BIGTREETECH CB2

Hi, ive been trying to resolve the screen issue issue on my cb2 for a few days now, i cannot get it to work. I'm running Armbian_26.2.1_Bigtreetech-cb2_trixie_current_6.18.8_minimal, everything works. HDMI outputs to a 4K display just fine except for my small 5" display, which just stays black. The os has not been tempered with, i've flashed a fresh copy and used armbian-upgrade it, thats all. I've diagnosed the problem enough to see that its an EDID issue or the rk3566 just not likely my weird screen resolution. BTT os who also use armbian as a base somehow fixed this official issue. The display is being detected by the OS. My Armbian OS: root@big…

I'm using Armbian with kernel 6.12 on a (CB2) device. When I connect my monitor via HDMI, the EDID is successfully read and it includes both 1920x1080 and 1280x800 as supported resolutions. However, only 1920x1080 appears in the available display modes. The 1280x800 mode is missing, even though it is clearly listed in the EDID.

I have an extra CB2 laying around and want to set it up with Home Assistant. However, I think I have tried all the google search and am not able to find the answer. Thus I am wondering if CB2 would be supported by Armbian community? I am currently on BTT V3.0.0 Beta 2, and got crashed (no boot) after I tried to install the docker, so I guess the BTT CB2 V3.0.0 does not fully supoort other program except Mainsail for 3D printing.
