Hi @Ara.1​ 

Please share version and configuration you are using ( machine, image .. )

Is it default distribution package or with files edited by yourself ?

Thx

Olivier

Looking at the error message, it seems there is a device tree whose name does not begin with "stm32", and the "u-boot-stm32mp-extlinux-2.0-r0" does not support that case. I would check if all device tree names begins with "stm32".

Yes my customized dts doesn't not begin with stm32
