Which version of BSP are you using? Are you using the demo images or images you build yourself?

Hi Rita,

First I have flashed the (LF_v5.4.y-1.0.0) demo image in i.MX8M Quad Evk and board boot up successfully.

After that i have create custom layer in yocto and build the custom images.

I have flashed the custom images but system doesn't boot-up. After that I have flashed demo images but board not boot-up.

For the demo images can work, we have tested on our board. You make sure the boot mode and boot command are right. You can retry it.
