Had to debootstrap trixie because depmod version mismatch. Wifi 2.4 + 5 GHz + BT headphones, keyboards all work. USB is still stuck in plain charge, no micro SD. According to Gemini 3.1 Pro which I have been using, Imagination Technologies (PowerVR) BXM-4-64 MC1 would need 6.12.x kernel or newer which I have not been able to boot yet. This actually feels a bit faster than the Teclast Android even though without accel youtubes playback is quite slow. Battery life probably 5+ hours.
 
aliexpress.com/item/1005009649297050.html keyboard + touchpad I have is a bit shady miss-clicks a bit once in a while. Might have to AI haxor some software filter to get it behave a bit better but that should not be that big of a deal. I have kind of already made up my mind, this ain't going to boot Android anymore, have to see if I grab another one at some point.
 

Okay slight update, I have successfully booted https://forum.armbian.com/topic/56130-radxa-cubie-a7aa7z-allwinner-a733 linux 6.6.98-vendor-sun60iw2 kernel and debootstrapped Bookworm (Debian 12) on it using userdata as root fs.

Basically I got in using:

aliexpress.com/item/1005010529282186.html in 1.8v mode(important!)

And fiddling with the u-boot endlessly after i first sabotaged the auto-boot process.
Display is alive, usb subsystem does not work, does not probe. Wifi would be next so I can ditch the tf uart. All your bases belong to us, resistance is futile!

My recent RK3588 kernel adventure:
- dual-core H.265 (HEVC) encoding working live at full 4K@60 on armbian-build edge kernel (6.19-rc8) for Rock 5B[+] and Orange Pi 5 Ultra.
- fix for setting HDMIRX EDID (this didn't work in mainline on any of my tested hardware)
 
This is out-of-tree (practical focus over upstream goals), but it's stable and producing clean bitstreams.

Feedback welcome. 

On vendor kernel you need to enable overlay https://github.com/armbian/build/blob/main/extensions/mesa-vpu.sh#L18-L28
 
 
mainline based gnome desktop + apt install kodi (just tested 4k/H264 video works without any problems)

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...
