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 (registration required) various documents highlighting:

System Workbench for STM32


OpenOCD not working under System Workbench

Yes, the stlink configs are kept but not used really (default is stlink v2.1 i think but it is not really important, openocd scans all the stlink board version and adapts itself to the stlink found).

So, maybe you have a custom board and you don’t connect the reset line from STlink ?
If it is the case, you should change the reset option in SW4STM32 (Software system reset), it is “Connect under reset” by default.

Or as i said, you had an appli already connected to the stlink ?
