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:

System Workbench for STM32

Debugging setup issue on ST discovery and eval board


These are known problems with CubeMX (you didn’t mention the projects were created by CubeMX).
We hope ST will have corrected CubeMX SW4STM32 project generation in a forthcoming release of CubeMX (and then update the example projects delivered with their firmwares).
Thanks for your patience,
