ChibiOS Free Embedded RTOS

I'm not able to attach a debugger. The controller is programmed by SWD.

It is possible to debug through the microcontrollers SWD interface. I am using ST Link V2 and J-Link EDU debuggers. There are lots of explanations available on the internet for connecting a debugger JTAG interface to a board ...

do you have set CH_DBG_FILL_THREADS as TRUE in chconf.h?

Yes, it is set to TRUE and I also checked with the debugger that all the stack memory was set to 0x55.

I have thread where I statically declared working area with a size of 2048 bytes. THD_WORKING_AREA(waThread, 2048U); When I debug and look in ChibiOS/RT 3.x.x Debug View -> Threads tab then the StkUnused is ...

There are some errors in the comments to function chsnprintf. For example the comments say it is a vprintf implementation.

I am using the UART driver setup with USART1, TX requests on DMA1 channel 4 and RX requests on DMA1 channel 5. When I am using uartStartSend then only half of the bytes are send.

The problem is that with ...

You forgot a part of the change. Selecting MCU type STM32F030xC will fail because STM32_HAS_TIM7 is then redefined.

It seems like an if check implemented in function _pal_lld_setgroupmode for STM32/LLD/GPIO version 2 and version 3 is incorrect. The if check can only become true when the input ioportmask_t mask equals 0x01.

Hi Giovanni,

Thanks for the answer. I am more and more impressed by ChibiOS and the thoughts behind the different implementations.

chDbgAssert is the ChibiOS implementation alternative to using assert but the implementation still have one of the same problems.

I got this recommendation from a embedded newsletter:
The assert macro disappears when the debug switch isn't defined. But assert can take any argument, including ...
