Alwinner A20 Micro won't output HDMI



Hello there,


I just flashed latest armbian (downloaded yesterday) on my A20 Olinuxino Micro. Version was with legacy kernel as my use case involves multimedia. SD card is Samsung Evo 128GB.

Once I attach HDMI display, I can see armbian logo and something happening (booting kernel etc) just for a few seconds, then screen flashes with colors and I don't get anymore signal. I tried with two monitors with the same reult. Later today I will try using cable-f attached to pins to see wether something is happening under the hood (I expect yes). In the meantime can someone confirm this issue? What should I try in order to fix this?


Thanks in advance for any help on this.

Ended up issue was already described here 



Solution for me was to bin2fex micro.bin file and replace


screen0_output_type = 1
screen0_output_mode = 5
screen1_output_type = 1
screen1_output_mode = 5



screen0_output_type = 3
screen0_output_mode = 4
screen1_output_type = 0
screen1_output_mode = 4

taken from lime.fex here https://github.com/armbian/build/blob/master/config/fex/lime2.fex



You should consider fixing this upstream, as current a20 olimex micro legacy image won't output on HDMI out of the box
