You get this when the pi cannot communicate with the epaper. Which version of the centaur board do you have? 1 or 2. Also which version of DGTCentaurMods are you...

Okay, that makes sense already. Debian doesn't have the right drivers in it. We haven't yet found a way for it not to be Raspbian 32 bit. What was wrong...

With raspbian 32 bit? Did you have wifi?

Did you apt upgrade and apt update?

Perhaps could try: sudo systemctl disable hciuart.service sudo systemctl enable bluetooth.service possibly check it isn't disabled in /boot/config.txt . For the error - the waveshare file used falls back to...

It uses the existence of /sys/bus/platform/drivers/gpiomem-bcm2835 to determine if it's a raspberry pi or not. You won't get the same error message on 1.3.2 though as it's a different driver....

That driver is apparently only in Raspbian OS.

This is odd, ct800 and maia games just worked for me. Does this problem still persist?
