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:

thanks for yhe feedback. Now that you mention “virtual com’ it triggers some old memory.

I al;tready tried switching from Uart2 to Uart1 (pa9,pa10) but for some reason I don’t get any data ouyt of that either. migh be my mistake with the setup though. Still requires some more exploring.
