I need some help on how to set up and use the "su" command within yocto jethro.
I have added two users into yocto, one is 'root' while the other is 'normal'. They both have its own password and I can ssh into either user from a different machine.
but when I issue command "su" and want to switch from user 'normal' to 'root', even with a correct 'root' password, I am still getting "su: Authentication failure" and not able to switch to root.
If you can help me with this would be much appreciated.
