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

not possible to debug - configuration of GDB fails

Be careful, the stlink-v2.cfg is not wrong :

VID/PID 0x0483 0x3748 for ST-Link/V2
VID/PID 0x0483 0x374b for ST-Link/V2-1

There is a stlink-v2-1.cfg if needed.
