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

Create script failure: fail to retrieve target

I reached the same conclusion and used the same workaround... Except that I retrieved a cfg file from trash.
This bug appeared here last Friday (MAR/8th), out of the blue. Tried to reinstall everything from scratch 3 times, did not have time to downgrade versions to discover wich restablishes .cfg generation functionality... You guys owe me a weekend ;)
