I would like to sign my binaries before flashing them. The purpose is to check integrity before my bootloader jump into.
So i would like to call a script which adds a hash in a specific structure in my binary and i would like to call this script before flashing. But the target “make flash” depends on “all” and recompile all my files before the flash, so it will erase my hash.
Is there a way to do this without modifying the RIOT makefile. I saw that there is a “preflash” target that isnt used.
If you have any idea, feel free to share
