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:

Hello Sylvain,

Afer investigation, we confirm there is a bug in Openocd L4 flash driver. I can’t tell when it will be fixed as it is not an obvious issue.

But we have found an easy workaround : before launching the debugger, you shoud erase the memory : select the project in the Project Explorer, right click, select “Target” and then “Erase Chip”.

Let us know if this works,

Best Regards,
