CoreELEC - How to use the Vu series displays with CoreELEC on a C4 or N2

Post by cdu13a » Wed Jun 24, 2020 6:05 am

While the C4 or N2 running CoreELEC is best enjoyed with a large 1080p or 4k TV.
It is also possible to use it with a small lower resolution display like the Odroid Vu
series displays for those that have projects in mind that need to be a little smaller
or more portable.

As of CoreELEC 9.2.3 everything should be in place to fully support the ODROID-Vu
series of displays.

Below are instructions to properly configure CoreELEC running on a C4 or N2
for use with a Vu series display at the displays native resolution.

It's recommended for a new CoreELEC install that you do the initial install with
your device attached to a regular 720p/1080p/4k TV or monitor. This just makes
it easier to do any initial setup, then you can switch to using the vu series display
after you have done your initial configuration.

Before continuing you will need to enable SSH, either when asked by the setup
wizard or by going to Settings > CoreELEC > Services > SSH > Enable SSH

Step #1) SSH into your device. The default user is root and default password is coreelec

Step #2) Remount the flash partition R/W so that we can edit the config.ini file.

Code: Select all

mount -o remount,rw /flash
Step #3) See the relevant entries below to see the changes that are required for
the vu model that you have.

[note: If you are not familiar with editing files from from the linux terminal, the following
two commands can be used to edit the the files mentioned below.]

Code: Select all

nano /flash/config.ini

Code: Select all

nano /storage/.kodi/userdata/disp_cap
ODROID-VU5
Make the following additions to the /flash/config.ini file.

Code: Select all

hdmimode='800x480p60hz'
voutmode='dvi'
Create a file /storage/.kodi/userdata/disp_cap with the following contents.

Code: Select all

800x480p60hz
ODROID-VU-5-A
Make the following additions to the /flash/config.ini file.

Code: Select all

hdmimode='800x480p60hz'
Create a file /storage/.kodi/userdata/disp_cap with the following contents.

Code: Select all

800x480p60hz
ODROID-VU-7
Make the following additions to the /flash/config.ini file.

Code: Select all

hdmimode='800x480p60hz'
voutmode='dvi'
Create a file /storage/.kodi/userdata/disp_cap with the following contents.

Code: Select all

800x480p60hz
ODROID-VU-7 Plus
Make the following additions to the /flash/config.ini file.

Code: Select all

hdmimode='1024x600p60hz'
voutmode='dvi'
Create a file /storage/.kodi/userdata/disp_cap with the following contents.

Code: Select all

1024x600p60hz
ODROID-VU-7-A Plus
Make the following additions to the /flash/config.ini file.

Code: Select all

hdmimode='1024x600p60hz'
Create a file /storage/.kodi/userdata/disp_cap with the following contents.

Code: Select all

1024x600p60hz
ODROID-VU8C
Make the following additions to the /flash/config.ini file.

Code: Select all

hdmimode='1024x768p60hz'
voutmode='dvi'
Create a file /storage/.kodi/userdata/disp_cap with the following contents.

Code: Select all

1024x768p60hz
Step #4) Power off your device.

Step #5) Connect Vu display to your device, if it is not already connected.

Step #6) Power on your device.

You should now have CoreELEC properly displaying on the vu series display.

Notes:
*The original Vu7 may need to use a usbhid quirk to get the touch input to work on it. This can be done by creating a file .config/modprobe.d/vu7.conf with the following contents

Code: Select all

# Enable vu7 touch input
options usbhid quirks=0x0eef:0x0005:0x0004
*Because the /storage/.kodi/userdata/disp_cap overrides the detection of a displays available resolutions this file will need to be removed if you attach your C4 or N2 to a display other then your Vu Series display, since it's not very likely the Vu's native resolution is what you will want to be limited to on other displays, even if it is supported by another display.

I've had this sitting as a draft for weeks, and almost forgot about it. So figured I minus well post it.
The above instructions have not been tested with every possible Vu series device, but should work.
If there are any issues let me know and I will see what can be done to fix things up.

There is also one known issue in CoreELEC 9.2.3 when using displays with a resolution lower then 720p, some 4k files do not playback properly.
This will hopefully be fixed some time in the future, however there is no eta as to when.

Hi.

I just have tested with Vu5 and Vu7A Plus. The image I use is CoreELEC 9.2.3 for N2 in the stable channel. Downloaded that today. :)

I can confirm that those two models are working very well with the latest image. Touchscreen, in Kodi GUI, 4K 60Hz playback, and bootsplash screen are all working as I expected.
Before doing the test I edited /flash/config.ini and /storage/.kodi/userdata/disp_cap file as @cdu13a guided. :)

One thing that some 4K HDR HEVC file shows a broken screen on my side. But I think this is one of the known issues as @cdu13a said.
