There is also USB 3.0, everything is fine, if you want to save the androidš
I did the update to 9.2.3 and now Kodi doesnāt start. I have the CoreELEC screen and CoreELEC (official): 9.2.3 message in the left-corner.
I can SSH into the box an I can see that the Kodi service isnāt working:
systemctl status kodi
kodi.service - Kodi Media Center
Loaded: loaded (/usr/lib/systemd/system/kodi.service; enabled; vendor preset: disabled)
Active: inactive (dead)
If I try systemctl start kodi command it hangs forever.
I donāt have any new kodi logs after the update.
How can I debug further? Thanks
How did you install the original CE that was running on your system ? If it came preinstalled or you used the Khadas tools the partition structure is incompatible with standard CE file format. In this case you should only use CE versions packaged by Khadas to upgrade, the CE .tar file will trash your install.
This issue has been encountered by Coreelec team members and they have created a solution. I suggest you go over to the Coreelec forum and search the 9.2.3 thread for the cure for your problem.

I did not encounter a problem, try also to do a full reset to the factory
Yes, specify this moment ?!
I flashed it myself on an microSD card using the official docs: https://docs.khadas.com/vim3/index.html#VIM3
For update I got a popup in Kodi, I selected the update and expecting to work.
Should I understand that the hot update doesnāt work? I have to do it manually or from scratch?
These are the instructions you need:

This looks like I have to redo all my setup from scratch.
What is not clear to me if this was a bug that broke my system or it is the state of the platform not to provide hot updates. I donāt want to do this setup every-time I want to update Kodi. Is it on the platformās roadmap to have seamless update of CE?
this question is more likely to the guys from coreelec, although I didnāt encounter a problem like yours
Coreelec is updating for CE users without this issue. Its specific to the way that Khadas handles the CE image that causes the issues. Once you migrate to the CE ecosystem you will not encounter this issue again.
Two things to note though;
-before performing a version upgrade you should always perform a backup using the CE backup tool built into the CE setup addon. This will allow you to recover your system even if you have to do a full reinstall
-I am not certain of this, but I believe that the method advocated preserves your storage partition and so system setup.
It would be best if you have any more issues that you raise them on the thread to which I pointed you.

I only now start having a better understanding of the structure of all things involved. Thanks for your help.

I actually did that and I got a 2 GB backup which once restored it did bring back just the kodi settings but not the opkg packages and personal configuration files I had in the home folder.

Unfortuantely not. It does this only if one didnāt have the fail update first. My bad here that I updated as soon as I saw the message instead of going to check if anybody has issues
After restoring my setup it seems there was an issue with the Entware setup. As soon as I renamed the /storage/.opt directory kodi starts without any issue. They said itās not supported and I didnāt listen. Too bad that these days I need 4 RPIs and one VIM3 to run lite open source services that could be run on the VIM3; I suppose itās easier to support your service in a distro instead of general integration scripts.

opkg stuff is not part of the userspace stuff so is probably borked if the System partition gets corrupted.
Have you managed to get most things back ? Best to stick to official CE upgrades when you do.

Yes, I kept the old uSD card and restored my mounted config folders for dockers which are running fine. I used opkg only for some extra tools when SSHing into the machine so I donāt really care; now I know better. Thanks a lot for the support.

Hi, guys! So far coreelec is working great on my vim 3. However I have a minor gripe with the fan, particularly the temperature levels at which it switches modes on auto. By default they are 50, 60 and 70, but even the first level is obnoxiously loud while watching a movie. The board stays below 60 even when watching 4K HEVC, so I modified the levels hardcoded in the dtb in /flash/dtb to read 60, 70 and 80. However the new levels are not taken into account, as reflected in the device tree in /sys, even after a reboot. How can I enfore my modifications ?

hi, do you have a passive radiator and a thermal pad on the bottom of the metal plate?
I have just such a combination, I donāt even think about the temperature, although I have quite extreme operation, 4K HDR 60 fps are ātorrentā online at the highest settings, in fact the processor works almost completely, and no problems!

Hi, I think you might need to rebuild the kernel or something, We had such a request very recently but it was related to Ubuntu linux, and changing the dtb seemed to be enough to do itā¦
@Vladimir.v.v I donāt have the back thermal pad, only the top heatsink and fan, but even then itās enough to stay below 60, I just wish I could up those thresholds.
@Electr1 I believe I know why itās not taken into account. The dtb seems to be shipped by coreelec (/usr/share/bootloader/device_trees/g12b_a311d_khadas_vim3.dtb) and has precedence over the one in the boot partition.
Problem is, this is a read-only squashfs and I canāt modify itā¦ Trying to find out where the fs is stored so I can unpack and modify it.
