Hello. I was playing around with Debian on the STM32mp157F-DK2 and stumble on this issue/bug when I tried to debug M4 from CubeIDE and got something like this:

It happens that autogenerated fw_cortex_m4.sh script file has some syntax issue which prevent the firmware loading on Debian (shellcheck.net does complain):
#if [ $1 == "start" ] # Need to be replaced with the next line
if [ "$1" = "start" ]
#if [ $1 == "stop" ] # Need to be replaced with the next line
if [ "$1" = "stop" ]
This issue was discovered a while ago here at DigiKey forum but I guess was never addressed in CubeMX
