Hi, I'm new to yocto project, I'm trying to set password for  custom image in yocto in stm32mp157d-dk1(scarthgap) ,by editing the bb layer in image, its successfully build and flashed into SD card , but I'm trying to enter the login id and password , it says login Incorrect  ,I tried in all ways , but still it shows login incorrect ,

I attached the Picture of the bb layer of my image above , Please anyone could tell me  what I'm missing there..

Hello @Anto_Z ,
Are you sure the password is not blank here ? 

In you conf/local.conf file in <Yocto build folder>, we have a default setting that is :

EXTRA_IMAGE_FEATURES ?= "debug-tweaks"

This feature is supposed to remove password for root user. Maybe you can try to remove this feature and make another try.

Kind regards,
Erwan.

Hi @Anto_Z 

please have a look to this post https://community.st.com/t5/stm32-mpus-embedded-software-and/the-root-password-how-to-set-during-compilation-the-openstlinux/m-p/618515

Note: the password is not stored in plaintext, you should generate the correct hash string using e.g.:

openssl passwd -5 xxxx  

Then as stated in the linked post, manually escape all $ with \ before copying in the usermod line

This link (in french) could help too: https://www.blaess.fr/christophe/yocto-lab/sequence-II-1/index.html#utilisateurs-et-mots-de-passe

Hi, Thanks for the help, i commented that line, and tried , then , I can't able to login as root , bcoz , commenting that line also remove the  root login, then i added the below line

EXTRA_IMAGE_FEATURES += "allow-root-login"

 and , i used encrypted password assignment instead of direct assignment ,  then, its worked fine
