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:

Bootloader and Application Code

Hi Luca,

Did you try to do instruction-level single-step execution over the last lines of jump_to ? You should especially check that the value in SysMemBootJump is odd (as this is Thumb code, this should be OK) and that you are currently using the MSP stack pointer (check the CONTROL register: it must be 0).

Also at which exact instruction does it crash? and does it just jump in some infinite empty loop (meaning you hit some exception) or does is locks up?

Currently I don’t have any way to test your code but it looks reasonable.

Hope this helps,

Bernard (Ac6)
