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:

Seen this a few times on various STM32 processors (currently working on STM32L073). I’ve found that its a problem with the NRST line on the STLINK. Don’t know why, the NRST is working and is not being held by anything. Go into the debugger setup and switch to “Software system reset”, then it works.
