* STM32 DMA2D: fix an error in up_dma2dcreatelayer where an invalid
pointer was returned when a certain underlying function failed. From
Jens Gräf (2016-10-07).
* include/nuttx/fs/nxffs.h: Needs forward reference to struct mtd_dev_s
and needs to include stdbool.h (2016-10-09).

configs/nr5m100-nexys4 board. I will be making the FPGA code for
this available soon (within a week I would say). The board support on
this is pretty thin, but it seems like maybe a good idea to get the base

* arch/arm/src/stm32: add TIM8 to STM32F103V pinmap. From Maciej Wójcik
(2016-10-19).
* libc/locale: Allows c++ code to compile with or without
CONFIG_LIBC_LOCALE and will generate a link error if CONFIG_LIBC_LOCALE
is not defined and setlocale is referneced. With CONFIG_LIBC_LOCALE
defined setlocale will act as if MB string is not supported and return
"C" for POSIX. C and "". From David Sidrane (2016-10-19).
* Add vectors for interrupt levels 2-6 (2016-10-20).
* strtof: Add strtof() as simply a copy of strtod with types and
limits changed (2016-10-20).
* arch/arm/src/stm32v7: Register the watchdog device at the configured
device path CONFIG_WATCHDOG_DEVPATH vs. hard-coded /dev/wdt. From Frank
Benkert (2016-10-21).
* configs/*/defdonf The buttons example was changed to archbuttons. As
a result all of the button configurations are broken and need some
renaming in the defconfig files. Noted by Frank Berkert (2016-10-21).
* configs/stm32f103-minimum: Add support to PWM on STM32F103-Minimum
board. From Alan Carvalho de Assis (2016-10-21).

* libc/unisted: Add strtold() (2016-10-22).
* sscanf: Use strtof() instead of strtod() if a short floating point
value was requested. The should help performance with MCUs with 32-bit
FPU support with some additional code size (2016-10-22).
* Remove support for software prioritization of interrupts (2016-10-23).
* drivers/net/tun.c: Fix bug in TUN interface driver. From Max
Nekludov (2016-10-24).
* arch/arm/src/stm32: A new implementation of the STM32 F4 I2C bottom
half. The commin I2C as this did not handled correctly in the current
implementation (see also https://github.com/PX4/NuttX/issues/54). The
changes almost exclusively affect the ISR. From Max Kriegleder
(2016-10-24).
* arch/arm/src/stm32l4: Fix I2C devices RCC registers. From Sebastien
Lorquet (2016-10-25).
* arch/arm/src/stm32l4: Enable and renames for 32l4 UARTs 4 and 5.
From Sebastien Lorquet (2016-10-25).
* configs/stm32f103-minimum: Fix Timers 2 to 7 clock frequencies.
From Alan Carvalho de Assis (2016-10-25).
* arch/arm/src/stm32: Initial implemention of the STM32 F37xx SDADC
module. There are also changes to ADC, DAC modules. SDADC has only been
tested in DMA mode and does not support external TIMER triggers. This
is a work in progress. From Marc Rechté (2016-10-25).
* Add logic to attach peripheral interrupt sources to CPU interrupts
(2016-10-25).
* CHxN channels are always outputs. From Sebastien Lorquet
(2016-10-26).
* sched/semaphore: Within the OS, when a thread obtains a semaphore
count it must call sem_addholder() if CONFIG_PRIORITY_INHERITANCE is
enabled. If a count is available, then sem_wait() calls
sem_addholder(), otherwise it waited for the semaphore and called
sem_addholder() when it eventually received the count.
This caused a problem when the thread calling sem_wait() was very
low priority. When it received the count, there may be higher
priority threads "hogging" the CPU that prevent the lower priority
task from running and, as a result, the sem_addholder() may be
elayed indefinitely.
The fix was to have sem_post() call sem_addholder() just before
restarting the thread waiting for the semaphore count.
This problem was noted by Benix Vincent who also suggested the
solution (2016-10-26).
* configs/stm32f103-minimum: Add RGB LED support on STM32F103 Minimum
board. From Alan Carvalho de Assis (2016-10-26).
* arch/arm/src/stm32f7: stm32_i2c.c Dejavu. Fixes a bug previously
found in the F4. From David Sidrane (2016-10-26).
* arch/arm/src/stm32f7: stm32f76xx77xx_pinmap.h Missed one. From
David Sidrane (2016-10-26).
* LPC32xx serial: Fix a typo in ioctl TIOCSRS485 ioctl. From Vytautas
Lukenskas (2016-10-27).
* sched/clock: Correct clock initialization. The correct range for
the month is 0-11 but is entered as 1-12 in the .config file
(2016-10-27).
* arch/*/include: Add architecture-specific inttypes.h. From Paul
A. Patience (2016-10-27).
* sched/Kconfig: Add ranges to START_YEAR, MONTH, and DAY (2016-10-28).
* configs/nucleo-f303re: Add STM32 F303RE hello configuration; remove
duplicate setting from board.h. From Marc Rechté (2016-10-18).
* arch/arm/src/lpc32xx: Restore RS485 mode on serial port open (if
RS485 is enabled via menuconfig). From Vytautas Lukenskas (2016-10-28).
* arch/arm/src/stm32f7: otgdev fixed typo. From David Sidrane
(2016-10-28).
* arch/xtensa: Basic architectural support for Xtensa processors and
the Expressif. ESP32 added. Totally untested on initial release
(2016-10-31).
* configs/esp32-core: Basic support for Expressif ESP32 Core v2 board
added. The initial release includes an NSH and an SMP test
configuration. Totally untested on initial relesae (2016-10-31).
* configs/bambino-200e: Add basic support to Micromint Bambino 200E
board. This includes contributions from Jim Wolfman. From Alan
Carvalho de Assis (2016-11-01).
* drivers/mtd/at24xx.c: Added EEPROM timeout. Fromo Aleksandr
Vyhovanec (2016-11-02).
* arch/misoc: Adds basic support for the Misoc procoessors and the
LM32 in particular. From Ramtin Amin (2016-11-01).
* configs/misoc. Board support for testing Misoc LM32 with Qemu.
From Ramtin Amin (2016-11-01).
* arch/arm/src/stm32: I think, that Size is (highest address+1 - Base
address). Base address has been removed and if address+count >= size
we are outside of the Flash. From David Sidrane (2016-11-01).
* sched/semaphore, sched/phread/, libc/semaphore, libc/pthread: Add
pthread_mutexattr_get/set_protocol and non-standard sem_get/set_protocol.
These may use to enable or disable priority inheritance on a single
semaphore (2016-11-02).
* arch/arm/src/stm32: Fix ADC compilation error when DMA isn't enabled.
From Paul A. Patience (2016-11-02).
* drivers/ and drivers/spi: Fix Kconfig warning. This commit moves the
ARCH_HAVE_SPI options outside the check for SPI. Those options don't
depend on SPI, and Kconfig files in arch/ enable them even if SPI isn't
enabled.
Sourcing the driver's Kconfig in drivers/Kconfig only if support for
the driver is enabled prevents us from defining these ARCH_HAVE options
in the driver's Kconfig. We should probably remove the other checks in
drivers/Kconfig and check if the drivers are enabled only in their
Kconfig. From Paul A. Patience (2016-11-02).
* Move protoypes for the non-standard include/semaphore.h file to the
non-standard include/nuttx/semaphore.h with the other non-standard
semaphore interfaces (2016-11-02).
* include/semaphores.h: Provide macros for sem_setprotocol() and
sem_getprotocol() if priority inheritance is not enabled. More
SEM_PRIO_* definitions to include/nuttx/semaphore.h (2016-11-02).
* drivers/serial.c: Make sure that priority inheritance is not
enabled for the signaling semaphores used in the serial driver
(2016-11-03).
* arch/arm/src/stm32f7: Fix to SPI-Master driver. Without this the
chip select decoding feature will not work properly. From Michael
Spahlinger (2016-11-03).
* drivers/, net/, fs/, sched, arch/, graphics/, libnx,: Disable
priority inheritance on all semaphores used for signaling (2016-11-03).
* sched/semaphore: Handle a case of missing proxy for sem_setprotocol.
Reorder so that (1) this error is avoided, and (2) >No proxy is needed
if priority inheritance is not enabled (2016-11-03).
* config/*/defconfgs: More fallout from name change of
apps/examples/buttons to archbuttons (2016-11-03).
* configs/nucleo_f303re: Various fixes to get the adc configuration
building again after PR. Refresh all configurations (2016-11-03).
* arch/misoc/src/common: Add interrupting Misoc serial driver. From
Ramtin Amin (2016-11-04)
* Fix a number of header files with mismatched 'extern C {' and '}'
(2016-11-05).
* Provide do-nothing stubs for mutex attribute interfaces if features
ot enabled. pthread_cond includes a signaling semaphore and should
call sem_setprotocol (2016-11-05).
* arch/arm/src/armv7-r: Fix compilation error. This commit fixes
compilation errors on MPU support for ARMv7-R. From Heesub Shin
(2016-11-06).
* arch/arm/src/armv7-r: fix invalid drbar handling. In ARMv7-R,
[31:5] bits of DRBAR is physical base address and other bits are
reserved and SBZ. Thus, there is no point in passing other than the
base address. From Heesub Shin (2016-11-06).
* arch/arm/src/armv7-r: Remove the redundant update on SCTLR.
mpu_control() is invoking cp15_wrsctlr() around SCTLR update
redundantly. From Heesub Shin (2016-11-06).
* arch/arm/src/armv7-r: add new Kconfig entries for d/i-cache.
Unlike in ARMv7-A/M, Kconfig entries for data and instruction caches
are currently missing in ARMv7-R. This commit adds those missing
Kconfig entries. Actual implmenetation for those functions will be
added in the subsequent patches. From Heesub Shin (2016-11-06).
* arch/arm/src/armv7-r: add cache handling functions. This commit
adds functions for enabling and disabling d/i-caches which were
missing for ARMv7-R. From Heesub Shin (2016-11-06).
* arch/arm/src/armv7-r: fix typo in mpu support. s/ARMV7M/ARMV7R/g.
From Heesub Shin (2016-11-06).
* arch/arm/src/armv7-r: fix CPSR corruption after exception handling.
A sporadic hang with consequent crash was observed when booting. It
seemed to be caused by the corrupted or wrong CPSR restored on return
from exception. NuttX restores the context using code like this:
msr spsr, r1
GCC translates this to:
msr spsr_fc, r1
As a result, not all SPSR fields are updated on exception return.
This should be:
msr spsr_fsxc, r1
On some evaluation boards, spsr_svc may have totally invalid value at
power-on-reset. As it is not initialized at boot, the code above may
result in the corruption of cpsr and thus unexpected behavior.
From Heesub Shin (2016-11-06).
* arch/arm/src/armv7-r: fix to restore the Thumb flag in CPSR. Thumb
flag in CPSR is not restored back when the context switch occurs while
executing thumb instruction. From Heesub Shin (2016-11-06).
* sched/wqueue: When queuing new LP work, don't signal any threads
if they are all busy. From Heesub Shin (2016-11-06).
* sched/wqueue: Signal sent from work_signal() may interrupt the low
priority worker thread that is already running. For example, the worker
thread that is waiting for a semaphore could be woken up by the signal
and break any synchronization assumption as a result. It also does not
make any sense to send signal if it is already running and busy. This
commit fixes it. From Heesub Shin (2016-11-06).
* arch/arm/src/stm32f7: STM32F7 SD/MMC driver depends on
CONFIG_SDIO_DMA which is only defined in stm32/Kconfig. Changed to
CONFIG_STM32F7_SDMMC_DMA and defined in stm32f7/Kconfig (2016-11-07).
* arch/arm/src/stm32: Add PWM driver support for STMF37xx. The
changes have been tested successfuly for TIM4 and TIM17 (different
IPs). From Marc Rechté (2016-11-07).
* sched/semaphore: sem_trywait() no longer modifies the errno value
UNLESS an error occurs. This allows these functions to be used
internally without clobbering the errno value. From Freddie Chopin
(2016-11-09).
* arch/arm/src/stm32l4: Change the way to configure quadrature encoder
prescalers. From Sebastien Lorquet (2016-11-09).
* libc/unisted: Patch brings strtol() and related functions more
conformant with POSIX. Corner cases like strtol(-2147483648, NULL, 10)
now pass clang -fsanitize=integer without warnings. From Juha Niskanen
(2016-11-10).
* drivers/sensors and configs/stm32f103-minimum: Add Vishay VEML6070
driver and support for STM32F103-Minimum board. From From Alan
Carvalho de Assis(2016-11-13).
* Misoc LM32: Corrects a bug that never occured in qemu on simulation or
real fpga. The error was that the r1 register was being modified out of
context switching and not restoring it. From Ramtin Amin (2016-11-14)
* arch/arm/src/samv71: A problem occurred with the SAMV7 USBDEVHS driver
if the USB cable is unplugged while a large amount of data is send over
an IN endpoint using DMA. If the USB cable is plugged in again after a
few seconds it is not possible to send data over this IN endpoint again,
all other endpoints work as expected.
The problem occurs because if the USB cable is unplugged while an DMA
transfer is in flight the transfer is canceled but the register
SAM_USBHS_DEVDMACTRL is left in an undefined state. The problem was
fixed the problem by resetting the register SAM_USBHS_DEVDMACTRL to a
known state. Additionally all pending interrupts are cleared.
From Stefan Kolb (2016-11-14).
* configs/esp32-core: ESP32 Core v2: Add configuration to supporting
linking NuttX for execution out of IRAM (2016-11-14).
* libc/unistd: sleep() was returning remaining nanoseconds (kind of),
instead the remaining seconds. From Eunbong Song (2016-11-15).
* sched/irq: Fixes for the SMP case: (1) Change order for SMP case in
enter_critical_section: (1) Disable local interrupts BEFORE taking
spinlock and (2) If SMP is enabled, if any interrupt handler calls
enter_critical_section(), it should take the spinlock. (2016-11-15).
* arch/xtensa: Add EXPERIMENTAL hooks to support lazy Xtensa co-
processor state restore in the future (2016-11-16).
* Add some experimental changes to enter/leave_critical_section to
deal with the case where interrupts are disabled only on the local
CPU (2016-11-16).
* sched/irq: Add logic to handled nested calls to
enter_critical_section() from interrupts handlers (with SMP)
(2016-11-16).
* drivers/timer: Remove the timer driver TIOC_SETHANDLER IOCTL call.
This calls directly from the timer driver into application code. That
is non-standard, non-portable, and cannot be supported (2016-11-17).
*drivers/timer: Add timer driver hooks to support signal notification
of timer expiration. Commented out because invasive interface changes
would also be required to complete the implementation (2016-11-17).
* arch/arm/src/armv7-m: Fix double allocation of MPU region in mmu.h
(2016-11-17).
* timer driver: Use signal to notify of timer expiration. Add generic
argument so that there can be additional usage. From Sebastien Lorquet
(2016-11-17).
* All timer lower half drivers. Port Sebastien's changes to all all
other implementations of the timer lower half. Very many just and
untested. Expect some problems. (2016-11-17).
* sched/irq: irq_csection() has a bad assumption in the SMP case. It
assumed that the state of certain variables. That was true on entry
into the interrupt handler, but might change to the execution of logic
within the interrupt handler (2016-11-18).
* config/ nucleo-l476rg: Add support for timers to nucleo l476. From
Sebastien Lorquet (2016-11-18).
* drivers/net: Add option to use low-priority work queue to all drivers
in drivers/net. Not yet added to all architecture-specific network
drivers (2016-11-18).
* sched/wdog: Most interrupt handling logic interacts with tasks via
standard mechanism such as sem_post, sigqueue, mq_send, etc. These all
call enter_critical_section and are assumed to be safe in the SMP case.
But certain logic interacts with tasks in different ways. The only one
that comes to mind are wdogs. There is a tasking interface that to
manipulate wdogs, and a different interface in the timer interrupt
handling logic to manage wdog expirations.
In the normal case, this is fine. Since the tasking level code calls
enter_critical_section, interrupts are disabled an no conflicts can
occur. But that may not be the case in the SMP case. Most
architectures do not permit disabling interrupts on other CPUs so
enter_critical_section must work differently: Locks are required to
protect code.
So this change adds locking (via enter_critical section) to wdog
expiration logic for the the case if the SMP configuration
(2016-11-18).
