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:

I use “File->Export->General->File System” and export the entire project tree. If I need go read it back in I use “File->Import->Existing Projects Into Workspace”.

The example projects are in the repository filesystem tree, and have relative paths referencing other objects in that tree. That may be the cause of your error. I leave the examples unmodified any copy any bits I want to a project that was created in my workspace.
