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:

Looking for a dev board for System Workbench

Can anyone recommend a dev board for System Workbench for STM32?

I’ve just downloaded/installed System Workbench for STM32. My purpose is to learn the ST environment; I don’t have a particular project to implement at this time.

I looked up Digikey but could not be sure that any of the dev boards were compatible with the System Workbench environment, debugging interface etc.
