AM625: My AM625 custom Board , HDMI display with slightly blue line and boundary

any one can help ?

Jack Wang

Hi Jack,

Is that a custom board or TI SK EVM? Also, is that a standard 1080p monitor? Lastly, is the issue reproducible upon every boot or it's intermittent?

Dear Krunal ,

We use our custom board and the monitor is Asus VA249HE standard 1080P . This  issue is  reproducible upon every boot still and every boards .

Do I need to give you the related schematic ?

Hi Jack,

If you disable weston and run kmstest, do you see the same lines appearing on the monitor? Also, are the blue lines always appearing on the same side of the monitor?

Dear Krunal ,

Run Kmstest shown as the attached picture , it seems no the same line appeared , also no blue lines on the same side .

Hi Jack,

I would recommend you to try running other examples like: kmscube -D /dev/dri/card0, glmark2-wayland and various Qt tests under /usr/share/example/qt5. I am wondering if the blue lines is only associated with that particular demo.
