Hi, same problem, after armbian-add-overlay vga.dts nothing works: no VGA, no HDMI.
Does latest armbian supports cubietrack vga mode?
Also I've tried this thing(during boot I press space and the enter commands):
setenv video-mode sunxi:1360x768-24@60,monitor=vga,edid=1
saveenv
reset
saveenv says: Failed to save.
Is this still true?
