Odroid C4
#21
Yeah, looking at the Odoid forums, it looks like the Ubuntu 20.04 image is not ready for prime time on the C4:
https://forum.odroid.com/viewtopic.php?p=290824

"Known issues:
1. You can not install and run on Ubuntu 20.04 from Micro SD yet since the mainline kernel for ODROID-C4 does not support it.
2. Another couple of commands are required to finish the installation when Ubuntu 20.04 Gnome Desktop is installed. This will enable Wayland ARM Mali driver and audio output to HDMI. "

Looks like I'll have to bone up for a emmc card as well on this one.

Oh, note, with the SD card boot, running 'sudo apt-get upgrade' renders the image non bootable and has to be reflashed.

ok, got my eMMC with unbuntu 20.04 on board, and case, and its all working just fine, no GPU drivers though, and it seems this version of the OS does not have the reps to install the wayland based drivers... it reported no found when I tried to apt install. So I've decided to leave it for now, I don't really want to destroy the maker supplied version to install the user version with drivers. (though if its not done in a month or so I might)

But despite the lack of drivers its working perfectly, quite fast, gets rather hot though, might need to think about a fan in the case.. I will update it every week or so and see if drivers come along, I suspect they will since they are out there in the wild and just need a bit of translating.

Fast little machine though, even without drivers it managed a fair attempt at GLmark2, but I won't post the numbers yet as they are still far below what they will be.

If you follow the video I provided the link for, they show how to get Ubuntu minimal on the board and install the Wayland drivers. This did not work with the uSD card so I still need to get a emmc card.

This is what I grabbed from the video:

Get a minimal image
ppa.linuxfactory.or.kr/images/raw/arm64/focal
Get: ubuntu-20.04-minimal-odroidc4-20200421.img.xz

Burn to emmc via Etcher:

Install Ubuntu Desktop
$ sudo apt update
$ sudo apt install ubuntu-desktop

Wayland GPU driver
$ sudo apt-get
$ sudo apt install mali-bifrost-wayland-driver

Install GLmark2 Es2 for Wayland
$ sudo apt install glmark2-es2-wayland
$ glmark2-es2-wayland

yeah I don't want to burn over the supplied OS from Hardkernal just yet, i'll give it a month or 2, to see if HK themselves bring the drivers online and see what it can do.
