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.

Bootloader CRC check

I’d recommend using the open-source utility “srec_cat” to embed a CRC into your object file. It’s also capable of doing a lot of other things related to manipulating object code files.


I recently wrote a bootloader for a project I worked on recently, and I had do come up with a way to do exactly what you describe - insert a CRC of the image into a fixed location within the object code file. I used srec_cat to accomplish this.

You will want to run the srec_cat utility as part of your post-build process. I’d suggest making a small shell script (batch file) that runs the srec_cat program, and run the script/batch containing all the utilities you want to run (including srec_cat) as your post-build step.

Learning how to use the SRecord utilities can be a bit dauting. They can do a lot of nice things related to manipulating object code files, but this flexibility comes at the expense of ease of use. Fortunately, the author does provide comprehensive documentation.

I can provide some assistance in using srec_cat and setting up a post-build script to do this if you need it.
