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

Hack to remedy crashing issue on Mac

The basic reality, now, is that this issue is out of date because STM32CubeIDE now supports Mac/Lin/Win. It’s Atollic for STM32, it’s free, it’s excellent, and if you’re using OpenSTM32 SystemWorkbench instead of STM32CubeIDE, I assume it’s only because you don’t know about STM32CubeIDE.

Certainly there’s value in having an Open Source IDE option, but if I were the OpenSTM32 devs, I’d change my release strategy.

In any case, ((https://www.st.com/en/development-tools/stm32cubeide.html|STM32CubeIDE))
