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

Programming Application in Specified address and Debug



Your problem was described, and solved, in several forum topics; for example look at http://www.openstm32.org/forumthread2364Question, the previous to last post explain how to avoid the bootloader to be erased when programming the application and may help you.

Also do not forget to change the vector table offset as explained in the same post.

For more information on this just do a search for “bootloader” in the forum.
