I've just downloaded the Debian-server mainline image for my Olinuxino A20 Micro (Armbian_5.38 etc) and tried, without success, to change the video output from the default HDMI to the VGA one.

Following the documentation (https://docs.armbian.com/Hardware_Allwinner/) I modified the boot.cmd file adding the lines:

setenv video-mode sunxi:monitor=vga,hpd=0,edid=0
saveenv
and recompiling it but the video continues to be enabled on the HDMI output, also after 2 (and more) restart.

I noticed that in the boot splash screen a "Err: VGA" is reported.

It's not too clear from the documentation if this setting can be applied also modifying the armbianEnv.txt file or if editing and recompiling the boot.cmd file is the right way, anyway my question is: what should in order to enable the VGA output?

Thank you in advance

I have the same problem on my Cubietruck.

On legacy kernel i was able to use script.fex file on /boot directory, but this method has changed on mainline kernel. I don't know how to figure it out!

I've used this  workaround and it works!
