LibreELEC ODROID-U2/U3 support

Hi,

My Odroid U3+ has worked well over the last few years but now it is outdated and no longer supported I am considering my options:

Should I attempt a kernel reconfiguration? However, I do not have a Linux based pc which appears to be what is needed. I only have a MacBook Pro an old OX

( to be honest, I am daunted by the seemingly complex and time consuming task of kernel rebuilding).

OR

Should I simply buy a later version like the XU-4?

While there are obvious benefits for being able to rebuilding a kernel, I do not have the skill or ability and would prefer an easier option if available.

Any advice would be appreciated.

I have two EMMC cards so I am able to backup my existing OS.

Thanks in advance.

Hi,

first I wanny say thank to you fraggle for doing such a good job.

I am trying out your image on my Odroid U3. And have several issues:

1. resolution:

kodi boots up with 1920x1080p and I am not able to change it via the menu. (Menu options disabled). The native resolution of my Beamer is 720p but the odroid is connected via a Denon AVR 1912.

I tried several options in boot.ini to change to resolution to 720p but without success. I could change to resolution when kodi was running via ssh and xrandr-Command. There was still a picture after that but the GUI was somewhat broken and didn't resize properly.

Does anyone know of a way to force a resolution? Maybe xrandr-command at startup? Or what exactly to put into boot.ini?

I was unable to configure the Denon AVR to demand input at 720p. There are no HDMI options like this at all :-(.

2. CEC

I hoped that it would be possible to control kodi with my Denon AVR Remote. But nothing has worked so far. I was playing around with the cec-client command on the SSH shell to see if I get an error message, but it say that there is no link. I edited the hdmi_cec_config-File and tried to set sensible settings in the CEC plugin but I don't know exactly what I am doing...

Can someone recommend a CEC tutorial to get me started?

There are a few minor things (screen flicker in menu animations, spotify addon, standby activation), but those are the two main problems that keep me from throwing out my old satellite receiver.

Thanks a lot again and have some nice holidays..

That is exactly what I tried. But the resolution is still 1080p:

kodi:~ # grep 1280x720 /flash/boot.ini
#   setenv video_output "video=HDMI-A-1:1280x720@60"   :  720p (Use connected display's EDID)
#   setenv video_output "drm_kms_helper.edid_firmware=edid/1280x720.bin"  :  720p (Use system EDID)
#setenv video_output "video=HDMI-A-1:1280x720@60"
setenv video_output "drm_kms_helper.edid_firmware=edid/1280x720.bin"
kodi:~ # xrandr
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 4096 x 4096
HDMI-1 connected primary (normal left inverted right x axis y axis)
   1920x1080i    60.00 +  50.00
   1920x1080     50.00    60.00    24.00
   1280x720      50.00    60.00
   1440x576i     50.00
   1440x480i     59.94
   720x576       50.00
   720x480       59.94
   640x480       60.00

The device is not directly connected to a TV, but to a Denon AVR. There it is on HDMI Input 1. So this should be correct?

# cat /storage/.config/cec-hdmi-port.conf
CEC_HDMI_PORT=1

With Kodi CEC settings you mean "System Settings -> Input -> Peripherals -> CEC Adapter -> Physical address (overrules HDMI Port)"? Regardless of what I configure there, after a reboot it is set to 0 again...

Thanks for your help!

Someone can help me? Could you tell me howto install LibreElec on my odroid U3 EmmC?
Already tried without success (LibreElec seems doesn boot) 2 ways:

dd if=LibreELEC-Odroid_U2.arm-8.2.2.img of=/dev/sdd bs=4M

and with LibreELEC.USB-SD.Creator.Linux-64bit.bin selecting and writing the image.

PS: the sd card version works

Thanks in adv guys!

I bet your EMMC hidden bootloader doesn't match your image (I don't know how to better explain it). You need to do a eMMC bootloader recovery. Here a look here how to do it: en:emmc_recovery_xu3 [ODROID Wiki]

Cheers,

p.s.: I'm still desparate for news about a forced resolution

Quote from fraggle

Hello dear ODROID-U2/U3 users !

I've finally been able to make LibreELEC 8.2.x stable images for ODROID-U2/U3.
They're available at the usual place: Index of /~fraggle/download/libreelec/Odroid_U2 and can be installed with the LibreELEC graphical installer.
They come in two flavors: one image for SD-Card, the other for eMMC module, hence the two directories.

Fixed issues:
- Slowness when watching a video;
- Installing LibreELEC addons is now possible;
- Default configuration for the CEC is HDMI port 1. If you want to change it, you'll have to edit /storage/.config/cec-hdmi-port.conf;

- Horizontal synchronization issue that might sometimes divide the screen when using MFC hardware codecs (fixed as of 8.0.2 release).

Known issues:

- Choppiness during videos playback;
- Version upgrade is not automated and should be done manually (but it's really easy to do).

Stable version:

Version 8.2.2:

- SD image

- SD update tarball

- eMMC image

- eMMC update tarball

Version 8.2.1:

- SD image

- SD update tarball

- eMMC image

- eMMC update tarball

Have fun !

I just picked up an Odroid XU4. I'm curious to know if this will work with the XU4 model?

Hello everyone!

I am currently working with the ODROID-U3 platform and there were problems with launching

I use for SD SD image Version 8.2.2

uart output is as follows:

if someone knows something tell me how to fix it

hi!

I have odroid u3. tried with last 8.2.2 - there are some incompatibility with spotify plugin. Rest of features seems workable, but I stopped on this audio problem..

Sound just gone from whole kodi if I am starting spotify, and it starts to play, but no sound, and no sound after exit spotify..

Sound back after reboot (till I will start spotify).

All this via hdmi. Don't know how to switch to 3,5 jack, maybe need to try. But anyway, problem with hdmi sound stay.

How to fix this? How I can debufg this issue? I am not so familiar with kodi, but ok with linux ssh.. Where to look and what need to enable to get debug output?..

Thanks!

also, sound back to kodi (I mean system sounds in menu) without reboot if I am starting to play some other media, like youtube.

GitHub - marcelveldt/plugin.audio.spotify: Unofficial spotify plugin for Kodi

This plugin works without issue on all RPIs and x86/x64, but on odroid u3 no sound. It connects ok to account and looks as playing.

Thanks for the build fraggle! It works really well for the most part. Not sure if you're still working on this since it's been a while since the last update, but I've noticed something super-strange and I figured I'd just post the issue here, maybe someone else will have some pointers.

When I boot up this build, it defaults to a resolution of 1920x1080. I prefer a lower resolution, partly because it will give me better performance, but also because my odroid is hooked up to a CRT through an HDMI->RCA box and the downscaling works better when starting from a lower resolution. So I've edited autostart.sh to switch the resolution to 720x480 with xrandr. This works, but when I start a video in Kodi, it is really choppy. Probably less than half the intended framerate. Interestingly, the choppiness goes away if I bring up the HUD, then everything is absolutely smooth!

Even more interestingly, If I use xrandr to change the resolution again (while Kodi is running), the choppiness also goes away! Any resolution except the one I launched Kodi with is smooth! But of course, Kodi doesn't adapt when I change the resolution with xrandr, so I either get a tiny Kodi in the corner of my TV or I only get to see a portion of the Kodi display. But if I change the resolution back to the one I started Kodi with, the choppiness comes back, and if I restart Kodi (systemctl restart kodi) to force it to adapt to the new resolution, the choppiness also comes back, there is no way to win here!

I also see these two lines in the kodi log when I change the resolution, I assume this is why Kodi doesn't adapt to the new resolution:

00:23:01.764 T:3017331264   ERROR: CXRandR::Query - unable to open xrandr xml
00:23:01.764 T:3017331264   ERROR: WinSystemX11::RefreshWindow - failed to query xrandr

This is on an ODROID U2. Anyone else seen this? Any ideas?
