when board boots, display switch from white to black. Without console output.

 

gpio readall - looks good. all pins present.

 

when I try Armbian_25.8.1_Orangepione_noble_current_6.12.43.img.xz

board boots. add overlay to it, by armbian-add-overlays

remove HDMI cable. (Really good first-config over ssh, why not to add this to other boards, like mine?)

reboot

Display works(Ony if HDMI is unpluged), with output of boot Armbian.

 

I`ll think this something wrong with output on spi LCD over OrangePi PC Armbian build, or sometning like that way....

Any advise?
