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:

Hi Again,

The “Additional drivers” are not drivers to install on your Linux but are the code generated in your project for the board to control USB devices. Anyway, this option is not what causing your problem.

Can you open a terminal then run “killall openocd” to kill every running OpenOCD connected to the ST-Link. Maybe one application is blocking access to the ST-Link.

By the way, do you have the same issue when running a debug session ?
