(RESOLVED) No video out (or boot fails) on Pine A64

Troubleshooting
1

Hi.

I installed the latest DietPi image for the Pine A64 onto an SD card and tried to boot.

There was no video output, and nothing indicating the machine was running.

What should I expect for a first boot experience?

2

After some experimentation, I saw that it was claiming an IP address.

I let it run for a day or so, and eventually I could ssh in. Is the video out expected to be broken/nonfunctional?

It’s not much of an issue, as I was planning to have it run pi-hole headless, but it would be nice to know that the video isn’t expected to work.

Still more notes:

After logging in, there was a lengthy update process, and now most things are pretty broken.

apt-get upgrade fails with a bunch of errors about the server certificate verification failing:

My experience matchs yours, I have pretty much given up on dietpi
I got NO video with 6.13
With v145, from pine site, I had console video,
but xrandr and X thought there was no screen (maybe because I was root?)
i suppose one could overwrite the dtb with a working one, eg q4os or armbian

Hi all,

Apologies for the issues you are experiencing.

I’ve just updated our PineA64 image, which contains the 0.6.2 kernel/uboot from Ayufan.

Please try the updated image and let us know if this resolves the issue:
https://dietpi.com/downloads/images/DietPi_PineA64-ARMv8-Stretch.7z

EDIT: Verified HDMI output is fully functional

Sorry, it is still not right
Like 415 console video is OK *, but X says
Fatal server error
No screens found

  • in dietpi-config, display options, change resolution (as 613)
    it shows no resolution, before or after a change
7

Farther, X can be made to work,
edit /boot/uEnv.txt, remove comment from

disp_screen0 = lcd or hdmi

And now I see I am losing my mind,
the comment is restored after a reboot,
but X still works

Hi,

You’ll need to edit the file on the DietPi RAMdisk location:

/DietPi/uEnv.txt

Changes made there, will be saved after reboot.

HDMI resolution not being applied in DietPi-Config will be fixed in v6.15 update.

Please download the latest script to resolve now:

wget https://raw.githubusercontent.com/Fourdee/DietPi/testing/dietpi/dietpi-config -O /DietPi/dietpi/dietpi-config

Good day
Yes, your script fixed Change resolution-> current being blank
That is, when I opened change resolution it was blank, then selected what it currently was,
then the setting was displayed correctly.
Thanks
