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

not possible to debug - configuration of GDB fails

Hi Dominik,

I’ve just tried to bridge the ST-Link/V2 from an F0Discovery on the VLDiscovery as you suggested. You only need is to modify the OpenOCD configuration script (to use the ST-Link/V2 instead of the ST-Link/V1) and it will work.

You can find my OpenOCD script in attachement.

Best regards.
