I have both HDMI and DSI connected, neither work. DSI shows just black screen. HDMI shows desktop background like extended monitor. This is with a 3b+, does this only work with a 4?

OK. so now bookworm loads and I have the board connected. When the Duet2 board runs 3.4.6 it gives an error that the versions are incompatible. When I update the board with Bossa to 3.5r3, it says it can't find the host. What can I do to get you access to take a look....
