I was absent from Odroid forum for months at least but I though maybe its a time to check Kodi Leia builds? So I tested Official latest LibreELEC (Leia) v8.95.2 BETA and BETA3 on my C2 and... horrible experience: micro-stuttering, temperature at idle so high, kernel still the same version so I'm back to LibreELEC (community): 8.2.3.1-C2 (https://kszaq.libreelec.tv/s905/8.2/8.2.3.1/)
Details regarding micro-stuttering and temperatures I have posted here: https://forum.libreelec.tv/thread/13538 ... post107178
Can you guys tell me if I might experience the same issues with CoreELEC or CoreELEC is better?

Because CoreELEC development is focused specifically on better support for amlogic based devices such as the Odroid C2, it should be a better experience for most people.

A lot of the problems that LibreELEC has on amlogic devices have been fixed with CoreELEC. However the best way to say for sure if your specific issues would be resolved with CoreELEC would be to give it a try.
https://github.com/CoreELEC/CoreELEC/releases/

A small item worth mentioning to save you some potential head scratching later, CoreELEC release files have a slightly different naming then the LibreELEC ones.
While the install img for the Odroid C2 is CoreELEC-S905.arm-x.xx.x-Odroid_C2.img.gz, the upgrade .tar files have changed to CoreELEC-S905.arm-x.xx.x.tar.
This is because CoreELEC has an improved build and upgrade system that allows for one unified .tar file for upgrades between versions of CoreELEC.

@cdu13a: thanks for your explanation. Coming weekend I will try to test CoreELEC. Do you recommend to do a fresh install or do the upgrade over the current version that I'm running LibreELEC (community): 8.2.3.1-C2 by @kszaq? By upgrade over the current version I mean the following procedure:
1. Do the LibreELEC backup
2. Install CoreELEC
3. Restore LibreELEC backup
This is how I get LibreELEC (Leia) v8.95.2 BETA just in order to have all addons, customization, Kodi settings, etc. not lost.

I would recommend a fresh/clean install.

If you want to try backing up a LibreELEC install and restoring it on a CoreELEC install you may have some luck doing so, however there is the possibility that something backed up from one may cause issues on the other.
While some things have stayed pretty close to the same between LibreELEC and CoreELEC there are other things that have changed quite a bit.
So it's hard to say which combination of customizations/settings/addons/etc... will be no issue and which will not when restoring a LibreELEC backup on CoreELEC.

Either way, probably a good idea to give a fresh install a try for a bit first that way if there is an issue because of restoring the backup, it will be easier to identify that as the cause.

Kodi 18.0 "Leia" was released today so there should be a new CoreELEC release soon including it.

Hello. Is there an easy way in CoreELEC to setup dual audio ? My setup requires to have 7.1 PCM sound via HDMIA + 2.0 sound via usb DAC. I am using LibreELEC currently and invistigating if it's worth migrating. I've tried to setup dual sound audio on libreelec with pulse audio with no luck. It only worked with 2.0 + 2.0 setup. The only way I've made this to work is dual audio patch (i've recompiled libreelec 8.2.5 with patched kodi) but it is not available for kodi 18 yet.

I've been using LibreELEC on my ODROID-C2 since the day it was released, and LibreELEC 9.0 runs like garbage on it. Too many random randoms, libreELEC doesn't officially even support any Amlogic releases anymore as they are even listed "semi official"

Switching to CoreELEC and never looking back

CoreELEC works great also and the support is magnificent.

When I try and map SMB v2/v3 shares on my C2 with CoreElec I get 'operation not permitted'. It works fine on my 8.2.5 LibreElec build.
Weird thing is I can see the contents of the shares as a 'network location'. But I cant add them as a mapped SMB share.

It's just a suggestion but you should post Bugs in our forum https://discourse.coreelec.org. it's really hard to follow all the different forums and we have a ton of support questions because our user numbers exploded with LibreELEC basically abondoning Amlogic devices.

I want to switch from my current LibreElec 8.2.5 to CoreElec 9.0.1 doing a fresh install.
However, which DeviceTree to use? Why does Odroid C2 nowhere appear in the lists?

Odroid C2 has a dedicated img.gz for fresh install. If you update you will have to update the dtb. There is only one that has odroid_c2 in its name.

Odroid C2 has a bit of a premium device status for us. We do support a generic AML installation where the user might have to change dtb bit the img.gz for Odroid C2 works out of the box.

Once you flash the machine specific image (C2) then for all future updates just UL the .tar file to /storage/.update and reboot and it will install!

I just installed the latest image on my C2 and I am liking it a lot. I am trying to set up some game emulation and am running into a problem. I installed Rom Collection Browser and all of the SNES emulators listed in the CoreELEC repository. When I start Rom Collection Browser and try and go through the setup it asks for an emulator location. What is the path to the emulator location in this image? Is it supposed to auto detect them?

Thanks
Jon

I solved my own problem. I took my emmc card out popped it into my Linux laptop and used the file browser to find the emulators. I then had to go into kodi and tell it to show hidden folders. I could then navigate to and select my emulator.

Thanks
Jon

Dear all,
I hope this is the correct place to insert my issue.
I'm writing fro Italy.
Almost since its inception I'm using Coreelec to run KODI and now I'm at the last version released 9.0.1. (greate work to all the team)
I have a strange problem to solve with Amazon VOD addon. It looks like most of the movie have not any audio track available. (video is ok)
I can't understand if it is an addon setting or something related to Kodi or inputstream adaptive. I noticed instead that many TV series work properly.
I use also Netflix addon with inputstream adaptive and it works correctly.
I didn't find any help in the web for this reason I'm asking here.
I hope in your help.
Please let me know if you need more information to understand the issue.
Thank you very much
Dami

Hi guys,

first of all, I really like the CoreELEC at its current state. Thanks to all that have contributed!

I am trying to run Java on my Odroid C2 in the background (this worked well for me back when i used LibreELEC). The problem is that I am not able to run java at all. I downloaded the latest version, moved it to my Odroid and tried to run it:

Code: Select all

...# ./java -version
-sh: ./java: Permission denied
Well, I understand that and granted execute rights but then when I want to execute it, i get a "not found" error:

Code: Select all

...# chmod a+x java
...# ./java -version
-sh: ./java: not found
Can anyone help me understand, what this error means? How can the file not be found?
I have also added an screenshot of the actions which should also demonstrate the problem quite well:

I would be really glad if anyone can help me resolving this issue.

Thanks in advance,
Thomas

Would it be possible for you to write a 'step-by-step' for a basic newbie to follow on how you achieved the Java install on the C2 CoreELEC?

Thanks would be awesome ...

Could you explain what you mean by that please? Do you mean a Kodi addon? Do you have any link of how to get started, although I am not sure that I am capable of such thing!?

I hope I don't spread too much bad practices because I am also quite unfamiliar with linux but here is what I did. I will just assume that you are able to move files to your Odroid and access it via SSH (e.g. with PuTTY):

1. Download the JDK for ARM from Oracle. Make sure you take the "Linux ARM 32 Hard Float ABI" of the "Java SE Development Kit 8u212" instead of the 64 bit version like I did.
Note that you have to create an account to be able to download this. As I am also not very comfortable with linux, I downloaded and extracted this on a windows PC.

2. Move/Copy the JDK to your Odroid. You can do this for example via the Samba file share and a simple copy command. Lets say you place it at /storage/jdk. I continue assuming this location.

3. Connect to your Odroid via SSH if you haven't done this already.

4. Grant execute permissions to the java file in the JRE directory (JRE is in a sub directory of the JDK --> we actually don't need the JDK but I didn't find a download of the JRE for ARM)

Code: Select all

chmod a+x /storage/jdk/jre/bin/java
ls /storage/jdk/jre/bin/java -ial
This should output something like this:

Code: Select all

1933839 -rwxr-xr-x    1 root     root          8112 May 30 11:38 /storage/jdk/jre/bin/java
The important part here are the "x" in the sequence "-rwxr-xr-x". These three "x" basically mean that every user has execute permissions for the file.

5. Check if the JRE is working

Code: Select all

/storage/jdk/jre/bin/java -version
This should output something like this:

Code: Select all

java version "1.8.0_212"
Java(TM) SE Runtime Environment (build 1.8.0_212-b10)
Java HotSpot(TM) Client VM (build 25.212-b10, mixed mode)
You can now run java applications by using

Code: Select all

/storage/jre/jdk/bin/java -jar yourApplication.jar
As a little bonus, I have added the bin directory to my PATH variable so i can run java applications like: "java -jar yourApplication.jar"
Hope I could help.

Kind regards,
ZinCi

The new 9.2.0 stable release of CoreELEC is now available.

For everyone on the previous stable release with auto updates turned on, you should get an update notification in the next couple of days.

For those that would rather manually update or can't wait for the new release it can be downloaded here
NOTE: just a reminder when downloading the update files, If you have an Odroid-N2 you want to use "amlogic-ng" update files, otherwise if you have a C2 you want to use the "amlogic" update files.

The release notes can be read here

Important: It's recommended that before you update that you disable any binary addons that may be started before kodi can update it's addons. such as the vfs addons like vfs.sftp. Then after the update make sure you refresh your addon repositories and install any updated addons, before re-enabling them.

The new 9.2.1 stable release of CoreELEC is now available.

For everyone on the previous stable release with auto updates turned on, you probably already have gotten the update notification.

For those that would rather manually update or want to do a new install the new stable version can be downloaded here

The release notes for the 9.2.1 release can be read here

NOTE about updates:
Just a reminder when downloading the update files, If you have an Odroid-N2 you want to use "amlogic-ng" update files, otherwise if you have a C2 you want to use the "amlogic" update files.

NOTE about new install:
I've noticed a few new users get confused about the mention of dtb files and the "copy device tree" step of the install instructions. This part of the install instructions is only relevant to generic amlogic android devices, the CoreELEC images for the Odroid-N2 and Ordroid-C2 have this step already completed for you and come ready to be used. So all you have to do to install is:
1.) Download the CoreELEC image. (The download helper will help you get the right one)
2.) Burn the downloaded image to your sd card or emmc module.
3.) Attach your sd-card or emmc module to your Odroid, then power on your Odroid.
4.) Add your media and any preferred configuration for your intended use.
5.) Sit back and relax with a snack and a drink, and enjoy using your new setup. (The most important step. :) )

Hi all.

I have a ODROID XU4 board.

I am not clear regarding compatibility of X4 vs N2, C2. Does CoreELEC support this board?

I want to use my XU4 to use LibreElec/Dreivative, supporting dvb-t2.

Thanks in advance for your comments, hints and advice.

Hi @frtorres

CoreELEC is only designed for use with devices that use an Amlogic SOC.

That means that there is support for the ODROID C2 which uses an Amlogic S905 SOC and support for the ODROID N2 which use an Amlogic S922X SOC, and pretty much any other Amlogic based device that uses an Amlogic S905 or newer SOC.

However there is no CoreELEC support for the XU4 since it does not use an Amlogic SOC, but instead uses a Samsung Exynos5422 SOC.

I Unfortunately don't know if LibreELEC currently supports the XU4 or not, or if there are any community builds that support it.

If you look in the XU4 section of the forum there are several posts that may help you get kodi running on the XU4. for example I just did a quick look and found the following.

Thanks @cdu13a for your kind response.

Yes. I already tested other kodi ports to my XU4. Unfortunately developer does not support dvb-t2 unless dvb-t2 drivers are on kernel mainstream. I got that answer.

My usb dvb-t2 unit is supported in LibreElec using drivers from cvh team member. See http://cvh.libreelec.tv/

Latest Libreelec versions usually have a DVB Drivers Configuration Addon to install these cvh drivers with a proper kernel.

Thanks again for your answer and info.

Regards and happy holidays, Francisco

Hi,

I just bought an ODROID N2 to watch my movies on KODI. I'm sort of happy with it but I have run into two problems:

The first is that there is no way to turn on the machine unless I unplug and plug the cable every time. This is very annoying. I use a usb game controller to navigate the menus, but it has no button to power up and no mapping option. I also tried Kore for Android from my phone but the wake up option doesn't do anything either. Is there anything I can do?

The second is that CoreELEC doesn't seem to want to update. Right now it says I'm on 9.2.0. but I have auto-update on and I've read it should update automatically to 9.2.1. Well, it just doesn't. So I would like to know if there is a way to easily update manually.

Thanks

As for updating manually from 9.2.0 to 9.2.1 on the N2, you can find the update .tar file in the download section of http://coreelec.org
just copy it to the .update folder on your existing install, then reboot.

If your TV has CEC you maybe able to use it to turn on the N2,

Another option would to add a button to the n2 that can be used to power on the device. https://wiki.odroid.com/odroid-n2/appli ... key_wakeup
Keep in mind that CoreELEC uses a config.ini file instead of directly editing the boot.ini for user changes, so skip the part in the above instructions that mentions editing the boot.ini, and instead edit the gpiopower entry in the config.ini,

Hi all.

I've tried to install a new copy of 9.2.1 onto my C2, and it seems to work. Except, CEC commands are not being accepted at all. Installer works, reboots, and then the initial startup screen with the device name dialogue appears. CEC just not working - have I missed something? This used to work immediately using LibreELEC.

On a side note, I have tried a nightly build - no different.

Any help would be greatly appreciated.

---

Ninja edit: problem solved. Having the device connected to a HDMI switch stops it from working.

Ok, hate posting a blind question like this, but my searches have come up dry so far. Long story short, I've been running a C2 with an older build or LibreElec for 3 or 4 years now (Kodi Krypton 17.0 I think on that side), mainly because it was in my theater, I had it stable and just left it. Had a little spare time, so decided I'd give CoreELEC a try. Clean install, the only thing I backed up from the older version was the library, everything else I reinstalled manually. The only problem I've run in to is I can't seem to get it to output 4k. Max resolution option is 1080p 60, and it seems to scale any 4k content I have to that as well. Is this a by design limitation, or is there something I'm missing?

You need to go into settings and whitelist 4K

Settings/System/Display/Whitelist

Advance needs to be enabled.

That’s the trick. It’s not in the whitelist either.

Edit: So strangely, after a few more reboots, the whitelist populated with the 4k options. When I initially was installing, I had brought the ODroid into my office and hooked up to my monitor (which is a 1080p). Maybe it just detected the max and that affected the whitelist initially or something along that line.

Edit Edit: After having a little time to play around today, it appears that's precisely it, and it either runs home to mommy or has a default. In the theater, I have a JVC RS600 projector, which is very slow to boot. Seems the Odroid, even though it's the last device powered on in sequence still boots before the projector, and as such when it first comes up only has up to 1080p even available in the whitelist. Once I reboot, with the projector already up, all of the available resolutions appear. Not sure if I call it a bug or not, but definitely a bit of a weird situation. I'll post over on the main site about it (haven't registered there yet).

For those that still have an ODROID C1+ lying around - it still makes a great little 8bit 1080p Kodi Leia v18.8 media player.
Tweaked CoreELEC over the weekend and came up with this...

CoreELEC-Odroid_C1.arm-9.2-devel-1596364098.img.gz

CoreELEC-Odroid_C1.arm-9.2-devel-1596364098.tar

Even most of the 720p Netflix Original content SW decodes just fine with the Netflix Addon.
Kodi Leia's Inputstream Adaptive really does add some great functionality, especially where I live with a suite of excellent Addons for such streaming from the Addon Wizard - Mr - Matt Huisman

I really have to applaud HardKernel here too for there excellent attention to detail with the Heatsinks and thermal engineering. :D

HW decoding doesn't work on iptv, right? Black screen on every channel with it on. Even on 480p channels.
Odroid C1.
