Android kernel not booting on iMX8MP platform, instead it shuts down.

swapnilpendhare — Mon, 09 May 2022 21:37:44 GMT

I am trying to port Android 11.0.2.6.0 on imx8MP based EVK board developed by Compulab.
the board name is ucm-imx8m-plus evk board.

When i am trying to boot kernel i am getting following mesg and kernel reboots. What could be the problem.
