Hello,
As far as I know,
STM32 does not support the POSIX abstraction layer for FreeRTOS.

That means I can not use functions like:

  • Interact with tasks through: 'pthread_create', 'pthread_join'..
  • Use POSIX glue elements like: 'pthread_mutex'...
  • Etc

If I am porting a big FreeRTOS project that is using POSIX to STM32:  what I need to do? Is there a way of achieving it painlessly?

Thanks,

Carles

Anyhow, there does seem to be such support in ThreadX - which is becoming ST's favoured RTOS (replacing FreeRTOS).
