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

Nucleo board can't program or debug after upgrade.

I tried various versions. As a result, OpenOCD Ver. 2.4 works without problems. But Ver 2.5 and newer ones do not work with the same error message.
Is there any difference between Ver2.4 and Ver2.5? What is the cause?
