SW4STM32 and SW4Linux fully supports the STM32MP1 asymmetric multicore Cortex/A7+M4 MPUs

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world.
And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4.
You can get more information from the ac6-tools website and download two short videos (registration required) highlighting:

System Workbench for STM32

FreeRTOS Thread Debugging with SW4STM32

interstesting i’m not yet at this level (CubeMx proj on Discoveryf4)
i added the freetros in cfg file
i added the helper symbol

start debug gdb start but not wokring
in debug view no stop pause no thread frown

what appar on the end of the gdb console

New Thread 1
Warning: the current language does not match this frame.

New Remote target
Switching to Remote target
Invalid selected thread.

it work witthout the rtos configure in cfg but no Rtos awarness



The problmem may be that OpenOCD sees there is FreeRTOS in your applications, but it can’t get the list of threads as there is no initialized data and no thread list; if you put a breakpoint after creating the first task (or better in the body of the first task) instead of putting it at main it should work.

We are looking at a solution for this but, regretfully, it will take some time...
