NOT Getting an HDMI output on IMX8MQEVK

Hi,
I just started exploring with i.MX8MQEVK.
I flshed the pre-build image “LF_v5.10_2.0.0_images_IMX8MQEVK.zip” which is available at NXP site.


Then i connect IMX-MIPI-HDMI exactly in the same way as mentioned in the document link  “Quick Start Guide for IMX-MIPI-HDMI for i.MX 8M Evaluation Kit” and followed the same step.


I also connected a screen through HDMI (one end at the MIPI-HDMI and the other end at the monitor screen) and expected to see the image on HDMI monitor after boot completes.

Also, while booting the board i am getting the below lines

[FAILED] Failed to start Terminate Psplash Boot Screen.
See 'systemctl status psplash-quit.service' for details.

Not sure if this is causing the problem.

Can you please help me in this?

Thanks,

Priyanshu

after set the fdt_file, pls don't forget to use "saveenv" command to save the settings

what imx8mq board version do you use? A1 or B3? pls check the back of your board, then I can reproduce this on my board

I found the reason, you should change the fdt_file to imx8mq-evk-dcss-adv7535.dtb right, in the latest bsp, use fdtfile to replace fdt_file, so try to "setenv fdtfile imx8mq-evk-dcss-adv7535.dtb" then "saveenv"
