hi.. @Daniel

Many Thanks for the support

This resolve the issue

EXTRA_USERS_PARAMS += " useradd -m -s /bin/bash -P 'mahi' root;"

however,  when i build the image and try to login with the board then I can't

it's always returning as an incorrect password!

here is the logs .....

stm32mp1 login: root
Password: 
Login incorrect

What's wrong with it ?

Thanks
