uConole black screen, hdmi output

uConsole

Hello,

I’ve just received my CM4 uConsole and am running into a problem with getting the screen to power on. When I power the machine on, the screen blinks once and then no matter how long i leave it sit, there is no video output on it. If I plug the mini hdmi into another screen, however, I get console output, so I know that the CM4 is installed properly. I’ve reassembled the device twice now, and reseated the ribbon cable for the screen at least 5 or 6 times now. Has anyone experienced similar and found a fix?

I would probably re-image the card from their github image… sounds like the kernel patch isnt fully there

That did it! I get video on the device now. Thank you so much, I think I can take it from here.
