CoreELEC 19.1-Matrix_rc1 Discussion

Try disabling all addons, reboot and check then. If it’s then OK, enable one by one until you find what’s causing high CPU usage.

I found now solution, but i will tested more hour with watching iptv. I changed cpu governor from ondemand to performance and now is cpu less used in idle and normal time. I will check temperature. From kodi 19.0 i dont see frequence in kodi.

Try to SS to the box and run:
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq

Ok, in ondemad is jump from 667 to 1704 in idle time. I really try again from zero ckean install. Disabling of addons not helped.

It will be good some ssh utility for monitoring of proceses in backroung and cpu usage

Try the command top

yes, …kodi.bin use 23,5 %

I use netdata webgui

Conclusion: is not addon. I installed again coreelec, changed cpu gouvern from default performance on ondemad, and cpu usage is 23+% in idle (in coreelec 19.0 it was max 10 % in idle). It is bug of used kodi in coreleec, if kodi.bin have high cpu usage.

For compare, logs from 9.2.7:

  • Test was on same sd card. Here are diferencess with ms word created (small my fault: i forgot enabling of wol and saved config file of remote config on sd card on 9.2.7 system, therefore is as something “new”, but dont have impact on results) : CoreELEC Debug Information_diferences.docx (53.5 KB)

Hi, sorry for my bad english.
I have Ugoos AM6 Plus.
On Coreelec 9.2.x and on 19.x Matrix sometimes there is no audio on first playback of video; it happens about 1 in every 3 times, it’s just random. If, immediately after of this issue, i play another video, the audio of new video play and if after i play the first video then the audio plays and the issue is resolved. This issue is via HDMI to TV. The audio via spdif to AVR with passthrough work fine.
Moreover when i use Kodi with Android OS also audio via HDMI to TV work fine. The random issue of no audio via HDMI is only on Coreelec.

This user have same issue:

Thanks for help!

Quite often, I get an “could not play this item; check logs”, however I can’t discern anything from them.

The “temp fix” is to reboot and the sftp-connection plays ball again, mariadb as database “btw os-server”. Everything works fine besides this.

Are there any settings, timeout?, that I can put in advancedsettings or some such?

Great work on Matrix, it’s very stable and Kodi crashes less often on daily use.

Using Mecool KI Pro as a daily driver. I was wondering if there is some way to install CoreELEC on eMMC on KI PRO? Currently, ceemmc doesn’t do anything.
Here’s the output:

ceemmc -x
Starting CoreELEC eMMC installation tool...

System is not supported: gxl_p230_k1_pro!

There is NO official support by Team CoreELEC
if you continue to run this tool!

    [2] existing backup on current used SD or USB device

Please choose one option? [1/2]: 1


Is there a firmware upgrade or something I can do to install it on eMMC or is it considered too old for this feature?

I have on second device KI Pro on emmc with Coreelec 9.2.7, some one year. I installed 9.2 and after from release to release was updared during time.

This is a bug, please use last available nightly.

Thank you very much! It is working now!

Hi, 19.1-Matrix_rc1 working beautifully on my K1pro, except for remote, which is dead. Used to work on 9.2.7. Any idea? Thanks

Maybe battery are dead? Just joking.

What did you do to get it running? There are some differences mentioned for CoreELEC 19 here (toml extension): How to configure IR remote control

If someone is interested, installing CE on the internal mmc, the second system using the standard ceemmc utility.
Only for NG devices!
In principle, there is nothing complicated. Everything is done in SSH, I used a smartphone with Terminus installed for this.
The only limitation is that almost all TV boxes are not officially supported, so the command must be run with option -x:

ceemmc -x

Installed on the available X96Max and Mecool Ki pro. They also had a stable RC1 Matrix build installed on an SD-card. With X96Max, there were no problems at all, the configured system flew into the internal memory in parallel with android and loading from the sd-card became unnecessary, and for some reason there were problems with Ki pro and the installation gave Aborted! Then for the sake of laughter, I decided to try to update to a fresh nightly build and the installation was successful. It can be noted that emmc is faster than sd in terms of reading speed, so loading both the system and all add-ons has become more fun. Good luck to everyone…

Hello, since I had problem trying to do an upgrade from 9.2.6 to Matrix V19, but wanted to keep all the customizations I did on the Aero Silvo Nox skin on the previous installation, I finally did a clean install on an 8 Gb MicroSD card, keeping the older 9.2.6 (now 9.2.7) on the eMMC card of the Odroid N2 to revert to if things went bad.

I took the advice of “thecubasekid” on the previous V19 Matrix topic and copied the Nox files and skin shortcuts from adons and addon_data, and everything ended up perfect, so thanks to thecubasekid for the tip. I finalized the setup the way I wanted, made a backup of the microSD card and restored that on the eMMC. Everything is fine, so I’m a happy camper.

Only thing is that the microSD card was a 8 Gb, but the eMMC is a 16Gb; so I have almost half of the eMMC that is not used. Checked to see what is the command I could send from ssh to expand the partition so that it uses all the available space on the eMMC, but I’m not sure of the correct command to do it. I know when installing fresh the image on the card, that command is lauched at the first boot, but I can’t find the way to lauch it afterward the way I did. Thanks

Can’t you simply make a complete backup of your present eMMC installation, then make a fresh installation on eMMC, which will be properly resized, and then restore your saved backup?
