Hi @Ara.1​ ,

Looks like you are using a custom environment ( warrior + basic boot chain from V1.2 ecosystem) on a custom design based on SOM.

I'm afraid this is too much custom to be efficiently supported in this community.

I you confirm you are using a part from SOM maker integrating STM32MP1, please be aware that the SOM maker supposed to be your favorite support contact.

If not please give more details in order we can provide relevant support.
