557fd6504f pthreads: Move pthread_once from sched/pthreads to libc/pthreads. pthread_once just coordinates other OS interface calls but is not a fundamental OS interface and, hence, does not belong within the OS. 2017-06-14 07:31:10 -06:00

testbuild:Added -x to fail build on errors for CI

48fb789cf3 testbuild:Added -x to fail build on errors for CI 
On CI we want to know ASAP of a failure. This adds the
   -x (exit on build failures) option to faclitate that
   behavior.

   Use ${MAKE} ${MAKE_FLAGS} for make invocation.
   When -x is provided change MAKE_FLAGS to
   --silent --no-print-directory and set -e

   Ignore exit status when using grep for checking
   for CONFIG_NXWM=y

7b8df1b930 mtd/w25: wait for BUSY flag to clear in w25_readid and w25_unprotect. W25Q128 datasheet says that all instructions expect 'Read Status Register' and 'Erase/Program Suspend' are ignored when BUSY flag in status register is '1'. Therefore wait for busy flag to clear in w25_readid() and w25_unprotect(). 2017-06-13 07:35:49 -06:00

e379491d13 STM32/STM32L4: Review of last commit -- Eliminate possible underflow 2017-06-13 07:05:46 -06:00

7903a8a46c stm32/stm32l4 PWM: While attempting to output a 70 MHz square wave from the timer output of a STM32 clocked at 140 MHz (which works fine in baremetal C), I stumbled on what I believe to be an error in arch/arm/src/stm32/stm32_pwm.c. Line 1304 we are told that 
reload = timclk / info->frequency;

which I belive to be incorrect, it should be

reload = timclk / info->frequency - 1;

since starting to count from 0, if I want to output half of the TIM clock, I must count to 1 and not to 2.

Surely enough, the original code did output 140/3=47 MHz, while this correction does allow the output up to 70 MHz.

I am not sure this affects most users generating slow PWM (e.g. PX4) but for frequencies
close to the PCLK, indeed the difference becomes significant.

0a85a41678 MTD FLASH driver: Clone Sebastien Lorquet's m25px change to at25, is25xp, ramtron, and sst25xx. 2017-06-12 09:51:42 -06:00
Sebastien Lorquet
2851959dee MTD M2PX: If we READ while a write/erase is pending, the command is ignored and the write/erase continues. If we dont catch this situation we will return garbage to the user because the flash will not execute the command. So READ MUST wait for write completion, and before that, the bus must be locked since it's a precondition to calling waitwritecomplete(). 2017-06-12 09:34:09 -06:00

  Output pin:    Value=1
  Writing:       Value=0
  Verify:        Value=1

Now:

  Writing:       Value=0

4504ca7c82 Whoops -- that #include <cxxabi.h> wasn't supposed to sneak in there. If present, it may already define a __cxxabiv1::__guard that we could use, but that file comes from libstdc++, and I don't think the NuttX buildroot-based toolchain would have that, which is why we need libxx in the first place. 2017-06-09 07:40:31 -06:00

18289e17ce Fix C++ __guard implementation for ARM. The standard C++ ABI that most platforms follow defines __guard to be 64 bits. The existing implementation of libxx_cxa_guard.cxx follows this. However, the 32-bit ARM C++ ABI defines it as 32 bits instead, and changes the meaning slightly so only the lowest bit is used. This matters because GCC creates guard symbols without regards to what libxx_cxa_guard.cxx says. So on ARM, gcc allocates 4 bytes, but __cxa_guard_release writes 8 bytes, zeroing out another unlucky variable nearby. Fix it by special-casing 32-bit ARM in libxx_cxa_guard. 2017-06-09 07:16:00 -06:00
