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:

How to make a Release configuration?


>> AC6 should write in Flash by default, shouldn’t it?
Yes, it is the case

>> I will check tomorrow signal NRST on scope. As far as I remember I did it. I can capture reset process.
>> What do you want to seen in it?
Just to verify if the mcu is held under reset or not

any way, you can launch your application in standalone mode, then try to connect to your mcu without reset (hotplug mode) using st-link utility, then read your program counter register (menu > target > mcu core). That will give an idea of what is going.
