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.

Hey richard,

This seems very interesting, but your code deos not get through correctly.

To provide code you should bracket it between CODE tags:
    place your code here
    #include < header.h >
    #include "header.h"

Moreover, regretfully, code that look like HTML tags (that is between angle brackets < and >) is suppressed even in CODE blocks, except if there is a space after the opening bracket (like above) so either slightly edit your code by adding a space there or change the includes to use quotes instead... I was able to correct the rest of your post, but I don’t get the name of the files to include...

Could you edit your post to add the rpoper header files?

Thanks for sharing your results
