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 (registration required) various documents highlighting:

FreeRTOS Thread Debugging with SW4STM32



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...
