From looking at your logs, looks like a Device TRee issue - failed to identify key hardware parameters by the looks of it for some reason - change in boot settings? regards Andrew

Can i get some help,I have Uart adapter and can provide logs

TI SK-AM62A7 is not supported by Armbian, can I use Armbian and create a custom debian based image for TI SK-AM62A7. Support for TI SK-AM62 is there. Kindly guide me on how can I start building my custom image for TI-SK AM62A7.

That should be O.K. too.
