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:

SW Crashes after hitting Run or Debug

I’m having the same problem on mac now and there is no clean solution, the latest suggested solution messes up the arm compiler paths. The latest independent installer is for 2017 which is very very outdated. The page that explains installing from eclipse claims it is compatible with 2019-12 version but cannot handle the PATH and doesn’t find the arm suite.
