Hi, I’ve managed to get the kumantech 3.5 inch screen kinda working. But unfortunately it stops working a few seconds after booting. It hangs and doesn’t update the screen anymore.

I’m testing it with a waveshare 3.2 inch display right now and this display hangs after a while, too. But this time it took several minutes before it stopped working.

Do you have any idea what’s going wrong here?

I’m on the latest Armbian Ubuntu xenial image.
