Odroid C4

I seen on the ODROID C4 forum where folks are using a Laptop Adapter with a Y-cable to connect multiple boards. This might be something to look at.

Here be a 12v 5A power adapter. This should power like 2 C4s.

So, my C4 came in today and I was able to get the Ubuntu Mate 20 image loaded on an SD card and booted the C4 with it.

I used Etcher on an Ubuntu system to burn the image.

NOTE: When installing the SD card, the label faces down. I don't like that the card just under the GPIO header though.

Also, I am using a 7.5V 1.6A power adapter and it seems to be working fine. I still need to get an adapter with more amps, but so far it seems to be working.

Where did you get the image? Ahh the link gives it...excellent I'll download that and give it a try.... does it have gpu drivers?

ah

No EGL/GPU Acceleration on X11 (You have to use Minimal image to have a HW GPU acceleration on the framebuffer)


ok, well I'll hang on a bit longer... I want X11 or Wayland.

Have you seen this video regarding installing Ubuntu 20 with the Wayland driver?

Note, they are also installing glmark2-es2-wayland
I have not seen that before.

Cheers

Well, I tried what was described in the video but I could not get Wayland to appear as a desktop option and I could not get the network set they way I wanted. Ubuntu 20.04 has many differences from 18.04.

I ended up going back to the Mate image which seems to work fine outside of the typical Ubuntu crashes.

yes but it requires emmc to work, so will try it when my module arrives... am very currious to try wayland, though no idea why its better/worse than X11

ahhhkkk another 24euros in taxes for a case and eMMC, I should have used my brain and bougtht them all togeter. Much of that is tax on the postage...this better be a great board

Actually I was able to install it and run it on a uSD card.  I just had issues with the desktop not working properly so I may try another monitor to see if that was the issue.  ITMT, I've gone back to Mate which is easier to get working; I'm even able to run the OpenGL examples from RDP using xrdp on the C4.

thats interesting, it refused to boot on my SD version, maybe I should try a different card type.
