* 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).

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

* 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).

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).

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).

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).

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

* drivers/, arch/, include/, numerous files: 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).

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).

list can be provided without adding more booleans (2016-10-11).
* Everywhere: Replace irqsave() with enter_critical_section(); replace
irqrestore() with leave_critical_section(). This is part of the onging
development of SMP support (2016-02-13).
* Conform to naming convention: Rename irqsave() to up_irq_save(); rename
irqrestore() to up_irq_restore(). These should no longer be used. If
your code still uses them, please switch to enter_critical_section()

up_irq_enable() (2016-02-14).
* sched/signal and include/nuttx/sched.h: Move the list of signal
actions from the TCB to the group structure. Signal handlers are not
per thread but, rather, per task group. I know, I preferred it the
other way too, but this is more compliant with POSIX (2016-02-18).

needed by drivers in order to recover from error conditions (2016-03-05)
* AT24xx driver: Correct missing address calculation logic. From Frank
Benkert (2016-03-08).
* arch/ renaming: current_regs renamed to g_current_regs in all

g_current_regs is now an array of dimension 1 in most case but of higher
dimension of the architecuture supports multiple CPUs (2016-03-09).
* MTD: Increase block size in mtd_geometry_s to 32-bits (2016-03-09).
* include/nuttx/clock.h: Missing parenteses in MSEC2TICK macro can
cause wrong calculations. From Stefan Kolb (2016-03-09).
* Build system: Added a 'make olddefconfig' target that will refresh
a .config file without interaction. tools/refesh.sh now has a --silent
option so that it can be used in batch modes without human input
(2016-03-09).
* tools/testbuild.sh: .config files were not being updated because (a)
kconfig-conf was being called in the wrong directory and (b) apps/Kconfig

* arch/arm/src/samv7/sam_usbdevhs.c: The USB driver has had some issue that
would occasionally cause loss of packets. Back last December, a fix was
put in for this but the fix apparently worsens the problem; now causing
hangs. The basic problem is that the number of busy banks (NBUSYBKS)
status is not real time but is delayed. This was fixed; now when the DMA
completes and NBUSYBKS > 0, the NBUSYBK is interrupt is enabled and the
operations are deferred until NBUSYBKS is truly zero (2016-03-17).

* PM: 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) (2016-03-27).

sigset() is the System V function; signal() is the obsoleted POSIX

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

* configs/*/src/tiva_timer.c: Tiva boards: Fix a naming collision,
rename board-specific function from tiva_timer_initialize() to
tiva_timer_configure() to remove conflict (2016-05-23).
* arch/arm/src/sam*: 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 (2016-05-23).
* arch/arm/src/samv7: 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 (2016-05-23).
* arch/arm/include/lpc43xx and src/lpc43xx: Adds definitions for the
LPC4337jet100 chip. From Alexander Vasiljev (2016-05-24).
* Many files: board_app_initialize() now accepts an argument that may
be used to support initialization in different configurations
(2016-05-24).
* arch/arm/src/samv7: 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 (2015-05-25).
* drivers/lcd: Add support for PCF8574 LCD Backpack driver. This driver
supports an interface board that is based on the PCF8574 io 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, 2013-6-26).
* arch/arm/stm32: 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 (2015-05-25).

* drivers/analog/adc.c, include/nuttx/analog/adc.h, and all ADC lower
half drivers: 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
(2016-05-26).
* drivers/analog/ads1255.c: Must not do SPI access from interrupt
handler. Use the worker thread instead. Must also lock the SPI bus
before using it. (2015-05-26).
* drivers/: Several SPI-based drivers modified. All drivers that use
SPI must call SPI_LOCK and SPI_UNLOCK. This is not optional
(2016-05-26).
* drivers/sensors: Fix a bug in crc computation for ms583730.
Implement POSIX read (2016-05-27).
* arch/arm/src/samv7: 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(â¦) 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(â¦) 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
(2016-05-27).
