On 29 September 2011, Samsung introduced Exynos 4212[8] as a successor to the 4210; it features a higher clock frequency and "50 percent higher 3D graphics performance over the previous processor generation"
Hardkernel geeft ook een maandblad uit, zie website: Odroid magazine: voorbeeld: eerste nummer: Januari 2014
In het eerste nummer van het magazine staat een artikel: "Getting Started"....
Recent wilde ik de Odroid-U3 weer opstarten. Ik vond een recente Ubuntu update!

I created an image of ubuntu server 20.04 with the mainline kernel 5.4.20.

De volgende stap is het aanpassen van de hostname, zie:
Manpages.Debian.org: HOSTNAME(1) Linux Programmer's Manual
Edit /etc/hostname for permanent change.
De hostnaam is aangepast naar "odroid-u3".
Check "ssh"

In februari was ik bezig met de installatie van DietPi software op een wireless Raspberry Pi Zero 2W, zie: Pi-NAS
Onderdeel van de installatie was het installeren van een X2Go remote desktop client voor het beheer via de Dell-G15.
Resultaat: bootlog X2Go client Dell-G15
Resultaat: X2Go server Odroid-U3
Een klein probleempje: s5p_mfc Firmware is not present.
Dit komt doordat de processor is ontworpen voor een mobiele telefoon.
De video hardware is niet aanwezig in de Odroid-U3,
