[Cubietruck Armbian Bionic Desktop black screen]

Well, I have bad news.

After 17 months, I had to reinstall because of sdcard corruption .

I reflashed Armbian_5.90_Cubietruck_Debian_buster_next_4.19.57

So, installed version of linux-u-boot-cubietruck-next still doesnt work with VGA and version 5.35 is not in repositories anymore.

I dont know what to do either. I'll keep using my cubie as a headless server but Its a shame, VGA output was an important factor why I bought cubietruck in the first place.

Now my old VGA monitor became pretty useless.

Perhaps peeking into the documentation first would save some time

Well, yes ... I found this after I've tried a few things on my own.

"You can do this by adding saveenv command at the end of boot script (boot.cmd)".  I did this! I wrote "saveenv" as a last line of boot.cmd, didnt work.

I tried different resolutions with edid=0 and 1 for each. I've compiled boot.cmd and rebooted twice for each to be sure... Nope.

Somewhere in progress I've noticed I do make a (common, I  guess) mistake by using "="  instead of <space> between videomode and sunxi:...

Repeated above all over again :/

Nothing.

Even I've tried replacing u-boot with some custom builds from random bloggers. None of them worked of course.

 

Then I had to  read several pages about what is u-boot and how it works and I discovered u-boot console, finally.

( after a few dozens of trials and errors)  replying my own question for future reference :

All changes at armbianEnv.txt and boot.cmd  was not enough. I needed to enter u-boot console at startup and write those:

 

setenv video-mode sunxi:1360x768-24@60,monitor=vga,edid=1

saveenv

reset

 

then it worked.

I've noticed this thread after that

 

I've tried downgrading u-boot as written here but unfortunately my cubietruck still outputs to HDMI no matter whatever I tried :/

What else I need to do ? Could you give me a correct configuration for this please?

[Cubietruck mainline kernel vga out]

Hi, my old 1366x768 VGA LCD monitor was working with legacy kernel but after I downloaded and installed image with new kernel ( Ubuntu_xenial_next.7z)  I could not get it to work with VGA output.

When I set armbianEnv.txt with below, it still outputs to HDMI

disp_mode=1366x768p60
video_mode=sunxi:1366x768-24@60,monitor=vga,hdp=0,edid=1

 

then I tried to add this with no luck. Both monitors go blank with it.

extraagrs=disp.screen0_output_type=4

 

Is VGA supported with new kernel? If so, how ?
