i.MX6UL nand configuration in 4.19.35 kernel

[ganesh_k]

Hello everyone,

Greetings of the day...

kernel verison: 4.19.35

issue: unable to load the rootfs image, getting kernel panic.

I am working on imx6UL, i m trying to boot from nand. but while booting, at the stage of the rootfs(ubifs) image getting below error. What might be the issue here. Please suggest.

Hi Ganesh

one can try to follow guidelines provided on :

How-To use NAND boot on i.MX6UL EVK board 

Note, use exactly uboot imx_v2019.04 (not v.2017.04)

uboot-imx - i.MX U-Boot 

linux-imx - i.MX Linux kernel
