Issue with IMX8MM’s GPU

[omidid]

Hello,

I build uboot and kernel and all other required things such as NXP firmware for imx8mm and also I used downstream as it is mentioned in documents.

I use DSI to HTMI driver and LCD blinking to white and black randomly and I do not see anything in output. As you can see in the log below there is some errors in loading DRM driver.

In additional I build imx firmware with gpu-viv for imx8mm too.

After boot I can see /dev/dri/card0 but it is not possible to use it. DRM will crash and lcd blink again. It look like it is trying to load driver again and timeout for another 30-60 seconds.
