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 CRC check

Thanks looks good. I guess you add the srec_cat to the build steps? What is your command there? Does the srec_cat glues the crc to the end of the file?
It can be handy to place a const struct on a fixed position in the flash, any idea how to do that?
