ChibiOS Free Embedded RTOS

Hi,

Could you post your halconf.h, mcuconf.h files causing compilation errors?

Giovanni

Certainly.

For reference, the RT-STM32G0B1RE-NUCLEO64 demo exhibits this behavior.

With a fresh copy and the only change being the ChibiOS directory path it compiles fine.

If you make the further changes:
#define HAL_USE_PWM TRUE
and
#define STM32_GPT_USE_TIM3 TRUE
#define STM32_GPT_USE_TIM4 TRUE
then it fails with

I have also attached the project. Thanks.

Hi,

Fixed in repository trunk.

Giovanni

Thank you. I have verified that the TIM3, TIM4 PWM channels are working as expected on my board.

I cannot reproduce the PF3-4 PAL_MODE_INPUT_PULLUP causing crash bug in an isolated example based on the example in the trunk, so it was probably a mess up on my side (apologies). I will keep digging.

Thanks again. This really helps.
