I would change the way to get to the U-boot prompt.

When waiting for x seconds autoexcecution.
Change “Any keypress” by a fixed key.

Example: To enter the U boot prompt press the key “s”

I can not find the function in DIGI EL to recompile U-boat

thank you for your help

You should look into

{WORKSPACE}/{project_name}/build/U-Boot/common/main.c

satic inline int abortboot(int bootdelay);
