@Morales MoralesThe older build where ethernet is working: https://github.com/sicXnull/armbian-build/releases/download/mxqpro/Armbian-unofficial_26.02.0-trunk_Mxqpro-h313_trixie_current_6.12.74_cinnamon_desktop.img.xz The semi-official one where it's not: https://armbian.com/boards/x96q

Just a shot in the dark, does this build work better?

Oh, my GOD ! I used the Android14 OS image from FriendlyElec google drive, and every video format I tried worked perfectly with full hardware acceleration ! Using Kodi player, this NanoPi M5 it is even capable of playing H.265 Full-4K 60fps 10bit HDR, without frame drop ! So the hardware is perfectly functional for 4K movies. The problem is the software component that is present in other OSes besides Android. Guys, I don't understand... Can't we take the drivers that FriendlyElec used in the Android14 OS image and adapt them for Armbian ? It would be brilliant to have an OS as cool as Armbian with full video acceleration capabilities ! Since I have this board, I'll gladly help you with any tests needed to make this Armbian for NanoPi M5 functional ! Just give me some ideas on what I should do... I will be your NanoPi M5 beta-testeer.

Well I gave up on it. I can't figure out how to boot anything other than armbian on NVMe and I need to boot a USB for starters. I guess I'll have to use for armbian until a cheap board with UEFI arrives. Orange Pi 6 Plus is too expensive for me.

Hi, I think swapon is not visible because you are not root. It should already be there via required package "mount". Try tu "su -" then you will "see" the command.
