Kernel getting stuck

[sd05]

Hello Community,

We are using the Zeus Yocto version and we switched the uboot version from 2019 to 2020 and after that Kernel getting stuck with the following errors.

What can we do to resolve this issue?

Thanks in advance!

Hi Sunidhi

from log : "Linux version 5.4.3-imx8mm", linux 5.4.3 was used while for uboot version 2020

linux 5.4.24 version or newer is required, so may be suggested to upgrade linux:

https://github.com/varigit/linux-imx/tree/imx_5.4.24_2.1.0_var01

Best regards
igor
