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:

Thank you for your patience.

In annex I put the *.map file.
this map file is obtained after you have fixed the project

Now I’ve changed the linker to “STM32F746ZGTx_FLASH.ld” and works fine!
Glad to hear that

But I do not understand why this change... why, in a momment works nice, and the next momment all of this goes crazy...
You probably have intentionally discarded the linker settings so the arm_none_eabi_ld have used the default setting (flash at address 0)
