NOT Getting an HDMI output on IMX8MQEVK

[Priyanshu1069]

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

HI Joanxie,

I have attached the log file herewith.

I am using fsl-imx8mq-evk-dcss-adv7535.dtb file.

Thanks,

Priyanshu.

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

[Priyanshu1069]

Yes. I have tried using "saveenv" commad, still no output.

[joanxie]

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

Hi joanxie,

I am using imx8mq board version A1.

Thanks,

Priyanshu.

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"

pls share your log file with me, what dtb file do you use?
