* drivers/can.c and include/nuttx/can.h: Fix a problem in the CAN
upper-half driver that occurs only for CAN hardware that support a
H/W FIFO of outgoing CAN messages. In this case, there can be a
hang condition if both the H/W and S/W FIFOs are both full. In that
case, there may be no event to awaken the upper half driver. Add a
new (conditional) CAN upper half interface called can_txready() that
can be used by the lower half driver to avoid this hang condition
(2015-11-03).

* drivers/mtd/smart.c: Fixed SmartFS wear level error that occurs when
the logical sector size is too small to save all wear level status
bytes in a single sector. Logical sectors 1 and 2 were simply not

that sizeof(size_t) should be the same as sizeof(uinptr_t). mmsize_t
should always be 32-bits in any event. The last change to stddef has

* drivers/loop: Add a loop character device. losetup() and
loteardown() should not be called directory from applications.
Rather, these functions are now available as IOCTL commands to the
loop driver (2015-11-25).
* include/nuttx/net/netdev.h and several Ethernet drivers in arch/:
Most network drivers do not support statistics. Those that do only
support them when DEBUG is enabled. Each driver collects an
architecture specific set of statistics and there is no mechanism in
place to view those statistics. Thus, the driver feature was mostly
useless. This change standardizes the driver statistics and puts the
definition in the common network device structure defined in netdev.h
where they can be accessed by network applications. All Ethernet
drivers that collect statistics have been adapted to use these common
statistics (2015-11-26).

procfs (2015-11-27).

* sched/pthread/: CRITICAL BUGFIX: Logic was wiping out the indication
that of the type of a pthread. Hence, it could be confused as a
task. Found because this was causing a crash when /proc/nnn/cmdline

* configs/same70-xplained/nsh: The NSH configuration now seems fully
functional: serial console, LEDs, buttons, SDRAM, and HSMCI SD card
(2015-11-30).

NSH configuration for the SAME70-Xplained board (2015-11-20).

general (2015-12-01).
Gregory Nutt

* fs/procfs: The procfs file system can now be configured so that it
supports a runtime registration of procfs entries with
CONFIG_FS_PROCFS_REGISTER=y (2015-12-01).
* arch/arm/src/stm32/stm32_ccm_procfs.c: Is no longer a part of the
'base' procfs entries and can now only be supported via run time
registration with CONFIG_FS_PROCFS_REGISTER=y (2015-12-01).

* arm/arm/src/samv7/sam_tickless.c: Port the SAMA5/SAM4CM tickless
logic to the SAMV7 (2015-12-02).
* fs/semaphore: Named semaphores: Back out "fix" of 2015-10-22. It was
correct before. The change of 2015-10-22 probably broke named
semaphores (2015-12-02).
* arch/arm/src/samv7: Bring programmable clock logic from SAMA5 into
SAMV7 (2015-12-03).

to drivers/net. It is a driver a belongs in the OS. There are still
some interface related issues, however (2015-12-07).
* configs/: Update all configurations that use the Telnet daemon; those
configurations now need to separately enable the Telnet drvier
(2015-12-07).
Gregory Nutt
committed
* drivers/net/telnet.c: Now works like the loop device. A new interface
called telnet_initialize() registers a telnet session "factory"
device at /dev/telnet. Via ioctl, the factory device can create
instances of the telnet character devices at /dev/telnetN to support
Telnet sessions (2015-12-07).

packet is needed (2015-12-08).

Atmel toolchain in-flash strings. Atmel toolchain AVR compiler
provides a transparent in-flash object support using __flash and
__memx symbols. The former indicates to compiler that this is a flash-
based object. The later used with pointer indicates that the referenced
object may reside either in flash or in RAM. The compiler automatically
makes 32-bit pointer with flag indicating whether referenced object is
in flash or RAM and generates code to access either in run-time. Thus,
any function that accepts __memx object can transparently work with RAM
and flash objects.
For platforms with a Harvard architecture and a very small RAM like AVR
this allows to move all constant strings used in trace messages to flash
in the instruction address space, releasing resources for other things.
This change introduces IOBJ and IPTR type qualifiers. The 'I' indicates
that the object may lie in instruction space on a Harvard architecture
machine. For platforms that do not have __flash and __memx or similar
symbols IOBJ and IPTR are empty, making the types equivalent to, for
example, 'const char' and 'const char*'. For Atmel compiler these will
become 'const __flash char' and 'const __memx char*'. All printf()
functions and syslog() functions are changed so that the qualifier is
used with the format parameter. From Dimitry Kloper (2016-01-05).

which occurs if someone tries to set one of the pins 8-15. The problem is
that after the check if the pin is greater than 7 the variable addr is
incremented and used in the Call I2C_WRITEREAD. But later in the call to
the I2C_WRITE buf[0] is used as address but this address is not incremented

* fs/vfs/fs_poll.c: Fix handling of sem_tickwait() return value
Gregory Nutt
committed
sem_tickwait() does not return an -1+errno, it returns a negated
errno value. Noted by Freddie Chopin.

* drivers/analog/adc1242.c and include/nuttx/analog/adc1242.h: Driver
for the 24-Bit Differential Input ADC ADS1242 that communicates via
SPI with a MCU. Reading the ADC conversion result as well as configuring
the ADC, setting the input channel, etc. is implemented via ioctl calls.
However, it does not yet implement the standard ADC interface. From
* configs/board/src/xyz_cxxinitialize.c: Move CXX initialization logic
out of the RTOS and into the application space, specifically to
apps/platform/board, where it belongs (2016-01-29).

* arch/arm/src/lpc17xx: Backport lpc43xx I2C driver, replacing the
lpc17xx I2C driver. This gives us the I2C_TRANSFER method (2016-01-30).
* arch/arm/src/lpc11xx: Backport the lpc17xx I2C driver, replacing the
lpc11xx I2C driver. This gives us the I2C_TRANSFER method (2019-01-30).
* arch/arm/src/lpc2378: Backo the Lpc17xx I2C driver, replacing the
lpc2378 I2C driver. This gives us the I2C_TRANSFER method (2019-01-30).
* confgs/u-blox-c027: Support for the u-blox GSM and GPS module evaluation
board with NXP LPCExpresso LPC1768. The GSM module is one of LISA-C200,
LISA-U200 or SARA-G350. The GPS module is one of MAX-M7 or MAX-M8. From
Vladimir Komendantskiy (2016-01-31).
* drivers/, arch/, include/, numerous files: May restructuring of the I2C
interface necessary to eliminate some thread-safety issues inherent in
the legacy I2C interface design. This effects the interface definition,
all I2C clients, and all low-level I2C drivers. I have used caution,
but I still expect a change of this magnitude to introduce some errors.
Any bug reports of bug fixes will be much appreciated (2016-02-01).
* drivers/i2c/i2c_driver.c: Add an I2C character drivers to support
raw I2C data transfers for test applications (2016-02-02).

* I2C_RESET: Eliminate up_i2creset(). It should not be a global function;
Now it is an I2C interface method (2016-02-02).
* I2C: Rename up_i2cinitialize and up_i2cuninitilize to follow the correct
naming convention. These are not common interfaces used by the OS;
these are MCU-specific interfaces used only be MCU-specific code. The
the correct naming is xyz_i2cbus_initialize and xzy_i2cbus_uninitialize
where xzy is the MCU mnemonic (2016-02-02).
* Networking drivers that support CONFIG_NET_NOINTS: Fix a race condition
that can cause the TX poll timer to stop running. From Manuel Stuhn
(2016-02-03).
* All Network drivers: Remove the hsec parameter from devif_timer().
We can get better timing accuracy without it (2016-02-03).

thread safe (2016-02-03).
Gregory Nutt
committed
* sched/init/os_start.c and include/nuttx/init.h: Add a state variable
that provides the current level of OS initialization. This is needed by
some logic that may attempt to run early in the start-up sequence but
cannot run if a sufficient level of initialization has not yet occurred
(2016-02-05).
