Gregory Nutt
committed
* drivers/usbdev/Kconfig, usbmsc.c, usbmsc.h, and usbmsc_scsi.c:
Redesign threading module used with the USB MSC driver. It was using
pthreads before and these were changed to a kernel thread. The reason
for this has to do with task grouping: A pthread is a memory of the
group of the task that started it. A kernel thread is independent of
the task that started in (other than knowing it as the parent). This
allows me to remove so kludge logic to "deparent" the pthread on
startup (2014-3-25).

* configs/sama5d*/include/board.h, board_sdram.h, and other files:
When booting from SDRAM, we need to query the PMC registers (using

* Many files: Convert all old-style variadic macros to the C99 form.
Recent GCC changes tightens up that behavior and can cause some problems
(at least for the IAR compiler for some reason). See
https://gcc.gnu.org/onlinedocs/cpp/Variadic-Macros.html#Variadic-Macros.

freed. From Max Holtzberg (2014-6-2).
* TCP fallback allocation: Added all states in which the connections are
about to be closed. Fallback mechanism is disabled when SO_LINGER is
enabled to prevent deadlocks in netclose_disconnect(). From Max Holtzberg

files is seen as a bug in javascript and images. From Max/Himax
(2014-6-19).

for the lpcxpresso's rtc handler, adc, dac, timers, pwm and mcpwm
drivers. From Max (himax) (2014-6-23).
* net/tcp/Kconfig: Cannot enable bother TCP write buffering AND raw
packet sockets. This should not logically be the case, but is because
the implementations are presently too coupled. The logic packet
socket logic in net/net_send_unbuffered.c needs to be broken out into
a separate file so that write buffered TCP and packet socket transfers
can co-exist (2014-6-23).
* net/uip/uip_pktsend.c: Move the logic that copies data into the
device buffer from net/net_send_unbuffered.c to net/uip/uip_pktsend.c.
This makes the packet socket design more consistent with TCP and UDP

* net/: Separate net/net_send_buffered.c and net/net_send_unbuffered.c
to net/tcp/tcp_send_buffered.c, net/tcp/tcp_send_unbuffered.c, and

remove duplicates. Add support for the STM32F103RC and RD. From
Kosma Moczek (2014-6-30)
* configs/sam4s-xplained-pro: Correct description of LEDs and
usage. From Kosma Moczek (2014-6-30)
* include/unistd.h: Some POSIX_* and _POSIX_* macros are defined
without value, whereas (as far as I can tell) the newer versions
of the standard require them to have the value corresponding to
the standard version implemented, like 200809L. Are the any plans
to clean this up? For now I've put together a quick patch that
defines those macros to 1, consistent with the rest of unistd.h.
From Kosma Moczek (2014-6-30)
* arch/arm/src/sama5/sam_memories.c: Fix some logic in conversion
of physical and virtual DRAM addresses when running out of DRAM. This
is an important bug fix for the SAMA5D3 and 4 when running out of
DRAM (2014-6-30).
* arch/arm/src/sama5/sam_pio.c: Another *critical* SAMA5D3 and 4 bug
fix: PIO clocking must be enabled for all input pins or else the
value that is read never changes. (2014-6-30).
* net/: Many more functions renamed to follow new modularization of
the networking code. This is part of an ongoing repartitioning
effort and there is still more to be done. There will be no additional
notations in this ChangeLog until the renaming is complete (2014-6-30).
* arch/arm/src/sam34/sam_emac.c, sama5/sam_emaca.c, sam_emacb.c, and
sam_gmac.c: Fix cloned error: Wrong bits being cleared before ORing
in new bits (2014-7-1).

was not selected and the SMART sector size was larger than the mt
device's block size (like it would be if using SMARTFS on larger
flash devices). From Ken Pettit (2014-7-3).

debug was enabled (2014-7-4).
* include/nuttx/net/ip.h and ipopt.h: ip.h renamed ipopt.h. Moved
parts of uip.h to net.h. Renamed the rest of uip.h to ip.h. Removed
all includes of uip.h; added includes of ip.h wherever needed.
Tried to fix problems of the now missing sneak inclusions because
uip.h was removed. There are probably a few of these that were
missed! (2014-7-4).
* drivers/input/mxt.c/h and include/nuttx/input/mxt.h: Add very basic
support for the Atmel maXTouch touchscreen controller (2014-7-5).

character (BCH) driver. This allows any block device to be accessed
as an encrypted character device. From Max Nekludov (2014-7-7).
* SAM3/4: Fix compile of sam_aes.c if CONFIG_CRYPTO_AES is defined.
From Max Nekludov (2014-7-7)

could this have worked before? (2014-7-7).
* SAMA5D3/4 PIO Interrupts: Correct a typo in
arch/arm/src/sama5/sam_pio.h that could disable PIO interrupt support
if only PIOE interrupts were enabled (2014-7-7).
* SAMA5D4 PIO Interrupts: Macro SAM_PION_VBASE is not defined for the
SAMA5D4 and must be replaced with a table lookup (2014-7-7).
* configs/sam*: Fix some cloned errors in SAM GPIO interrupt setup
(1014-7-7).
* arch/arm/src/sama5/Kconfig and sam_allocateheap.c: Add a
configuration option to reserve DRAM for a framebuffer when executing
out of DRAM. This optional was available before when executing out of
NOR, but needs to work a little differently in this case (2014-7-7).
* arch/arm/src/sama5/sam_lcd.c and chip/sam_lcdc.h: Adapt the SAMA5D3
LCDC driver to work with the SAMA5D4 which has no hardware cursor

might by hung (2014-7-9).
* arch/arm/src/sama5/sam_pio.c/.h: Add a new interface
sam_pio_forceclk() that can be used to force PIO clocking on. I am
afraid I was too conservative with PIO clocking in the initial design;
this is the price (2014-7-9).
* arch/arm/src/sama5/sam_twi.c: Use sam_pio_forceclk() so that we can
read the current state of an open-drain output in the TWI reset logic
(2014-7-9).
* arch/arm/src/sama5/sam_pio.c/.h: Fix a typo in Schmitt trigger
configuration; Configure pin as a a vanilla input first so that final
pin configuration is more read-able (i.e., easier to debug)
(2014-7-9).
* drivers/input/mxt: The maXTouch driver works! (2014-7-10).

read-ahead or write buffering to any MTD driver (incomplete) (2014-7-11).
* arch/arm/src/lpc17xx/lpc17_ethernet.c: Comment out an assertion that
is reported to fire inappropriately. From Max (2014-7-11).
* drivers/mtd (mostly): Addition rwbuffer interfaces should not be
enabled unless they are needed; if rwbuffer support is enabled, it
should not be unconditionally enabled in SMART and FTL (2014-7-11).
* libnx/nxglib/nxglib_colorcmp.c and include/nuttx/nx/nxglib.h: New
utility to compare two colors (2014-7-11).

the background if the color did not really change (2014-7-11).
* arch/arm/src/sama5/sam_ldc.c and sama5d4-ek/include/board.h: Back
out the delay kludge. The actual fix to the LDC instability was to
drive the LCD at 2xMCK instead of 1xMCK (2013-7-12).
* drivers/input/mxt.c: Fix an error in the state machine (2014-7-12).
* drivers/input/mxt.c: Add thresholding so that "move" reports are not
generated unless there is a significant change in the reported
position (2014-7-12).
* SAMA5D4-EK MXT: The maXTouch should be able to handler an I2C
frequency of 400KHz. Valid interrupts should occur only on the
falling edge of the ~CHG signal (2014-7-12).
* SAMA5D3x-EK: Use larger icons in NxWM configuration instead of
scaling (2014-7-14).
* Graphics: Rename CONFIG_NX_MOUSE to CONFIG_NX_INPUT, then add
CONFIG_NX_XYINPUT_MOUSE and CONFIG_XYINPUT_TOUCHSCREEN (2014-7-16).
* drivers/input/mxt.c: Fix error in threshoold test... backward
logic (2014-7-16).
* graphics/nxconsole/nxcon_scroll.c: Fix scrolling in the NxConsole
for the case of the framebuffer device. In this case, the logic
for clearing the vacated region at the bottom was missing so garbage
up from the last, uncleared line (2014-7-17).
* drivers/audio/wm8904.c/.h and include/nuttx/audio.wm8904.h: Framework
for a WM8904 audio driver. The initial driver check-in is simply Ken
Pettit's VS1053 driver forced to compile with only WM8904 definitions
(2014-7-18).
* configs/sama5d4-ek/src/sam_wm8904.c: Add logic to configure and
initialize the WM8904 audio CODEC (2014-7-17).

(2014-7-22).
* arch/arm/src/stm32/stm32_otgfsdev.c: STM32 OTGFS device: Various
changes to try to reduce that amount of time in interrupts handles and
with interrupts disbled. Needs verification on other platforms. From
Petteri Aimonen (2014-7-22).
* arch/arm/src/sama5/sam_pck.c: Fix a recently introduced typo that was
being masked by some bad conditional compilation (2015=4-7-22).
* drivers/audio/wm8904.c and include/nuttx/audio/wm8904.h: Remove WM8904
driver unused parameters, clean-up comments, remove some kruft in

* audio/Makefile and pcm_decode.c, include/nuttx/audio/pcm_decode.c,
configs/sama5d4-ek/src/sam_wm8904.c and others: Add new framework for
the PCM decoder. It is now a 'front end' for lower-level drivers like
the WM8904 that performs the PCM decoding from end (2014-7-22).
* audio/pcm_decode.c, configs/sama5d4-ek/src/sam_wm8904.c,
drivers/audio/wm8904.c, and include/nuttx/audio/pcm.h: Rename
pcm_decode.h to pcm.h since it will hold more than just decoding
definitions. Fix some porting errors like idbg should auddbg, etc.
Add wav file header and a few low-level wav utilities (2014-7-22).
* audio/pcm_decode.c and include/nuttx/audio/pcm.h: Flesh out a few
more PCM methods, still incomplete. Re-vision PCM structure
definition (2014-7-22).
* configs/sama*: Disable MMC/SD multiblock transfers in all SAMA5D3/4
configurations. I suspect an issue but have not had time to run it
down yet so the easiest thing is simply to disable the feature for
now (2014-7-23).
* drivers/audio/audio_null.c, include/nuttx/audio/audio_null.c, and
configs/sama5d4-ek/src/sam_audio_null.c: Add a NULL audio device that
can be used to simply unit-level testing of audio decoders (2014-7/23).
* audio/pcm_decode.c, include/nuttx/audio/audio.h, and drivers/audio/audio_null.c
and wm8904.c: Add ioctls so that PCM decoder can configure the driver

now enabled in the default configuration (although they have not yet
been fully integrated into the NxWM media player) (2014-7-23).
* configs/sama5d4-ek/nsh/defconfig: Enable the command line media player
in the NSH configuration as well (still does not work, however)
(2014-7-23).
* audio/Kconfig, audio.c, and include/nuttx/audio/audio.h: Add hooks for
fast-forward and rewind needed by CMediaPlayer; add hooks for
equalizer settings needed by the WM8904 (2014-7-24).
* drivers/audio/audio_null.c and wm8904.c: Fix some compile errors when
audio DEBUG is enabled (2014-7-24).
* SAMA5D4-EK NxWM: Configuration refreshed (2014-7-24).
* arch/arm/src/armv7-m/up_initialstate.c: Correct the initial value of
the BASEPRI register. This was apparently never being initialized!
From Max (2014-7-24).
* configs/mbed/src/up_adc.c, up_dac.c, and up_pwm.c and include/board.h:
Port ADC, DAC, and PWM logic from the configs/zkit-arm-1769. From Max
(2014-7-24).
* arch/arm/src/lpc17xx/lpc176x_rtc.c: Eliminate warnings. From Max
(2014-7-24).
* arch/arm/src/lpc17xx/lpc17_pwm.c, lpc17_timer.c, lpc17_dac.c: Mostly
cosmetic updates from Max (2014-7-24).
* arch/arm/src/lpc17xx/lpc17_adc.c and Kconfig : Added burstmode ADC
conversion mode, with CONFIG_ADC_BURSTMODE option in Kconfig. From
Max (2014-7-24).
* arch/arm/src/lpc17xx/lpc17_ethernet.c: Added option to use the kernel
worker thread to do most of the workload with CONFIG_NET_WORKER_THREAD
option in Kconfig. Eliminated a problem with PHY DP83848C : it doesn't
need a specific initialization on mbed. Critical bugfix: From time to
time (after some hours) the Ethernet receiver would lose one receive
interrupt and the IP stack never recover because there is no receive
watchdog as the transmit watchdog. From Max (2013-7-24).
* audio/pcm_decode.c: Add missing audio callback forwarding logic
(2014-7-25).
* arch/arm/armv7-a/l2cc_pl310.h: Move arch/arm/sama5/chip/sam_l2cc.h to
arch/arm/armv7-a/l2cc_pl310.h. Adjust the two corresponding Kconfig
files as well (2014-7-25).
* arch/arm/src/armv7-a/arm_l2cc_pl310.c, l2cc.h, l2cc_pl310.h, Kconfig:
Add initial support for the ARM L2CC-PL310 L2 cache (2014-7-26).
* arch/arm/src/armv7-a/cp15_cacheops.h: Rename ARMv7-A cache.h to
cp15_cache.h. Things will be broken on this commit until I get the
new cache.h in place (2014-7-26).
* arch/arm/src/armv7-a/cache.h: New cache.h file. Renames all functions
like cp15_XYZ_cache() to arch_XYZ_cache() and adds L2 cache support if
L2 cache is enabled (2014-7-26).
* arch/arm/src/sama5/*.c (many files): Change naming from cp_XYZ_cache()
to arch_XYP_cache() so that all cache operations will pick up L2
support if it is enabled (2014-7-26).
* arch/arm/src/sama5/sam_boot.c: Enables cache early in boot-up sequence
(2014-7-26).
* arch/arm/src/armv7-a/arm_l2cc_pl310.c and l2cc.h: Minor bugfixes/
improvements (2014-7-26)
* arch/arm/src/armv7-a/Kconfig: L2 Cache currently depends on
EXPERIMENTAL because it does not yet work properly (2014-7-26).
* include/nuttx/audio/audio.h: Move sub-sampling rate definitions from
* audio/pcm_decode.c: PCM: First cut at fast forward by sub-sampling.
This design is overkill: It manages too many audio buffers. I think
that a cleaner design could do all sub-sampling in place without
managing additional audio buffers (2014-7-27).
* drivers/audio/audio_null.c: Was not returning buffers to the upper
level (2014-7-27)
* include/nuttx/audio/audio.h and audio/pcm_decode.c: Misc bugfixes
while integrating fast forward by sub-sampling (2014-7-27).
* audio/pcm_decode.c: Back out a change; the fix really belongs in
NxPlayer. (2014-7-27).
* arch/arm/src/lpc17xx/lpc17_adc.c and arch/arm/src/lpc17xx/lpc17_ethernet.c:
ADC updates from Max. Also fixes some syntax errors that I introduced in
the last commit (2014-7-28).
* audio/pcm_decode.c: Fix a logic error in a DEBUG assertion (2014-7-28).
* configs/sama5d4-ek/src/sam_pmic.c, dram_main.c, sama5d4-ek.h, Makefile.
Add logic to disable the faulty PMIC. This must be done with JP23 open.
It is performed only from the DRAMBOOT loader (2014-7-28).
* drivers/audio/wm8904.c: Fix some compile problems with the WM8904 driver
due to recent audio subsystem changes (2014-7-28).
* arch/arm/src/sama5/sam_timerisr.c and configs/sama5d3*/include/board*.h:
Correct system timer frequency. Input clock is MCK/2, not MCK
(2014-7-29).
* fs/fs_automount.c and include/nuttx/fs/automount.h (plus hooks in other
files): Add support for an auto-mounter that will automatically mount
and unmount a file system a media is inserted and removed (2014-7-29 .
* configs/sama5d4-ek/src/sam_automount.c: Add automounter support for
HSMCI0 and HSMCI1 (2014-7-29).
* configs/sama5d4-ek/Kconfig and src/sam_hsmci.c: Minor warning/latent
bug clean-up of auto-mounter logic (2014-7-29).
* configs/sama5d4-ek/README.txt anand src/sam_nsh.c, fs/fs_automount.c,
and include/nuttx/fs/automount.h: Cosmetic updates to comments and
README files and some naming (2014-7-29).
* configs/sama5d4-ek/nsh/defconfig and nxwm/defconfig: The SAMA5D4-EK
NSH and NxWM configurations now have the auto-mounter configured to
automatically mount the FAT file system on HSMCI0 at /mnt/sdcard
(2014-7-29).
* arch/arm/src/sama5/sam_hsmci.c: Add method to do RX transfer without
DMA. The 8-byte SCR transfer was failing silently with the DMA
transfer, leaving the SD card in single bit mode (2014-7-29).
* arch/arm/src/sama5/sam_hsmci.c: Fix a problem on card insertion/removal
callback handling. Interrupts were being disable so that the callbacks
occurred with interrupts disabled. This resulted in loss of some
interrupts and some not-so-good behaviors. The solution is to perform
all callbacks on the work thread unconditionally (2014-7-30).
* nuttx/fs/fs_automount.c: Auto-mounter: Fix state setting. Not
harmful other than it can cause a debug assertion to fire if you
manually unmount the media before removing it which is, of course,
what you are supposed to do (2014-7-30).
* arch/arm/src/sama5/sam_hsmci.c and README files: Re-enable TX DMA and
verify that DMA writes to the SD card are functional. They are so now
TX DMA is re-enabled in the driver. This might affect the SAMA5D3
platforms where the TX DMA problem was found. The SAMA4D3 and 4 use
the same HSMCI driver. Much has change since then and it is not
surprising that DMA is now functional. However, the has not be re-
verified on the SAMA5D3 which has a different DMA controller
* arch/arm/src/sama5/sam_dmac.c, sam_pio.c, and sam_pioirq.c: Changes
needed for a clean SAMA5D3 build after all of the recent SAMA5D4
changes (2014-7-31).
* configs/sama5d3x-ek/nsh/defconfig: Refresh configuration (2014-7-31).
* configs/sama5d3x-ek/Kconfig, README.txt, src/sam_wm8904.c, Makefile,
sam_nsh.c, and sama5d3x-ek.h: Add support for the WM8904 audio CODEC
(2014-7-31).
* configs/sama5d3x-ek/nxplayer: Add a configuration to support the
command line NxPlayer (2014-7-31).
* audio/audio.c: More debug output (2014-7-31).
* configs/sama5d3x-ek/README.txt: REAME update (2014-7-31).
* drivers/audio/wm8904.c: Was not saving i2s interface instance
(2014-7-31).
* sched/sem_wait.c: Use set_errno() and get_errno(). Direct access
inside the OS may not be supported in the future (2014-7-31).
* drivers/audio/audio_null.c, vs1053.c, wm8904.c, include/nuttx/audio/audio.h,
libc/audio/lib_buffer.c: Change how the end of the audio stream is
detected by the leaf audio component. This used to be done by looking
for the first partial buffer. That does not work with the in-place
sub-sampling performed by the PCM decoder: That always reduces the
size of the buffer so that all buffers only partially filled by the
time they get to the leaf. Now, a flag is set in the audio buffer
flags set to indicate the final buffer in the stream (2014-7-31).
* arch/arm/src/sama5/sam_ssc.c: Needs to account for data offset in
audio buffer (2014-7-31).
* drivers/audio/wm8904.c: Can't reset the WM8904 unless we also
reinitialize all registers. Try to get a saner timeout based on
sample rate, bits-per-sample, and buffer size (2014-7-31).
* arch/arm/src/sama5/Kconfig and sam_ssc.c: SCC Frame Synch Delay and
Start Delay are now configurable (2014-8-1).
* drivers/audio/wm8904_debug.c: Add logic to dump WM8904 registers
(2014-8-1).
* drivers/audio/wm8904.c: Fix an error in write logic. I am not sure
why this fixes the problem (2014-8-1).
* include/nuttx/audio/wm8904.h (and implementers of the interface):
the WM8904 driver needs to know the frequency of the MCLK in order
to set up the FLL to generate the correct bitrate (2014-8-1).
* WM8904: Add an option to control WM8904 register dumping (2014-8-2).
* WM8904: Add logic to program the FLL to achieve the bitrate
(2014-8-1).
* arch/arm/src/sama5/sam_ssc.c: Verify that the requested bit width
is supported. Correct some alignment tests that depend upon the data
bit width (2014-8-2).
* audio/pcm_decode.c: Correct the end of audio stream handling. It was
not being detected before so that logic was not examining the WAV
header in the first buffer of the next audio file (2014-8-2).
* configs/sama5d3x-ek/nxplayer/defconfig: Update with last WM8904
settings (2014-8-2).
* drivers/audio/wm8904.c: Disable the FFL at the end of playing
(2014-8-2).
* include/nuttx/audio/wm8904.h: Fix wm8904_dump_registers macro:
Wrong number of parameters (2014-8-2).
* arch/arm/src/sama5/sam_pck.* and all SAMA5D board header files:
Add Main clock as an option for the PCK clock source (2014-8-3).
* configs/sama5d*-ek/Kconfig and src/sam_wm8904.c: Add option to
use MAINCK as source fort he WM8904 MCLK (2015-8-3).
* include/nuttx/audio/wm8904.h, configs/sama5d3x-ek/src/sam_wm8904.cm,
and sama5d4-ek/src/sam_wm8904.c: WM8904 interface enable method now
returns the previous interrupt state (2014-8-4).
* configs/sama5d3x-ek/src/sama5d3x-ek.h and sama5d4-ek/src/sama5d4-ek.h:
Correct the WM8904 interrupt configuration, active high level. Fix
that and don't pull-up (2014-8-4).
* configs/sama5d3x-ek/src/sam_wm8904.cm, and sama5d4-ek/src/sam_wm8904.c:
Correct ordering of some WM8904initialization: Need to provide MCLK
before initializing the WM8904, not after (2014-8-4).
* drivers/audio/wm8904.c and .h: Correct calculation of bitrate (I am
not sure why this is correct). LR clock divisor is now a constant 32-
bits per frame. Conditioned out interrupt logic; it is not being used.
Also added some FLL lock interrupt/poll logic (which was subsequently
disabled) (2014-8-4).
* SAMA5D3x-EK and SAMA4D4-EK: Add/update usage documents for media
players (2014-8-4).
* drivers/audio/wm8904.c and .h: Add reset logic to put the part back
in its initial state after playing each WAV file. Base samples per
second on frame length, not bits-per-sample. Use a different frame
length for 8-bit and 16-bit data (2014-8-4).
* arch/arm/src/sama5/sam_hsmci.c: TX DMA is again disabled for the
SAMA5D3 family. Although it works with the SAMA5D4 (which has a
different DMA subsystem), it does not work with the SAMA5D3 (2014-8-5,
see also 2014-7-30).
* audio/pcm_decode.c: Handle errors in the PCM WAV file in a way that
the Nxplayer can recover gracefully: Send and Audio Complete message
(2014-8-5).
* arch/*/src/*/*_timerisr.c, up_initialize.c, and up_internal.h: Re-name
up_timerinit() to up_timer_intialaize() for compatibility with new
tickless OS interface name (2014-8-6).
* arch/*/src/*/Make.def: Don't build existing timer initialization
logic if CONFIG_SCHED_TICKLESS is defined (2014-8-6).
* include/nuttx/arch.h: First cut at platform-specific interfaces
needed to support tickless OS option (2014-8-6).
* sched/Kconfig: Add a new option CONFIG_SCHED_TICKLESS to enable the
tickless OS. This is a work in progress but should be relatively
