Success: tested RV2 with GPU on Armbian-noble-nightly. It's a bit hacky but should work. I created a mirror of the relevant packages from Spacmit/Bianbu. Only packages with source, specific to k1x / video / gpu plus chromium. Mirror project is here, in case you want to mirror yourself or miss a package: https://codeberg.org/sven-ola/spacemit-mirror After getting up Armbian-noble-xfce4-nightly on your Spacemit/K1 board (that includes Ky X1) Add mirror repo to /etc/apt/sources.list.d/sven-ola.sources (Note: this is experimental) Types: deb deb-src URIs: https://privat-in.de/armbian Suites: noble Components: main Signed-By: /etc/apt/trusted.gpg.d/sven-ola.gpg Get my repo key with wget -O /etc/apt/trusted.gpg.d/sven-ola.gpg https://privat-in.de/armbian/key.gpg Give the mirror some weight, add an /etc/apt/preferences.d/sven-ola file Package: * Pin: release o=Sven-Ola Pin-Priority: 1000 Install GPU support apt-get update apt-get install img-gpu-powervr apt-get dist-upgrade Note: this will downgrade mesa-25.x to mesa-24.x from Bianbu/Spacemit Install a Wayland-enabled GUI (tested: gnome) apt-get install gnome-core systemctl disable lightdm If asked, select gdm from gnome instead of lightdm from xfce4. After rebooting, click on your user, then stop and select Gnome with the lower right gearwheel icon. I also installed glmark2-es2-wayland to check if that runs. It shows 417@800x600 which is faster than software mesa...

I just tested the latest Armbian distros, Armbian 26.2.0-trunk.493 XFCE and Armbian 26.2.0-trunk.493 Minimal / IOT, and none worked. Then I tried Radxa system images, rock-4se_bookworm_kde_r4.output_512.img.xz did not work. So I got confused because my Rock 4SE v 1.53 SBC worked a long time ago. Found backup of old boot image, which I used with the NVMe drive, because it could not boot on its own. And do you know what? Finally, I saw a picture on the screen with boot log information, which made me happy because it proved my SBC had not died. Then I started looking at some old system images for this board and found one which is booting, it is rock-4se_debian_bullseye_kde_b38.img.

I will try!! @Lamerjack

I`ll already done it. Switched to original Btt image. Understand what that board is didn`t love any sd-card. I`ll stopts on AP32GMCSH10UB-RA card. If card didn't made friends with the board it not boot,reboot`s,power off, halt`s.... IO pins i didnt use.... I`ll swithed to ch340 as uart, because it`s understand 3.3 and 5v levels. The board only 3.3 CAN i use on RP2040+can chip, what cost only 5$(in total), not 15$ for btt can. in a end of can bus i`ll use EBB42 so it`s have all i need.... It`s about I2C bus. Thats my story If u need help, free to ask. I`ll will help if i coud
