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

Re: SW4STM32 or CubeMX to init STM32 device


Currently CubMX is not yet fully integrated with System Workbench for STM32; in a future version of CubeMX it will be possible to generate directly System Workbench projects.

In the meantime you can just copy a few files from th eCubeMX generated files to your System Workbench “src” folder:
main.c - the main program generated by CubeMX (includes most initializations)
stm32fyxx_hal_msp.c - low-level core initialization (mainly interrupt-related)
stm32fyxx_it.c - HAL interrupt handlers (mainly the SysTick interrupt)

This should be enough to initialize your board correctly.
