 nuttx
+
+    I am sure that other things that could be disabled were also drawn into
+    the build, so perhaps this could be reduced.  This amounts to a size
+    increase of around 7KB.
+
+    One major part of this size increase is due to the addition of the NSH
+    'ls' command.  Now, if I disable the 'ls' command, I get:
+
+      $ arm-none-eabi-size nuttx
+       text    data     bss     dec     hex filename
+      17804      80     864   18748    493c nuttx
+
+    Or an increase of only 5.1 KB.  This, of course, not only excludes the
+    'ls' command logic, but also the things that were drawn into the link
+    when 'ls' was enabled:  opendir(), readdir(), closedir(), stat(), and
+    probably other things.
+
+    So I think we can say that the cost of the file system and true serial
+    console device was about 5 KB (primarily OS support) and the cost of
+    the NSH 'ls' command (including OS support) is about 2KB.
+
+    2016-06-21:  Just checking the size after some big system changes:  The
+    size of the base configuration has actually dropped by a few bytes:
+
+     $ arm-none-eabi-size nuttx
+        text    data     bss     dec     hex filename
+      12526       4     816   13346    3422 nuttx

+
+/* The STM32F746NGH6 has 1024Kb of main FLASH memory.  This FLASH memory can
+ * be accessed from either the AXIM interface at address 0x0800:0000 or from
+ * the ITCM interface at address 0x0020:0000.
+ *
+ * Additional information, including the option bytes, is available at at
+ * FLASH at address 0x1ff0:0000 (AXIM) or 0x0010:0000 (ITCM).
+ *
+ * In the STM32F746NGH6, two different boot spaces can be selected through
+ * the BOOT pin and the boot base address programmed in the BOOT_ADD0 and
+ * BOOT_ADD1 option bytes:
+ *
+ *   1) BOOT=0: Boot address defined by user option byte BOOT_ADD0[15:0].
+ *      ST programmed value: Flash on ITCM at 0x0020:0000
+ *   2) BOOT=1: Boot address defined by user option byte BOOT_ADD1[15:0].
+ *      ST programmed value: System bootloader at 0x0010:0000
+ *
+ * NuttX does not modify these option byes.  On the unmodified STM32F746G
+ * DISCO board, the BOOT0 pin is at ground so by default, the STM32 will boot
+ * to address 0x0020:0000 in ITCM FLASH.
+ *
+ * The STM32F746NGH6 also has 320Kb of data SRAM (in addition to ITCM SRAM).
+ * SRAM is split up into three blocks:
+ *
+ *   1)  64Kb of DTCM SRM beginning at address 0x2000:0000
+ *   2) 240Kb of SRAM1 beginning at address 0x2001:0000
+ *   3)  16Kb of SRAM2 beginning at address 0x2004:c000
+ *
+ * When booting from FLASH, FLASH memory is aliased to address 0x0000:0000
+ * where the code expects to begin execution by jumping to the entry point in
+ * the 0x0800:0000 address range.
+ *
+ * For MPU support, the kernel-mode NuttX section is assumed to be 128Kb of
+ * FLASH and 4Kb of SRAM.  That is an excessive amount for the kernel which
+ * should fit into 64KB and, of course, can be optimized as needed (See
+ * also configs/stm32f746g-disco/scripts/kernel-space.ld).  Allowing the
+ * additional does permit addition debug instrumentation to be added to the
+ * kernel space without overflowing the partition.
+ *
+ * Alignment of the user space FLASH partition is also a critical factor:
+ * The user space FLASH partition will be spanned with a single region of
+ * size 2**n bytes.  The alignment of the user-space region must be the same.
+ * As a consequence, as the user-space increases in size, the alignment
+ * requirement also increases.
+ *
+ * This alignment requirement means that the largest user space FLASH region
+ * you can have will be 512KB at it would have to be positioned at
+ * 0x08800000.  If you change this address, don't forget to change the
+ * CONFIG_NUTTX_USERSPACE configuration setting to match and to modify
+ * the check in kernel/userspace.c.
+ *
+ * For the same reasons, the maximum size of the SRAM mapping is limited to
+ * 4KB.  Both of these alignment limitations could be reduced by using
+ * multiple regions to map the FLASH/SDRAM range or perhaps with some
+ * clever use of subregions.
+ *
+ * A detailed memory map for the 112KB SRAM region is as follows:
+ *
+ *   0x20001 0000:  Kernel .data region.  Typical size: 0.1KB
+ *   ------- ----   Kernel .bss  region.  Typical size: 1.8KB
+ *   0x20001 0800:  Kernel IDLE thread stack (approximate).  Size is
+ *                  determined by CONFIG_IDLETHREAD_STACKSIZE and
+ *                  adjustments for alignment.  Typical is 1KB.
+ *   ------- ----   Padded to 4KB
+ *   0x20001 1000:  User .data region.  Size is variable.
+ *   ------- ----   User .bss region  Size is variable.
+ *   0x20001 2000:  Beginning of kernel heap.  Size determined by
+ *                  CONFIG_MM_KERNEL_HEAPSIZE.
+ *   ------- ----   Beginning of user heap.  Can vary with other settings.
+ *   0x20004 c000:  End+1 of SRAM1

   2015-07-20:  STM32 F7 Ethernet appears to be functional, but has had
     only light testing.
 
-  2015-07-21:  Added a protected build version of the NSH configuration
-    (called knsh).  That configuration is close:  It boots, but I get
-    a hard fault each time I do the NSH "help" command.  Everything else
-    works fine.  I am thinking this is a corrupted binary; I am thinking
-    that there is a bad pointer in the command table.  But this is hard
-    to prove but possible because the steps to produce and load the
-    binary are awkward.

+ * Name: board_app_initialize
+ *
+ * Description:
+ *   Perform application specific initialization.  This function is never
+ *   called directly from application code, but only indirectly via the
+ *   (non-standard) boardctl() interface using the command BOARDIOC_INIT.
+ *
+ * Input Parameters:
+ *   arg - The boardctl() argument is passed to the board_app_initialize()
+ *         implementation without modification.  The argument has no
+ *         meaning to NuttX; the meaning of the argument is a contract
+ *         between the board-specific initalization logic and the the
+ *         matching application logic.  The value cold be such things as a
+ *         mode enumeration value, a set of DIP switch switch settings, a
+ *         pointer to configuration data read from a file or serial FLASH,
+ *         or whatever you would like to do with it.  Every implementation
+ *         should accept zero/NULL as a default configuration.
+ *
+ * Returned Value:
+ *   Zero (OK) is returned on success; a negated errno value is returned on
+ *   any failure to indicate the nature of the failure.
+ *

 drivers/syslog README File
 ==========================
 
-This README file discusses the SYLOG drivers that can be found in the
-drivers/syslog directory.  The syslogging interfaces are defined in the
-header file include/syslog.h.  In NuttX, "syslog output" is really
-synonymous to "debug output" and, therefore, the debugging interfaces
-defined in the header file include/debug.h are also sysloggin interfaces.
-
-By default, all system log output goes to console (/dev/console).  But that
-behavior can be changed by the defining CONFIG_SYSLOG in the NuttX
-configuration.  In that, case all low-level debug output will go through
-syslog_putc().
-
-One version of syslog_putc() is defined in fs/fs_syslog.c; that version is
-used when CONFIG_SYSLOG_CHAR is defined.  That version of syslog_putc()
-just integrates with the file system to re-direct debug output to a
-character device or to a file. A disadvantage of using the generic character
-device for the SYSLOG is that it cannot handle debug output generated from
-interrupt level handles.
-
-If CONFIG_SYSLOG_CHAR is not defined, then other custom SYSLOG drivers
-can be used.  These custom SYSLOG drivers can do things like handle
-unusual logging media and since they can avoid the general file system
-interfaces, can be designed to support debug output from interrupt handlers.
-
-Those custom SYSLOG drivers reside in this directory.

+SYSLOG Interfaces
+=================
+
+  Standard SYSLOG Interfaces
+  --------------------------
+  The NuttX SYSLOG is an architecture for getting debug and status
+  information from the system.  The syslogging interfaces are defined in the
+  header file include/syslog.h.  The primary interface to SYSLOG sub-system
+  is the function syslog() and, to a lesser extent, its companion vsyslog():
+
+  syslog() and vsyslog()
+  ----------------------
+  Prototypes:
+
+    int syslog(int priority, FAR const IPTR char *format, ...);
+    int vsyslog(int priority, FAR const IPTR char *src, va_list ap);
+
+  Description:
+
+    syslog() generates a log message. The priority argument is formed by
+    ORing the facility and the level values (see include/syslog.h). The
+    remaining arguments are a format, as in printf and any arguments to the
+    format.
+
+    The NuttX implementation does not support any special formatting
+    characters beyond those supported by printf.
+
+    The function vsyslog() performs the same task as syslog() with the
+    difference that it takes a set of arguments which have been obtained
+    using the stdarg variable argument list macros.
+
+  setlogmask()
+  ------------
+  The additional setlogmask() interface can use use to filter SYSLOG output:
+
+  Prototypes:
+
+    int setlogmask(int mask);
+
+  Description:
+
+    The setlogmask() function sets the logmask and returns the previous
+    mask. If the mask argument is 0, the current logmask is not modified.
+
+    The SYSLOG priorities are: LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR,
+    LOG_WARNING, LOG_NOTICE, LOG_INFO, and LOG_DEBUG.  The bit corresponding
+    to a priority p is LOG_MASK(p); LOG_UPTO(p) provides the mask of all
+    priorities in the above list up to and including p.
+
+    Per OpenGroup.org "If the maskpri argument is 0, the current log mask
+    is not modified."  In this implementation, the value zero is permitted
+    in order to disable all syslog levels.
+
+    REVISIT: Per POSIX the syslog mask should be a per-process value but in
+    NuttX, the scope of the mask is dependent on the nature of the build:
+
+    * Flat Build:  There is one, global SYSLOG mask that controls all output.
+      Protected Build:  There are two SYSLOG masks.  One within the kernel
+      that controls only kernel output.  And one in user-space that controls
+      only user SYSLOG output.
+    * Kernel Build:  The kernel build is compliant with the POSIX requirement:
+      There will be one mask for for each user process, controlling the
+      SYSLOG output only form that process.  There will be a separate mask
+      accessable only in the kernel code to control kernel SYSLOG output.
+     *
+
+  These are all standard interfaces as defined at http://pubs.opengroup.org/onlinepubs/009695399/functions/closelog.html
+
+  Debug Interfaces
+  ----------------
+  In NuttX, syslog output is really synonymous to debug output and,
+  therefore, the debugging interface macros defined in the header file
+  include/debug.h are also syslogging interfaces.  Those macros are simply
+  wrappers around syslog().  The debugging interfaces differ from the syslog
+  interfaces in that:
+
+    * They do not take a priority parameter; the priority is inherent in the
+      debug macro name.
+    * They decorate the output stream with information such as the file name
+    * They can each be disabled via configuration options.
+
+  Each debug macro has a base name that represents the priority and a prefix
+  that represents the sub-system.  Each macro is individually initialized by
+  both priority and sub-system.  For example, uerr() is the macro used for
+  error level messages from the USB subsystem and is enabled with
+  CONFIG_DEBUG_USB_ERROR.
+
+  The base debug macro names, their priority, and configuration variable are
+  summarized below:
+
+    * info().  The info() macro is the lowest priority (LOG_INFO) and is
+      intended to provide general information about the flow of program
+      execution so that you can get an overview of the behavior of the
+      program.  info() is often very chatty and voluminous and usually more
+      information than you may want to see.  The info() macro is controlled
+      via CONFIG_DEBUG_subsystem_INFO
+    * warn().  The warn() macro has medium priority (LOG_WARN) and is
+      controlled by CONFIG_DEBUG_subsystem_WARN.  The warn() is intended to
+      note exceptional or unexpected conditions that meigh be potential
+      errors or, perhaps, minor errors that easily recovered.
+    * err().  This is a high priority debug macro (LOG_ERROR) and controlled
+      by CONFIG_DEBUG_subsystem_ERROR.  The err() is reserved to indicate
+      important error conditions.
+    * alert(). The highest priority debug macro (LOG_EMERG) and is
+      controlled by CONFIG_DEBUG_ALERT.  The alert() macro is reserved for
+      use solely by assertion and crash handling logic.  It also differs
+      from the other macros in that it cannot be enabled or disabled per
+      subsystem.
+
+SYSLOG Channels
+===============
+
+  SYSLOG Channel Interfaces
+  -------------------------
+  In the NuttX SYSLOG implementation, the underlying device logic the
+  supports the SYSLOG output is referred to as a SYSLOG channel//.  Each
+  SYSLOG channel is represented by an interface defined in
+  include/nuttx/syslog/syslog.h:
+
+    /* This structure provides the interface to a SYSLOG device */
+
+    typedef CODE int (*syslog_putc_t)(int ch);
+    typedef CODE int (*syslog_flush_t)(void);
+
+    struct syslog_channel_s
+    {
+      /* I/O redirection methods */
+
+      syslog_putc_t sc_putc;    /* Normal buffered output */
+      syslog_putc_t sc_force;   /* Low-level output for interrupt handlers */
+      syslog_flush_t sc_flush;  /* Flush buffered output (on crash) */
+
+      /* Implementation specific logic may follow */
+    };
+
+  The channel interface is instantiated by calling syslog_channel():
+
+  syslog_channel()
+  ----------------
+  Prototype:
+
+    int syslog_channel(FAR const struct syslog_channel_s *channel);
+
+  Description:
+
+    Configure the SYSLOGging function to use the provided channel to
+    generate SYSLOG output.
+
+    syslog_channel() is a non-standard, internal OS interface and is not
+    available to applications.  It may be called numerous times as
+    necessary to change channel interfaces.
+
+  Input Parmeters:
+
+     * channel - Provides the interface to the channel to be used.
+
+  Returned Value:
+
+    Zero (OK)is returned on  success.  A negated errno value is returned
+    on any failure.
+
+  SYSLOG Channel Initialization
+  -----------------------------
+  The initial, default SYSLOG channel is established with statically
+  initialized global variables so that some level of SYSLOG output may be
+  available immediately upon reset.  This initialized data is in the file
+  drivers/syslog/syslog_channel.c.  The initial SYSLOG capability is
+  determined by the selected SYSLOG channel:
+
+    * In-Memory Buffer (RAMLOG).  Full SYSLOG capability as available at
+      reset.
+    * Serial Console.  If the serial implementation provides the low-level
+      character output function up_putc(), then that low level serial output
+      is available as soon as the serial device has been configured.
+    * For all other SYSLOG channels, all SYSLOG output goes to the bit-
+      bucket until the SYSLOG channel device has been initialized.
+
+  The syslog channel device is initialized when the bring-up logic calls
+  syslog_intialize():
+
+  syslog_initialize()
+  -------------------
+  Prototype:
+
+    #ifndef CONFIG_ARCH_SYSLOG
+    int syslog_initialize(enum syslog_init_e phase);
+    #else
+    #  define syslog_initialize(phase)
+    #endif
+
+  Description:
+
+    One power up, the SYSLOG facility is non-existent or limited to very
+    low-level output.  This function is called later in the initialization
+    sequence after full driver support has been initialized.  It installs
+    the configured SYSLOG drivers and enables full SYSLOGing capability.
+
+    This function performs these basic operations:
+
+    * Initialize the SYSLOG device
+    * Call syslog_channel() to begin using that device.
+    * If CONFIG_ARCH_SYSLOG is selected, then the architecture-specific
+      logic will provide its own SYSLOG device initialize which must include
+      as a minimum a call to syslog_channel() to use the device.
+
+  Input Parameters:
+
+    * phase - One of {SYSLOG_INIT_EARLY, SYSLOG_INIT_LATE}
+
+  Returned Value:
+    Zero (OK) is returned on success; a negated errno value is returned on
+    any failure.
+
+  Different types of SYSLOG devices have different OS initialization
+  requirements.  Some are available immediately at reset, some are available
+  after some basic OS initialization, and some only after OS is fully
+  initialized.  In order to satisfy these different initialization
+  requirements, syslog_initialize() is called twice from the boot-up logic:
+
+    * syslog_initialize() is called from the architecture-specific
+      up_initialize() function as some as basic hardware resources have been
+      initialized: Timers, interrupts, etc.  In this case,
+      syslog_initialize() is called with the argument SYSLOG_INIT_EARLY.
+    * syslog_initialize() is called again from os_start() when the full OS
+      initialization has completed, just before the application main entry
+      point is spawned.  In this case, syslog_initialize() is called with
+      the argument SYSLOG_INIT_LATE.
+
+  There are other types of SYSLOG channel devices that may require even
+  further initialization.  For example, the file SYSLOG channel (described
+  below) cannot be initialized until the necessary file systems have been
+  mounted.
+
+  Interrupt Level SYSLOG Output
+  -----------------------------
+  As a general statement, SYSLOG output only supports //normal// output from
+  NuttX tasks.  However, for debugging purposes, it is also useful to get
+  SYSLOG output from interrupt level logic.  In an embedded system, that is
+  often where the most critical operations are performed.
+
+  There are three conditions under which SYSLOG output generated from interrupt level processing can a included the SYSLOG output stream:
+
+  1. Low-Level Serial Output
+  --------------------------
+  If you are using a SYSLOG console channel (CONFIG_SYSLOG_CONSOLE) with a
+  serial console (CONFIG_SYSLOG_SERIAL_CONSOLE) and if the underlying
+  architecture supports the low-level up_putc() interface
+  (CONFIG_ARCH_LOWPUTC), then the SYLOG logic will direct the output to
+  up_putc() which is capable of generating the serial output within the
+  context of an interrupt handler.
+
+  There are a few issues in doing this however:
+
+    * up_putc() is able to generate debug output in any context because it
+      disables serial interrupts and polls the hardware directly.  These
+      polls may take many milliseconds and during that time, all interrupts
+      are disable within the interrupt handler.  This, of course, interferes
+      with the real-time behavior of the RTOS.
+    * The output generated by up_putc() is immediate and in real-time.  The
+      normal SYSLOG output, on the other hand, is buffered in the serial
+      driver and may be delayed with respect to the immediate output by many
+      lines.  Therefore, the interrupt level SYSLOG ouput provided throug
+      up_putc() is grossly out of synchronization with other debug output
+
+  2. In-Memory Buffering
+  ----------------------
+  If the RAMLOG SYSLOG channel is supported, then all SYSLOG output is
+  buffered in memory.  Interrupt level SYSLOG output is no different than
+  normal SYSLOG output in this case.
+
+  3. Serialization Buffer
+  -----------------------
+  A final option is the use the an "interrupt buffer" to buffer the
+  interrupt level SYSLOG output.  In this case:
+
+    * SYSLOG output generated from interrupt level process in not sent to
+      the SYSLOG channel immediately.  Rather, it is buffered in the
+      interrupt serialization buffer.
+    * Later, when the next normal syslog output is generated, it will first
+      empty the content of the interrupt buffer to the SYSLOG device in the
+      proper context.  It will then be followed by the normal syslog output.
+      In this case, the interrupt level SYSLOG output will interrupt the
+      normal output stream and the interrupt level SYSLOG output will be
+      inserted into the correct position in the SYSLOG output when the next
+      normal SYLOG output is generated.
+
+  The SYSLOG interrupt buffer is enabled with CONFIG_SYSLOG_INTBUFFER.  When
+  the interrupt buffer is enabled, you must also provide the size of the
+  interrupt buffer with CONFIG_SYSLOG_INTBUFSIZE.
+
+SYSLOG Channel Options
+======================
+
+  SYSLOG Console Device
+  ---------------------
+  The typical SYSLOG device is the system console.  If you are using a
+  serial console, for example, then the SYSLOG output will appear on that
+  serial port.
+
+  This SYSLOG channel is automatically selected by syslog_initialize() in
+  the LATE initialization phase based on configuration options.  The
+  configuration options that affect this channel selection include:
+
+    * CONFIG_DEV_CONSOLE.  This setting indicates that the system supports a
+      console device, i.e., that the character device /dev/console exists.
+    * CONFIG_SERIAL_CONSOLE.  This configuration option is automatically
+      selected when a UART or USART is configured as the system console.
+      There is no user selection.
+    * CONFIG_SYSLOG_CONSOLE.  This configuration option is manually selected
+      from the SYSLOG menu.  This is the option that acutally enables the
+      SYSLOG console device.  It depends on CONFIG_DEV_CONSOLE and it will
+      automatically select CONFIG_SYSLOG_SERIAL_CONSOLE if
+      CONFIG_SERIAL_CONSOLE is selected.
+    * CONFIG_ARCH_LOWPUTC.  This is an indication from the architecture
+      configuration that the platform supports the up_putc() interface.
+      up_putc() is a very low level UART interface that can even be used from
+      interrupt handling.
+    * CONFIG_SYSLOG_SERIAL_CONSOLE.  This enables certain features of the
+      SYSLOG operation that depend on a serial console.  If
+      CONFIG_ARCH_LOWPUTC is also selected, for example, then up_putc() will
+      be used for the forced SYSLOG output.
+
+  Interrupt level SYSLOG output will be lost unless:  (1) the interrupt buffer
+  is enabled to support serialization, or (2) a serial console is used and
+  up_putc() is supported.
+
+  NOTE: The console channel uses the fixed character device at /dev/console.
+  The console channel is not synonymous with stdout (or file descriptor 1).
+  stdout is the current output from a task when, say, printf() if used.
+  Initially, stdout does, indeed, use the /dev/console device.  However,
+  stdout may subsequently be redirected to some other device or file.  This
+  is always the case, for example, when a transient device is used for a
+  console -- such as a USB console or a Telnet console.  The SYSLOG channel
+  is not redirected as stdout is; the SYSLOG channel will stayed fixed (unless
+  it is explicitly changed via syslog_channel()).
+
+  References: drivers/syslog/syslog_consolechannel.c and
+  drivers/syslog/syslog_device.c
+
+  SYSLOG Character Device
+  -----------------------
+  The system console device, /dev/console, is a character driver with some
+  special properties.  However, any character driver may be used as the
+  SYSLOG output channel.  For example, suppose you have a serial console on
+  /dev/ttyS0 and you want SYSLOG output on /dev/ttyS1.  Or suppose you
+  support only a Telnet console but want to capture debug output
+  /dev/ttyS0.
+
+  This SYSLOG device channel is selected with CONFIG_SYSLOG_CHAR and has no
+  other dependencies.  Differences fromthe SYSLOG console channel include:
+
+    * CONFIG_SYSLOG_DEVPATH.  This configuration option string must be set
+      provide the full path to the character device to be used.
+    * The forced SYSLOG output always goes to the bit-bucket.  This means
+      that interrupt level SYSLOG output will be lost unless the interrupt
+      buffer is enabled to support serialization.
+    * CONFIG_SYSLOG_CHAR_CRLF.  If CONFIG_SYSLOG_CHAR_CRLF is selected, then
+      linefeeds in the SYSLOG output will be expanded to Carriage Return +
+      Linefeed.  Since the character device is not a console device, the
+      addition of carriage returns to line feeds would not be performed
+      otherwise.  You would probably want this expansion if you use a serial
+      terminal program with the character device output.
+
+  References: drivers/syslog/syslog_devchannel.c and
+  drivers/syslog/syslog_device.c
+
+  SYSLOG File Device
+  ------------------
+  Files can also be used as the sink for SYSLOG output.  There is, however,
+  a very fundamental difference in using a file as opposed the system
+  console, a RAM buffer, or character device:  You must first mount the
+  file system that supports the SYSLOG file.  That difference means that
+  the file SYSLOG channel cannot be supported during the boot-up phase but
+  can be instantiated later when board level logic configures the application
+  environment, including mounting of the file systems.
+
+  The interface syslog_file_channel() is used to configure the SYSLOG file
+  channel:
+
+  syslog_file_channel()
+  ---------------------
+  Prototype:
+
+    #ifdef CONFIG_SYSLOG_FILE
+    int syslog_file_channel(FAR const char *devpath);
+    #endif
+
+  Description:
+
+    Configure to use a file in a mounted file system at 'devpath' as the
+    SYSLOG channel.
+
+    This tiny function is simply a wrapper around syslog_dev_initialize()
+    and syslog_channel().  It calls syslog_dev_initialize() to configure
+    the character file at 'devpath then calls syslog_channel() to use that
+    device as the SYSLOG output channel.
+
+    File SYSLOG channels differ from other SYSLOG channels in that they
+    cannot be established until after fully booting and mounting the target
+    file system.  This function would need to be called from board-specific
+    bring-up logic AFTER mounting the file system containing 'devpath'.
+
+    SYSLOG data generated prior to calling syslog_file_channel will, of
+    course, not be included in the file.
+
+    NOTE interrupt level SYSLOG output will be lost in this case unless
+    the interrupt buffer is used.
+
+  Input Parameters:
+
+    * devpath - The full path to the file to be used for SYSLOG output.
+      This may be an existing file or not.  If the file exists,
+      syslog_file_channel() will append new SYSLOG data to the end of the
+      file.  If it does not, then syslog_file_channel() will create the
+      file.
+
+  Returned Value:
+
+    Zero (OK) is returned on success; a negated errno value is returned on
+    any failure.
+
+  References: drivers/syslog/syslog_filechannel.c,
+  drivers/syslog/syslog_device.c, and include/nuttx/syslog/syslog.h.
+
+  SYSLOG RAMLOG Device
+  --------------------
+  The RAMLOG is a standalone feature that can be used to buffer any
+  character data in memory.  There are, however, special configurations
+  that can be used to configure the RAMLOG as a SYSLOG channel.  The RAMLOG
+  functionality is described in a more general way in the following
+  paragraphs.
+
+RAM Logging Device
+==================
+
   The RAM logging driver is a driver that was intended to support debugging
-  output (aka, syslogging).  It might be used when the normal serial output
-  is not available.  For example, if you are using a Telnet or USB serial
-  console, the debug output will get lost since the USB Telnet session does
-  not use the serial console.
-
-  The RAM logginc driver is also useful when debug output on the serial
-  console would interfere with performance or with usability.  The debug
-  output is write to RAM very quickly and so interferes less with realtime
-  performance.  And since the output does not appear on the serial console
-  until you want it to, it does not interfere with the usability of the
-  serial console.  The NuttShell (NSH), for eample, supports a 'dmesg'
-  command that can be used to dump the buffered output when you want to
-  see it.
-
-  The RAM logging  driver is similar to a pipe in that it saves the
-  debugging output in a FIFO in RAM.  It differs from a pipe in numerous
+  output (SYSLOG) when the normal serial output is not available.  For
+  example, if you are using a Telnet or USB serial console, the debug output
+  will get lost -- or worse.  For example, what if you want to debug the
+  network over Telnet?
+
+  The RAM logging driver can also accept debug output data from interrupt
+  handler with no special serialization buffering.  As an added benefit, the
+  RAM logging driver is much less invasive.  Since no actual I/O is performed
+  with the debug output is generated, the RAM logger tends to be much faster
+  and will interfere much less when used with time critical drivers.
+
+  The RAM logging driver is similar to a pipe in that it saves the debugging
+  output in a circular buffer in RAM.  It differs from a pipe in numerous
   details as needed to support logging.
 
   This driver is built when CONFIG_RAMLOG is defined in the Nuttx
   configuration.
 
-  Configuration options:
-
-    CONFIG_RAMLOG - Enables the RAM logging feature
-    CONFIG_RAMLOG_CONSOLE - Use the RAM logging device as a system console.
-      If this feature is enabled (along with CONFIG_DEV_CONSOLE), then all
-      console output will be re-directed to a circular buffer in RAM.  This
-      is useful, for example, if the only console is a Telnet console.  Then
-      in that case, console output from non-Telnet threads will go to the
-      circular buffer and can be viewed using the NSH 'dmesg' command.
-    CONFIG_RAMLOG_SYSLOG - Use the RAM logging device for the syslogging
-      interface.  If this feature is enabled (along with CONFIG_SYSLOG),
-      then all debug output (only) will be re-directed to the circular
-      buffer in RAM.  This RAM log can be view from NSH using the 'dmesg'
-      command.  NOTE:  Unlike the limited, generic character driver SYSLOG
-      device, the RAMLOG *can* be used to generate debug output from interrupt
-      level handlers.
-    CONFIG_RAMLOG_NPOLLWAITERS - The number of threads than can be waiting
+  dmesg
+  -----
+  When the RAMLOG (with SYSLOG) is enabled, a new NuttShell (NSH) command
+  will appear:  dmesg.  The dmsg command will dump the contents of the
+  circular buffer to the console (and also clear the circular buffer).
+
+  RAMLOG Configuration options
+  ----------------------------
+
+    * CONFIG_RAMLOG - Enables the RAM logging feature
+    * CONFIG_RAMLOG_CONSOLE - Use the RAM logging device as a system
+      console. If this feature is enabled (along with CONFIG_DEV_CONSOLE),
+      then all console output will be re-directed to a circular buffer in
+      RAM.  This might be useful, for example, if the only console is a
+      Telnet console.  Then in that case, console output from non-Telnet
+      threads will go to the circular buffer and can be viewed using the NSH
+      dmesg command.  This optional is not useful in other scenarios.
+    * CONFIG_RAMLOG_SYSLOG - Use the RAM logging device for the syslogging
+      interface.  If this feature is enabled, then all debug output (only)
+      will be re-directed to the circular buffer in RAM.  This RAM log can
+      be viewed from NSH using the 'dmesg' command.  NOTE:  Unlike the
+      limited, generic character driver SYSLOG device, the RAMLOG *can* be
+      used to capture debug output from interrupt level handlers.
+    * CONFIG_RAMLOG_NPOLLWAITERS - The number of threads than can be waiting
       for this driver on poll().  Default: 4
 
-   If CONFIG_RAMLOG_CONSOLE or CONFIG_RAMLOG_SYSLOG is selected, then the
-   following may also be provided:
+  If CONFIG_RAMLOG_CONSOLE or CONFIG_RAMLOG_SYSLOG is selected, then the
+  following must also be provided:
+
+    * CONFIG_RAMLOG_BUFSIZE - The size of the circular buffer to use.
+      Default: 1024 bytes.
+
+  Other miscellaneous settings
 
-   CONFIG_RAMLOG_BUFSIZE - Size of the console RAM log.  Default: 1024
+    * CONFIG_RAMLOG_CRLF - Pre-pend a carriage return before every linefeed
+      that goes into the RAM log.
+    * CONFIG_RAMLOG_NONBLOCKING - Reading from the RAMLOG will never block
+      if the RAMLOG is empty.  If the RAMLOG is empty, then zero is returned
+      (usually interpreted as end-of-file).  If you do not define this, the
+      NSH 'dmsg' command will lock up when called!  So you probably do want
+      this!
+    * CONFIG_RAMLOG_NPOLLWAITERS - The maximum number of threads that may be
+      waiting on the poll method.

+ *
+ *   This tiny function is simply a wrapper around syslog_dev_initialize()
+ *   and syslog_channel().  It calls syslog_dev_initialize() to configure
+ *   the character file at 'devpath then calls syslog_channel() to use that
+ *   device as the SYSLOG output channel.
+ *
+ *   File SYSLOG channels differ from other SYSLOG channels in that they

+ *   SYSLOG data generated prior to calling syslog_file_channel will, of

+ *
+ *   NOTE interrupt level SYSLOG output will be lost in this case unless
+ *   the interrupt buffer is used.
+ *
+ * Input Parameters:
+ *   devpath - The full path to the file to be used for SYSLOG output.
+ *     This may be an existing file or not.  If the file exists,
+ *     syslog_file_channel() will append new SYSLOG data to the end of the
+ *     file.  If it does not, then syslog_file_channel() will create the
+ *     file.

 /* Debug macros to runtime filter the debug messages sent to the console.  In
  * general, there are four forms of the debug macros:
  *
- * [a-z]dbg() -- Outputs messages to the console similar to printf() except
- *    that the output is not buffered.  The first character indicates the
- *    system system (e.g., n=network, f=filesystm, etc.).  If the first
- *    character is missing (i.e., dbg()), then it is common.  The common
- *    dbg() macro is enabled by CONFIG_DEBUG.  Subsystem debug requires an
+ * [a-z]info() -- Outputs messages to the console similar to printf() except
+ *    that the output is not buffered.  Output is only generated if
+ *    CONFIG_DEBUG_INFO is defined.  The info macros are intended for
+ *    verbose "informational" debug output.  If you enable CONFIG_DEBUG_INFO,
+ *    then very chatty (and often annoying) output will be generated.
+ *
+ *    The first character of the macro name indicates the system system
+ *    (e.g., n=network, f=filesystm, etc.).  If the first character is
+ *    missing (i.e., _info()), then it is common.  The common _info() macro
+ *    is enabled simply with CONFIG_DEBUG_INFO.  Subsystem debug requires an
  *    additional configuration setting to enable it (e.g., CONFIG_DEBUG_NET
  *    for the network, CONFIG_DEBUG_FS for the file system, etc).
  *
- *    In general, error messages and output of importance use [a-z]dbg().
- *    [a-z]dbg() is implementation dependent but usually uses file descriptors.
+ *    In general, error messages and output of importance use [a-z]err().
+ *    [a-z]err() is implementation dependent but usually uses file descriptors.
  *    (that is a problem only because the interrupt task may have re-
- *    directed stdout).  Therefore [a-z]dbg() should not be used in interrupt
+ *    directed stdout).  Therefore [a-z]err() should not be used in interrupt
  *    handlers.
  *
- * [a-z]vdbg() -- Identical to [a-z]dbg() except that it also requires that
- *    CONFIG_DEBUG_VERBOSE be defined.  This is intended for general debug
- *    output that you would normally want to suppress.
- *
- * [a-z]lldbg() -- Identical to [a-z]dbg() except this is uses special
- *    interfaces provided by architecture-specific logic to talk directly
- *    to the underlying console hardware.  If the architecture provides such
- *    logic, it should define CONFIG_ARCH_LOWPUTC.
+ * [a-z]warn() -- Identical to [a-z]info() except that it also requires that
+ *    CONFIG_DEBUG_WARN be defined.  This is intended for important exception
+ *    conditions that are potential errors (or perhaps real errors with non-
+ *    fatal consequences).
  *
- *    [a-z]lldbg() should not be used in normal code because the implementation
- *    probably disables interrupts and does things that are not consistent with
- *    good real-time performance.  However, [a-z]lldbg() is particularly useful
- *    in low-level code where it is inappropriate to use file descriptors.  For
- *    example, only [a-z]lldbg() should be used in interrupt handlers.
+ * [a-z]err() -- Identical to [a-z]info() except that it also requires that
+ *    CONFIG_DEBUG_ERROR be defined.  This is intended for important error-related
+ *    information that you probably not want to suppress during normal debug
+ *    general debugging.
  *
- * [a-z]llvdbg() -- Identical to [a-z]lldbg() except that it also requires that
- *    CONFIG_DEBUG_VERBOSE be defined.  This is intended for general debug
- *    output that you would normally want to suppress.
+ * _alert() - is a special, high-priority, unconditional version that is really
+ *    intended only for crash error reporting.

+ * Name: openlog
+ *
+ * Description:
+ *   The openlog() function sets process attributes that affect subsequent
+ *   calls to syslog(). The ident argument is a string that is prepended to
+ *   every message. The logopt argument indicates logging options. Values
+ *   for logopt are constructed by a bitwise-inclusive OR of zero or more of
+ *   the following:
+ *
+ *     LOG_PID - Log the process ID with each message. This is useful for
+ *       identifying specific processes.
+ *
+ *     LOG_CONS - Write messages to the system console if they cannot be
+ *       sent to the logging facility. The syslog() function ensures that
+ *       the process does not acquire the console as a controlling terminal
+ *       in the process of writing the message.
+ *
+ *     LOG_NDELAY - Open the connection to the logging facility immediately.
+ *       Normally the open is delayed until the first message is logged.
+ *       This is useful for programs that need to manage the order in which
+ *       file descriptors are allocated.
+ *
+ *     LOG_ODELAY - Delay open until syslog() is called.
+ *
+ *     LOG_NOWAIT - Do not wait for child processes that may have been
+ *       created during the course of logging the message. This option
+ *       should be used by processes that enable notification of child
+ *       termination using SIGCHLD, since syslog() may otherwise block
+ *       waiting for a child whose exit status has already been collected.
+ *
+ *   The facility argument encodes a default facility to be assigned to all
+ *   messages that do not have an explicit facility already encoded. The
+ *   initial default facility is LOG_USER.
+ *
+ *   It is not necessary to call openlog() prior to calling syslog().

- *
- *   If the platform cannot support lowsyslog, then we will substitute the
- *   standard syslogging functions.  These will, however, probably cause
- *   problems if called from interrupt handlers, depending upon the nature of
- *   the underlying syslog device.
- *
- *   The function lowvsyslog() performs the same task as lowsyslog() with

+ *   we treat debug output from an interrupt handler.
+ *
+ * Input Parameters:
+ *   None
+ *
+ * Returned Value:
+ *   true if the calling task is and IDLE thread.
