STM32MP1 support available in SW4STM32

   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 download a short video showcasing this on the ac6-tools website (registration required).

System Workbench for STM32

Nucleo board can't program or debug after upgrade.

I was also annoyed with the same symptoms. I solved the problem as follows.
・ Uninstall SW4STM32 Ver. 2.8
・ Install SW4STM32 Ver2.0
Maybe OpenOCD will work even if it is newer than Ver2.0.
I will continue to try out which version it can work with.
