Amlogic-no Discussion

My MINIX Neo U22-XJ downloaded the latest nightly (20250607), overwrote dtb.img with the its g12b_s922x_minix_u22xj.dtb and of course I got the static screen of death, so obvs it’s not yet fixed.

Is there anywhere else that I should be logging this, given this box is on the supported list at coreelec:minix [CoreELEC Wiki]? As before, if someone can advise how I can obtain useful debugging info, bearing in mind the SSOD appears before the CE logo, then I’ll do my best.

The only possibly useful piece of info was that I booted into the built-in Android to show the Neo U22-XJ firmware version - which is Build 20211105 - V008.

When back in CE I was rewarded by a green tint to everything, which I understand is something to do with Dolby Vision being activated by the built-in Android. But it went away after some more reboots.

Try run command dmesg and after photo taked and upload there all of errors from logs. Somebody had trouble with drb and for fixing was good only change of dtb from build of 20 december 2024. But first try photo taked errors with original dtb.

mr-b · 9 June 2025 19:43

As noted several times before and for the final time now, how can I “run command dmesg” with this after the Minix splash screen i.e. no evidence of starting any CE boot process?

atirage21 · 10 June 2025 01:38

Ok. Try put there dtb file from .tar file of NO build: Index of /Amlogic-no/CE-22/20241220/

mr-b · 10 June 2025 11:31

Yes as noted before the dtb from that build allows CE to boot OK.

But it has these issues:

switching from 1080p to 4k results in messed up display

no audio output with SPDIF or either of the HDMI settings

the refresh rate value disappears in the UI

The above works fine with CE21.2.

I enabled debug logging with the 20241220 dtg, did a restart and of course it downloaded the new build and crashed - doh! Then I copied the old drtg again and made sure I switched update to stable only. The logs are at https://paste.coreelec.org/FreezingFlagpole.
In case it’s of any use I also pasted the crash/config log at https://paste.coreelec.org/DoughTricking.

Happy to try any builds, but surely someone must know what has changed in the device tree since 20241220 build to prevent it booting?

The MIK4.3Build3107 is no longer available on 4PDA.

emveepee · 10 June 2025 15:05

I used the standard amlogic unpacker to get the .PARTITION files and 7z to get the file from video_a.ext but I don’t know use it without building a full image.

atirage21 · 10 June 2025 15:23

There are many information (we must wait on answer from developers of CE) in experiment combination of old dtb and actually build for increasing of newer builds without succesfull start at newers kernels of CE22NO:

Maybe is something missing in newers dtbs which was in old dtbs:

Maybe is this issue with some TV if is not good supported higher resolution as 1080p60hz
Jun 10 12:13:01.393309 CoreELEC kernel: [drm] am_meson_crtc_atomic_enable-[0] in: new[2160p60hz], old[1080p60hz], vmode[5-5], uboot[0]
Jun 10 12:13:01.393345 CoreELEC kernel: [drm] am_meson_crtc_atomic_enable-[0]: enable mode 2160p60hz final vmode 0

Only as experiment try change this VOUT mode (with delete of “#”) in config.ini to and use newer dtb: In my case this test not helped me with short time noise.
vout=‘1080p60hz’

It is possible use splash og NG in build of NO with some easy way ?

I will be try fix of short booting noise which was not on CE21NG on my device.

mr-b · 10 June 2025 16:49

Tx for the analysis!
In case it helps for here are the logs for CE21.2 by way of comparison.
For some reason they failed to upload initially but they eventually worked.
https://paste.coreelec.org/MarryingCrates
https://paste.coreelec.org/ExpiredBoone

Also there’s no issue with my TV as it displays 4k@60Hz fine with CE21.2.

atirage21 · 10 June 2025 16:56

There was issue at CE21NG

ASoC: Failed to add I2SIn CLK: -16

which is not now at ce22NO at your device. This “I2SIn CLK” is not in log of CE22NO.

gjstroom · 10 June 2025 18:24

You need to register and must bypass the Russian captcha. Once registered you can download it. I used chatgpt to translate the handwritten in Cyrillic script.
You download a file called MIK4.3β.zip
The file you download has the following name:

MIK4.3&#946;.zip

ragico · 10 June 2025 18:47

Thanks All done. Replaced the ucode.bin by the one found in TOX3 firmware.Now how can I create the new firmware img from the folder created by MIK4?

mr-b · 10 June 2025 21:13

RE:

vout=‘1080p60hz’

I tried this but no change was observed i.e. a still static noise screen on boot.

atirage21 · 11 June 2025 01:57

Have you possibility connect this device to other tv device or hdmi monitor ? Lg tv had also issues with coreelec in past.

mr-b · 11 June 2025 09:25

I’ve tested it on a Lenovo 4k monitor and the same static displays.

gujal · 11 June 2025 23:07

awaiting with bated breath

atirage21 · 13 June 2025 15:42

@Portisch some idea for help him ?

With older dtb from december 2024 he have booted device at ce22no with logs here, but with recent dtb is this minix box invalid.

vpeter · 13 June 2025 16:56

Build 20241220 works but next one not (20241224)? Or which one is first which doesn’t boot?

Also by using MIK4, use the file - pack menu option !
