UART or Wifi?
Right! Will try wifi.
nothing to see in the logs, all times it report meson6-dwmac ff3f0000.ethernet eth0: Link is Up - 1Gbps/Full - flow control off. did you try the dtb from here. if no change we need to search ~250 commits what are between rc2 and rc3
will make new fresh install with new dtb provided, gimme few minutes.
btw, sorry for being so pesky… rc2 hadn’t caused any troubles before rc3 relase so Ican use rc2 without any problems
and I know it’s loads of work for you
Best for CE it will be to identify the reason to solve it properly. But we can not replicate this issue by our self so will need help by users testing images.
Maybe you can try first the nightlies to identify last working one?
http://coreelec.relkai.org/
rc2 was on 20220727
rc3 was on 20221204
There are not all nightlies archived but maybe you can identify already some working/non working versions. This will shorten our search for the reason a lot.
Just setup a fresh media with the nightly CoreELEC archived nightly builds, then set auto update in CE settings to manual. And then update manual by the archive until it is broken.
Yes Sir!

Problem resolved!
Fresh install of RC3 with provided new dtb.img file works fine with no issues.
First time I tried new dtb, I inserted it into update image so I think it has been my fault.
Many thanks for your commitment, this project is awesome.
Cheers
with the dtb from the extra zip file I provided it works?
and with the fresh virgin rc2 install with included dtb not?
rc2 with standard dtb.img works
rc3 with extra dtp.img works
rc3 with standard dtb.img does not work
all fresh virgin installations

@sesotso please update with this test image:
You can easily do it with SSH:
cd .update
megadl https://....
sync
reboot
Then after update and reboot check if ethernet is working like rc2. There is no need to exchange any dtb, it will update itself. You can confirm if the correct dtb is used by:
cat /proc/device-tree/ethernet@ff3f0000/auto_cali_idx
The result should be 0.
Ethernet works
Ethernet after waking up works
cat /proc/… returns NULL NULL NULL NULL
CoreELEC:~ # CoreELEC:~ # cat -n /proc/device-tree/ethernet@ff3f0000/auto_cali_idx

So the test image do work without issues?
It looks like a G12B rev.a issue only.
In my opinion everything is working fine.
And yes, my Beelink is rev. A.
The fix should be included in next nightly 20221223, please update with the build and report back.
No need to exchange the dtb.img anymore.

eth after waking up works with no issues
m3u playlists don’t work (unable to read playlist, reports 0 Bytes), in rc3 no problem
