NuttX-7.21 Release Notes
------------------------
The 121st release of NuttX, Version 7.21, was made on June 6, 2017,
and is available for download from the Bitbucket.org website. Note
that release consists of two tarballs: nuttx-7.21.tar.gz and
apps-7.21.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:
- pthread rwlocks: Add an implementation for read/write locks
(rwlocks) into the pthread library. These locks are writer
priority, such that if any writers come in they are given priority
for writing. From Mark Schulte.
- pthread robust mutexes: Implement robust mutex support:
pthread_mutex_lock() and trylock() will return EOWNERDEAD if the
mutex is locked by a thread that no longer exists. Add
pthread_mutex_consistent() to recover from this situation. Keep
list of all mutexes held by a thread in a list in the pthread's TCB.
When pthread exits or is cancelled, mutexes held by thread are
marked inconsistent and the highest priority thread waiting for the
mutex is awakened. There is a configuration option to (a) support
only robust mutexes, (b) support only traditional unsafe mutexes,
or (c) Support both unsafe and robust mutexes via
pthread_mutexattr_get/setrobust().
- pthread cancellation points: Add logic to disable cancellation
points within the OS. This is useful when an internal OS function
that is NOT a cancellation point calls an OS function which is a
cancellation point. In that case, irrecoverable states may occur if
the cancellation is within the OS. From Juha Niskanen.
- clock: Add clock_resynchronize and use subseconds RTC. Add
clock_resynchronize for better synchronization of CLOCK_REALTIME and
CLOCK_MONOTONIC to match RTC after resume from low-power state. Add
up_rtc_getdatetime_with_subseconds under
CONFIG_ARCH_HAVE_RTC_SUBSECONDS to allow initializing (and
resynchronizing) system clock with subseconds accuracy RTC. From
Jussi Kivilinna.
- clock: Add new type ssystime_t for relative 64-bit ticks, change
ticks<->time conversion functions to use ssystime_t. From Jussi
Kivilinna.
- clock: Add testing for 32-bit overflow of 64-bit system timer. From
Jussi Kivilinna.
* File Systems/Block and MTD Drivers
- drivers/mtd/w25.c: Erase sector only if it is not in erased state.
From Jussi Kivilinna.
* Graphics/Display Drivers:
- drivers/lcd: Extend st7565 driver to include support for the
AQM_1248A. From Masayuki Ishikawa.
- drivers/lcd: Add driver for Nokia 5110 (Philips PCD8544). From Alan
Carvalho de Assis.
* Networking/Network Drivers:
- Extensive modifications to support wireless network (see below).
- TUN driver: Implement TAP (OSI layer 2) mode. Enable by setting the
IFF_TAP flag instead of the IFF_TUN flag in ifr_flags. From Thomas
Keh.
- Add user-space networking stack API (usrsock). User-space
networking stack API allows user-space daemon to provide TCP/IP
stack implementation for NuttX network. Main use for this is to
allow use and seamless integration of HW-provided TCP/IP stacks to
NuttX. For example, user-space daemon can translate /dev/usrsock
API requests to HW TCP/IP API requests while rest of the user-space
can access standard socket API, with socket descriptors that can be
used with NuttX system calls. From Jussi Kivilinna.
- net/: Network driver now retains Ethernet MAC address in a union so
that other link layer addresses may be used in a MULTILINK
environment.
* Wireless Networking/Wireless Drivers:
- BCM43362: Support for Broadcom's BCM43362 WiFi chip was contributed
by Simon Piriou as part of the port of the Particle Photon board.
Only station functionality is available at present. This work
includes not on the WiFi driver, but the support Particle Photon
board, the infrasture for IEEE 802.11 FullMAC networking including
the network device interface, WiFi configuration, AP scanning and
authentication and association with an AP.
- IEEE 802.11 networking tools and support.
- IEEE 802.15.4 MAC support. This is an effort that was started some
time back by Sebastien Lorquet (with some help from Matte Poppe).
Recently, Anthony Merlino has taken on this effort and has made
some significant progress. Using the Microchip MRF24J40 module with
the Mikroe Clicker2-STM32 board along with a PC-based IEEE 802.15.4
sniffer, Anthonly has verified correct transmittion and receipt of
basic frames.
- Microchip MRF24J40: As mentioned above, this IEEE 802.15.4 radio
driver is now basically functional.
- IEEE 802.15.4 Network Driver: A driver that interfaces the NuttX
network with the IEEE 802.15.4 MAC has been developed but is still
incomplete and has not been verified.
- IEEE 802.15.4 Network Loopback Driver: A simple IEEE 802.15.4 MAC
loopback driver was developed. This driver allowed for parallel
development of the IEEE 802.15.4 MAC and 6loWPAN.
- 6loWPAN: The Contiki 6loWPAN stack has been ported so that works
within the NuttX networking framework and interfaces with the new
IEEE 802.15.4 MAC via the network driver. Live testing with
IEEE 802.15.4 radios has not yet been done; all testing has used
the loopback driver. There are no known problems and the stack
is ready for additional testing.
- Add option to enable wireless debug output.
* Other Common Device Drivers:
- Add entropy pool and strong random number generator. Entropy pool
gathers environmental noise from device drivers, user-space, etc.,
and returns good random numbers, suitable for cryptographic use.
Based on entropy pool design from *BSDs and uses BLAKE2Xs algorithm
for CSPRNG output. Patch also adds /dev/urandom support for using
entropy pool RNG and new 'getrandom' system call for getting
randomness without file-descriptor usage (thus avoiding file-
descriptor exhaustion attacks). The 'getrandom' interface is similar
as 'getentropy' and 'getrandom' available on OpenBSD and Linux
respectively. From Jussi Kivilinna.
- XBox One controller: Adds USB host driver support for the XBox One
controller. Currently only the latest version (XBox One X)
controller works. The older XBox One controllers do not enumerate
correctly. From Brian Webb.
- drivers/analog: Add basic COMP driver. From Mateusz Szafoni.
- drivers/analog: Add driver for the LTC1767L ADC. From Martin
Lederhilger.
- drivers/analog: Add basic OPAMP driver. From Mateusz Szafoni.
- drivers/sensors: Add driver for ST HTS221 humidity sensor. From
Juha Niskanen.
- drivers/sensors: Add driver for ST LPS25H pressure sensor. From
Juha Niskanen.
- drivers/sensors: Add driver for ST LIS2DH accelerometer. From Timo
Voutilainen.
- drivers/usbmisc: Add driver for Fairchild FUSB301 USB type-C
controller. From Harri Luhtala.
- RTC: Add interface for check if RTC time has been set. New
interface allows checking if RTC time has been set. This allows to
application to detect if RTC has valid time (after reset) or should
application attempt to get real time by other means (for example, by
launching ntpclient or GPS). From Jussi Kivilinna.
- Buttons: Change return value of board_buttons() and the type of
btn_buttonset_t to uint32_t so that more than 8 buttons can be
supported.
- drivers/syslog: Use monotonic clock for timestamp when available.
From Jussi Kivilinna.
- SPI: Add an instance argument to the SPIDEV definitions. Thus,
instead of specifying a FLASH device, for example, as SPI_FLASH, you
would now use SPI_FLASH(0) where the "instance" argument now
distinguishes multiple FLASH devices on the same SPI bus. From
Sebastien Lorquet.
- IOBs: Move from net/iob to a better location in mm/iob where they
can be shared outside of the networking logic. Current also used
by IEEE 802.15.4 MAC and by syslog (when buffering enabled).
- syslog: Add option to buffer SYSLOG output to avoid interleaving.
Uses new shareable IOBs. Additional logic to assure that the the
write from the buffer is a single atomic write in normal debug
output.
- drivers/can: Move CAN subsystem to its own directory and put device
drivers there. From Alan Carvalho de Assis.
- drivers/can: Add Microchip MCP2515 CAN Bus controller driver. From
Alan Carvalho de Assis.
- drivers/audio: Add cs43l22 audio driver. From Taras Drozdovsky.
- drivers/input: Add Cypress MBR3108 CapSense touch button driver.

C++ std namespace. From Alan Carvalho de Assis.
- C Library: Add ffsl(), ffsll(), fls(), flsl(), flsll() and use
GCC's __builtin_ctz/__builtin_clz for faster implementation of these.
From Jussi Kivilinna.
- fixedmath: Add square root and b32_t conversion operators. From
Jussi Kivilinna.
- locale.h: Add a bogus definition of locale_t.
- C library: Versions mbrlen and mbsrtowcs taken and adapted from
FreeBSD code (at https://github.com/freebsd/freebsd/). From Matias
v01d.
* Build/Configuration System:
- Include C++ library in 'make export'. From Alan Carvalho de Assis.
- configs: Remove all setenv.sh and setenv.bat files. Remove all
references to setenv.sh and setenv.bat from all config README files.
- Kconfig/deconfigs: Add CONFIG_ARCH_TOOLCHAIN_GNU to indicate that
the toolchain is based on GNU gcc/as/ld. This is in addition to the
CPU-specific versions of the same definition.
- Move prototype for up_cxxinitialize() from nuttx/include/nuttx/arch.h
to apps/include/platform/cxxinitialize.h.
* Tools:
- Add initialconfig.c so that perhaps in the future we will be able to
use this to generate a new configuration from scratch (rather than
having to derive new configurations from existing configurations).
NOTE: Not yet intregated into the build system.
* NSH: apps/nshlib:
- Added support for set [{+|-}{e|x|xe|ex}] [<name> <value>]. Set the
'exit on error control' and/or 'print a trace' of commands when
parsing scripts in NSH. The settinngs are in effect from the point
of exection, until they are changed again, or in the case of the init
script, the settings are returned to the default settings when it
exits. Included child scripts will run with the parents settings and
changes made in the child script will effect the parent on return.
Use 'set -e' to enable and 'set +e' to disable (ignore) the exit
condition on commands. The default is -e. Errors cause script to
exit. Use 'set -x' to enable and 'set +x' to disable (silence)
printing a trace of the script commands as they are ececuted. The
default is +x. No printing of a trace of script commands as they are
executed. From David Sidrane.
- Print expanded variables if -x. From David Sidrane.
- ifconfig command: Extend ifconfig to support 6loWPAN. Adapt to
some changes in configuration variable usage.
- Network initialization: If IEEE802.11 selected use wlan0 instead of
eth0 for network device name.
- Network initialization: NSH now has configuration options to select
the wireless properties. It builds the configuration structure and
passes this to wpa_driver_wext_associate() so that it will set the
network as configured.
- Network initialization: Add a new option CONFIG_NSH_NETLOCAL that
will suppress some built in operations and will support manual
configuration of a wireless network through command line tools.
* Examples/Tests: apps/examples:
- examples/xbc_text: Adds a test program for the XBox One controller
driver. From Brian Webb.
- examples/ostest: Add a test of robust mutexes.

6loWPAN node address.
- netlib and NSH: Add logic to get/set the IEEE802.15.4 PAN ID.
- netutils/dhcpc: Make the network device name a configuration
option. Was hardcoded to eth0 but may, instead, need to be wlan0.
- netutils/dhcpc: Remove hard-coded interface device. Now passed as
a parameter to dhcpc_open(). From Sebastien Lorquet.
* Wireless Utilies: apps/wireless:
- wireless/wapi: Port of Wapi wireless services. The original
depended on features not supported by NuttX: Removed logic that
depends on Linux netlink. Removed functionality that depended on
the Linux procfs: This includes only 1) listing of available
interfaces and 2) listing of all routes.
- wireless/wapi: Create command line Wapi application based on
Wapi sample code.
- wireless/wapi: wpa_driver_wext_associate() now accepts a
configuration parameter that can be used to specify the wireless
properties.
- wireless/wapi: Add basic wapi_event_stream_extract implementation.
From Simon Piriou.
- wireless/ieee802154: Add iwpan and i8sak tools. iwpan is similar
in concept to wapi. From Anthony Merlino (i8sak was originally
by Sebastien Lorquet).
- wireless/ieee802154/libmac: IEEE 802.15.4 MAC library.
- wireless/wext: Add drivers_wext from the WPA supplicant; Integrate

- apps/system/ramtest: Make stacksize and priority conigurable.
* Platform-Specific Support (apps/platform)
- apps/platform: Create gnu/ subdirectory that contains the one and
only GNU C++ initialization function. Remove all other C++
initialization functions.
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:
- Priority inheritance: When CONFIG_SEM_PREALLOCHOLDERS==0, there is
only a single, hard-allocated holder structure. This is problem
because in sem_wait() the holder is released, but needs to remain in
the holder container until sem_restorebaseprio() is called. The call
to sem_restorebaseprio() must be one of the last things the
sem_wait() does because it can cause the task to be suspended. If in
sem_wait(), a new task gets the semaphore count then it will fail to
allocate the holder and will not participate in priority
inheritance. This fix is to add two hard-allocated holders in the
sem_t structure: One of the old holder and one for the new holder.
- Priority inheritance: sem_holder sem_findholder missing
inintalization of pholder. sem_findholder would fail and code
optimization covered this up. From David Sidrane.
- Partial Fix priority inheritance CONFIG_SEM_PREALLOCHOLDERS=0. From
David Sidrane.
- Priority inheritance: sem_boostholderprio prevent overrun of
pend_reprios. The second case rtcb->sched_priority <=
htcb->sched_priority did not check if there is sufficient space in
the pend_reprios array. From David Sidrane.
- lp_worker: Guard from pend_reprios overlow. From David Sidrane.
- Priority inheritance: Fixes improper restoration of base_priority in
the case of CONFIG_SEM_PREALLOCHOLDERS=0. The call to
sem_restorebaseprio_task context switches in the
sem_foreachholder(sem, sem_restoreholderprioB, stcb); call prior to
releasing the holder. So the running task is left as a holder as is
the started task. Leaving both slots filled thus failing to perform
the boost/or restoration on the correct tcb. This PR fixes this by
releasing the running task slot prior to reprioritization that can
lead to the context switch. To faclitate this, the interface to
sem_restorebaseprio needed to take the tcb from the holder prior to
the holder being freed. In the failure case where sched_verifytcb
fails it added the overhead of looking up the holder. There is also
the additional thunking on the foreach to get from holer to
holder->tcb. An alternate approach could be to leve the interface
the same and allocate a holder on the stack of sem_restoreholderprioB
copy the sem's holder to it, free it as is done in this pr and and
then pass that address sem_restoreholderprio as the holder. It could
then get the holder's tcb but we would keep the same sem_findholder
in sched_verifytcb. From David Sidrane.
- Priority inheritance: Fixes improper restoration of base_priority.
From David Sidrane.
- sem_holder: Indexing error. From David Sidrane.
if (sem->holder[0].htcb != NULL || sem->holder[**1**].htcb != NULL)
- realloc(): When realloc() has to fall back to calling malloc(), size
including overhead was being provided to malloc(), causing a slightly
larger allocation than needed. Noted by initialkjc@yahoo.com.

- There can be a failure in IOB allocation to some asynchronous
behavior caused by the use of sem_post(). Consider this scenario:
(1) Task A holds an IOB.  There are no further IOBs.  The value of
semcount is zero. Task B calls iob_alloc().  Since there are not
IOBs, it calls sem_wait().  The value of semcount is now -1. (2)
Task A frees the IOB.  iob_free() adds the IOB to the free list and
calls sem_post() this makes Task B ready to run and sets semcount to
zero NOT 1.  There is one IOB in the free list and semcount is zero.
When Task B wakes up it would increment the sem_count back to the
correct value. (3) But an interrupt or another task runs occurs
before Task B executes.  The interrupt or other tak takes the IOB off
of the free list and decrements the semcount.  But since semcount is
then < 0, this causes the assertion because that is an invalid state
in the interrupt handler. So I think that the root cause is that
there the asynchrony between incrementing the semcount. This change
separates the list of IOBs: Currently there is only a free list of
IOBs. The problem, I believe, is because of asynchronies due
sem_post() post cause the semcount and the list content to become out
of sync. This change adds a new 'committed' list: When there is a
task waiting for an IOB, it will go into the committed list rather
than the free list before the semaphore is posted. On the waiting
side, when awakened from the semaphore wait, it will expect to find
its IOB in the committed list, rather than free list. In this way,
the content of the free list and the value of the semaphore count
always remain in sync.
- binfmt: Fix .dtor memory allocation. From Masayuki Ishikawa.
* File System/Block and MTD Drivers:
- SmartFS: If whence is SEEK_END, the file offset shall be set to the
size of the file plus offset. Noted by eunb.song@samsung.com.
- mtd/progmem: Fix incorrect target address calculation.
progmem_read/write() is incorrectly calculating the target address,
expecting the offset argument is given in a block number. This is
completely wrong and as a result invalid flash region is accessed.
Byte-oriented read/write interfaces of mtd device accept the target
address in a byte offset, not a block number. From Heesub Shin.
- procfs: Fix wrong member IDs are displayed when 'cat
/proc/<pid>/group/status'. From Nobutaka Toyoshima.
- procfs: Fix incorrect uptime with CONFIG_SYSTEM_TIME64. From
Masayuki Ishikawa.
- vfs/poll: round timeout up to next full tick. Calling poll() with
timeout less than half tick (thus MSEC2TICK(timeout) => 0) caused
returning error with EAGAIN. Instead of rounding timeout down, value
should be rounded up. Open Group spec for poll says:
"Implementations may place limitations on the granularity of timeout
intervals. If the requested timeout interval requires a finer
granularity than the implementation supports, the actual timeout
interval will be rounded up to the next supported value." From Jussi
Kivilinna.

ftl_initialize() in some configurations. Also fixes related assert:
up_assert: Assertion failed at file:rwbuffer.c line: 643
that can happen with the following configuration:
CONFIG_FTL_WRITEBUFFER=y
CONFIG_DRVR_WRITEBUFFER=y
# CONFIG_FS_WRITABLE is not set
These problems are caused by CONFIG variable differences between the
buffer layers. TODO: This is not a perfect solution. readahead

From Masayuki Ishikawa.
- FAT: Fix 'Missing unlock' in fs_fat32.c. From Masayuki Ishikawa.

more clean-up.
- IPv6: Fix net_ipv6_pref2mask(). From Masayuki Ishikawa.
- network IOCTL commands: The only place in net/netdev/netdev_ioctl.c
where the interface state should change is for SIOCSIFFLAGS. The
other ones .. SIOCSIFADDR, SIOSLIFADDR, SIODIFADDR .. should not
change the link state. From Sebastien Lorquet.
- TCP: Fix tcp_findlistner() in dual stack mode. From Masayuki
Ishikawa.
* Common Drivers:
- Fix as5048b by adding missing frequency parameter. From Andreas
Bihlmaier.
- multiple fixes in nrf24l01 driver: (1) signal POLLIN if there is
already data in the FIFO, (2) send ETIMEDOUT to userspace after 2
seconds if TX IRQ was not received, (3) handle FIFO overflow, (4)
handle invalid pipes/empty FIFO, and (5) multiple cosmetics (missing
static, duplicate define, missing \n). From Leif Jakob.
- input/mxt: Prevent overriding i2c transfer return value.
put_reg/get_reg function was overriding i2c transfer error code with
i2creset return value, that lead to OK status although actual
transfer failed. From Juha Niskanen.

- drivers/serial: I discovered a problem in the file
drivers/serial/serial.c concerning the function uart_close(…). In the
case that a serial device is opened with the flag O_NONBLOCK the
function uart_close(…) blocks until all data in the buffer is
transmitted. The function close(…) called on an handle opened with
O_NONBLOCK should not block. The problem occurred with a CDC/ACM
device. From Stefan Kolb.

- CONFIG_DEBUG_HARDFAULT should be available for Cortex-M0 too.
* Microchip/Atmel SAM3/4 Drivers:
- SAM3/4: Fixed configurations for TWI master. Obviously an
incomplete port from SAMA5.
* Microchip/Atmel SAMv7 Drivers:
- SAMV7: Watchdog: Fix Forbidden Window Value. According the Datasheet
the WDD Value is the lower bound of a so called Forbidden Window and
to disable this we have to set the WDD Value greater than or equal to
the WDV Value. This seems to be a bug in the datasheet. It looks
like we have to set it to a greater value than the WDV to really
disable this Thing. When triggering the Watchdog faster than the
(very slow) clock source of the Watchdog fires, this Forbidden Window
Feature resets the System if WDD equals to WDV. This Changeset
disables the Forbidden Window by setting the WDD Value to the Maximum
(0xfff) Value possible. From Frank Benkert.
- SAMV7 EMAC: Add conditional logic to account the fact that the

Bihlmaier.
* Silicon Labs EFM32 Drivers:
- EFM32 I2C: Fix timeout calculation. From Masayuki Ishikawa.
* STMicro STM32:
- As discovered by dcabecinhas. This fix assume the 8 byte alignment
options for size stack size or this will overwrite the first word
after TOS. See
https://github.com/PX4/Firmware/issues/6613#issuecomment-285869778.
From David Sidrane.
- STM32 F7: In stm32_allocateheap.c There are 5 not 4 configurations.
From David Sidrane.
* STMicro STM32 Drivers:
- STM32, STM32 F7, STM32 L4: OTG host drivers: Do not do data toggle
if interrupt transfer is NAKed. Sugested by webbbn@gmail.com.
- Save elapsed time before handling I2C in stm32_i2c_sem_waitstop().
This change follows the same logic as in previous fix to
stm32_i2c_sem_waitdone(). It is possible that a context switch
occurs after I2C registers are read but before elapsed time is saved
in stm32_i2c_sem_waitstop(). It is then possible that the registers
were read only once with "elapsed time" equal 0. When scheduler
resumes this thread it is quite possible that now "elapsed time" will
be well above timeout threshold. In that case the function returns
and reports a timeout, even though the registers were not read
"recently". Fix this by inverting the order of operations in the loop
- save elapsed time before reading registers. This way a context
switch anywhere in the loop will not cause an erroneous "timeout"
error. From Freddie Chopin.
- STM32, STM32 F7, and STM32 L4: Clone Freddie Chopin's I2C change to
similar STM32 I2C drivers. From David Sidrane.
- STM32: OTG host implementations of stm32_in_transfer() must obey the
polling interval for the case of isochronous and interrupt endpoints.
- STM32: Fix erase sector number for microcontrolers with more than 11
sectors. Erase a sector from the second bank cause the bit 4 of SNB
being set but never unsed, so trying to erase a sector from the first
bank was acually eraseing a sector from the second bank. From José
Roberto de Souza.
- STM32: Make up_progmem thread safe. Writing to a flash sector while
starting the erase of other sector have a undefined behavior so lets
add a semaphore and syncronize access to Flash registers. But for
the semaphore to work it needs to be initialized so each board needs
call stm32_flash_initialize() on initialization, so to avoid runtime
problems it is only using semaphore and making it thread safe if
initialized, after all boards starts to call stm32_flash_initialize()
we can remove the boolean and the check. From José Roberto de Souza.
- STM32: Add workaround for flash data cache corruption on
read-while-write. This is a known hardware issue on some STM32 see
the errata of your model and if you make use of both memory banks you
should enable it. From José Roberto de Souza.
- STM32 Flash fixes. From José Roberto de Souza.
- STM32 Flash: Missing unlock on F1 HSI off path. From David Sidrane.
- STM32 F4 I2C: I needed to use DS3231, I remember that in past it
worked ok, but now for stm32f4xx is used another driver (chip
specific, stm32f40xxx_i2c.c) and DS3231 driver doesn't work. After
investigating a problem I found that I2C driver (isr routine) has a
few places there it sends stop bit even if not all messages are
managed. So, e.g., removing stm32_i2c_sendstop (#1744) and adding
stm32_i2c_sendstart after data reading helps to make DS3231 working.
From Alexander Oryshchenko; verified by David Sidrane.
- STM32 F7 Serial: Serial fix for dropped data: (1) Revert the
inherited dma bug from the stm32. see
https://bitbucket.org/nuttx/nuttx/commits/df9ae3c13fc2fff2c21ebdb098c520b11f43280d
for details. And (2) Most all CR1-CR3 settings can not be configured
while UE is true. Threfore we make all operation atomic and disable
UE and restore it's originalstate on exit. From David Sidrane.
- STM32 L1: Fix IWDG and WWDG debug mode stop for STM32L15XX. From
Juha Niskanen.
- STM32 F7: Fix UART7 and UART8 IFLOWCONTROL options. From Jussi
Kivilinna.
- STM32 F7: Add warning for RXDMA + IFLOWCONTROL combination.
Combination of RXDMA + IFLOWCONTROL does not work as one might
expect. Since RXDMA uses circular DMA-buffer, DMA will always keep
reading new data from USART peripheral even if DMA buffer underruns.
Thus this combination only does following: RTS is asserted on USART
setup and deasserted on shutdown and does not perform actual RTS
flow-control. Data loss can be demonstrated by doing long up_mdelay
inside irq critical section and feeding data to RXDMA+IFLOWCONTROL
UART. From Jussi Kivilinna.
- STM32 F7 Serial: Do not stop processing input in SW flow-control
mode. From Jussi Kivilinna.
- STM32 L4 DMA: Correct bad channel definition. From Sebastien Lorquet.
- STM32 F7: Warn if no DMA2 configured when using ADC with DMA. Also
correct ADC channel numbers that DMA callback passes to upper half
driver. From Juha Niskanen.
- STM32 F7 ADC: Do not override ADCPRE_DIV when measuring
internal voltage. From Juha Niskanen.
- STM32 L4: Don't think these chips have DPFPU, DTCM or ITCM. From
Juha Niskanen.
- STM32 F7 Flash: macro naming errors, there is no FLASH_CONFIG_F for
F7. From Juha Niskanen.
- STM32 L4: stm32l4x6xx_pinmap: Update I2C4 and DCMI pins. From Juha
Niskanen.
- STM32 L4: stm32l4_i2c: change wrong macro to CONFIG_I2C_POLLED. From
Juha Niskanen.
- Fix STM32F7 I2C interrupt handler. From Jussi Kivilinna.
- STM32: Serial Allow configuring Rx DMA buffer size. From David
Sidrane.
- STM32 CAN: I had the problem that the transmit FIFO size (= actual
elements in FIFO) was slowly increasing over time, and was full after
a few hours. The reason was that the code hit the line
"canerr("ERROR: No available mailbox\n");" in stm32_cansend, so
can_xmit thinks it has sent the packet to the hardware, but actually
has not. Therefore the transmit interrupt never happens which would
call can_txdone, and so the size of the FIFO size does not decrease.
The reason why the code actually hit the mentioned line above, is
because stm32can_txready uses a different (incomplete) condition than
stm32can_send to determine if the mailbox can be used for sending,
and thus can_xmit forwards the packet to stm32can_send.
stm32can_txready considered mailboxes OK for sending if the mailbox
was empty, but did not consider that mailboxes may not yet be used if
the request completed bit is set - stm32can_txinterrupt has to
process these mailboxes first. Note that I have also modified
stm32can_txinterrupt - I removed the if condition, because the CAN
controller retries to send the packet until it succeeds. Also if the
condition would not evaluate to true, can_txdone would not be called
and the FIFO size would not decrease also. From Lederhilger Martin.
- STM32 Serial: Fix freezing serial port. Serial interrupt
enable/disable functions do not disable interrupts and can freeze
device when serial interrupt is received while execution is at those
functions. Trivially triggered with two or more threads write to
regular syslog stream and to emergency stream. In this case, freeze
happens because of mismatch of priv->ie (TXEIE == 0) and actually
enabled interrupts in USART registers (TXEIE == 1), which leads to
unhandled TXE interrupt and causes interrupt storm for USART. From
Jussi Kivilinna.
- STM32 I2C: Make private symbols static. From Juha Niskanen.
- STM32 L4 GPIO: Put back EXTI line source selection. From Juha
Niskanen.
- STM32 L4 RTC: Store RTC MAGIC to backup reg, not to address zero.

* Tools
- Fix mksyscall host binary name. From Alan Carvalho de Assis.
* Applications (apps/)
- Fix some calls to task_create(): argv[0] is the first parameter, not
the name of the task.
- Bitbucket Issue 5: I found an unexpected behavior in apps/
configuration generation. Adding external symbolic link in apps/
directory and using Make.defs for Kconfig generation, Kconfig file
has a wrong path in the source argument. It contains original dir
path outside of the source tree instead path to sub-directory in
apps/. The problem is connected with make/system symbolic link path
resolution. Corrected by a patch submitted by Artur Madrzak with
Issue 5.
- apps/: Make more globals static to avoid name clashes. From Juha
Niskanen.
* NSH: apps/nshlib:
- NSH library: In nsh_argexand(), if CONFIG_NSH_ARGCAT is defined but
CONFIG_NSH_CMDPARMS defined and/or CONFIG_DISABLE_ENVIRON not
defined, then there is a situation that causes an infinite loop in
the parser. Noted by Freddie Chopin.
- NSH library: Fix building when CONFIG_NET_USRSOCK enabled with other
link-layers. From Jussi Kivilinna.
- NSH library: Fix some warnings about integer/pointer casts of
different sizes (probably only effects 64-bit simulation).
- NSH library: Fix open flags in nsh_codeccmd.c. From Masayuki
Ishikawa.
- I need to look at the registers that are at or around 0xe000ef90.
Using mw and xd, I see that nsh does not support pointers greater
than 0x7fffffff. A quick look at the source shows that the pointers
for those two commands are set with calls to strtol() rather than
strtoul(). Changing the two pointer-setting instances to strtoul()
fixes the problem, at least for my architecture/config. From Ian
McAfee.
- NSH library: Fix a resource leak in cmd_hexdump(). From Nobutaka
Toyoshima.
* Examples/Tests: apps/examples:
- apps/examples/hidkbd: Remove call to arch_usbhost_initialize().
That is violation of the OS interfacing rules and will no longer be
supported. USB host should be initialized as part of the normal
board bring-up logic as with any other devices and should not involve
illegal calls from applications into the OS.
- apps/examples/usbterm: Removed because it is not very useful and
because it can be configured to use an illegal call into the OS.
- examples/mm: Fix Makefile. Built-in was not being registered.
- examples/hidkbd: Add some missing configuration settings.
- examples/random: Avoid stack overflows. From Juha Niskanen.
- examples/nettest: Fix an error in pre-processor expression.
- examples/mtdpart: Prevent part array overflow. mtdpart examples
create partions and allocate from 1 index not a 0 index to part[]
array. This cause buffer overflow for part array. This change fixes
this problem. From EunBong Song.
- examples/can: Fix can example app to print data when
CONFIG_EXAMPLE_CAN_READ is defined. From Alan Carvalho de Assis.
* Network Utilies: apps/netuils:
- Not a clean fix, but at least makes DHCP working with
CONFIG_NETDEV_MULTINIC. From Andreas Bihlmaier.
- Ensure netlib will not be broken when setip will not bring the
network up anymore. From Sebastien Lorquet.
* CAN Utilies: apps/canutils:

From Alan Carvalho de Assis.
- Fix to use the new canardInit() function. From Alan Carvalho de
Assis.
* System Unitilities (apps/system)
- system/dhcpc: Add missing argument of fprintf.
* Tools (apps/tools):
- The dedicated windows tool at tools/mkkconfig.bat uses $APPSDIR,
which is not a windows shell variable, and is left uninitialized, but
in fact should be the current directory. From Sebastien Lorquet.
