POSIX support in STM32

selracelosuarg · ‎2025-02-21

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

Hello,

I don't think POSIX-FreeRTOS is supported natively by STM32 but I think you need to do it yourself. See https://www.freertos.org/Documentation/03-Libraries/05-FreeRTOS-labs/03-FreeRTOS-plus-POSIX/00-FreeRTOS-Plus-POSIX
