Support for Olimex's LCD panel does not appear to be working in the latest builds (stable kernel 5.8.6, development kernel 5.9.7)
My understanding is that this has been an issue for a while with A64 boards, specifically the Pine64, but that it was working at one time.
Here's what I've tried so far:
-Followed instructions at https://docs.armbian.com/Hardware_Allwinner/ and added "setenv video-mode sunxi:480x272-24@60,monitor=lcd,hpd=1,edid=1" to boot.cmd and put "saveenv" at the end, re-compiled boot.scr
-Did a modprobe of panel-olimex-lcd-olinuxino
-Rebooted several times
-Ensured that LCD jumper was closed and verified LCD was working with Olimex builds.
Screen flickers at startup then stays white.
I did notice that according to the hardware notes in armbian docs that CONFIG_VIDEO_LCD_MODE must be enabled in U-boot configuration and is not.
It seems a solution would involve being able to custom build u-boot using the steps mentioned here: https://forum.armbian.com/topic/16054-olimex-lcd-panel-support-for-a64/?tab=comments#comment-113408
and somehow getting Armbian to use the custom-built u-boot.
