Hi,

I the MIPI-HDMI output works fine during uboot. Once it starts loading kernel, the display vanishes. 

I am attaching the uboot setting. Please let me know hat's wrong with the settings.

Hi,

   It is imx8mm evk board. It was based on build 4.14.78. The person who built the package doesn't work with us. I loaded pre-built image of latest version 5.15.5 (imx-image-full-imx8mmevk.wic). The display MIPI-DSI to HDMI works fine. I have attached the uboot and kernel messages in my previous post. Is it possible to figure out from that what is happening ?
