@c0rnelius: Thanks for the info, I'll fiddle with the GPU in the meantime. @Cristian Apas: that hack above is necessary if you use the Xunlong Ubuntu userspace. They have replaced every hint on the OEM, which includes the GPU driver name. Hack not necessary if we simply use the Spacemit Bianbu Ubuntu userspace. I hacked an image together with this (see my site https://privat-in.de goto Downloads). It has a glmark2 score of 424 (not very fast). This is not for everybody. I compiled a standard OrangepiRv2 Armbian image with a legacy kernel and put in a Bianbu 3.01 minimal userspace as root. Details from my notes: # Image creation starts with Armbian-Orangepirv2_trixie_legacy_6.6.99_minimal.img Root from https://archive.spacemit.com/image/k1/version/bianbu/v3.0.1/ -> minimal.img -- Default LANG=zh_CN.UTF-8, change: dpkg-reconfigure locales -> en_US.UTF-8 Copy from Armbian: /etc/netplan/10-dhcp-all-interfaces.yaml, /etc/fstab, /boot/*, /lib/modules/*, /etc/modprobe.d/orangepirv2.conf /etc/modules-load.d/orangepirv2.conf Purge spacemit-flash-dtbs (and thereby remove linux-image-6.6.63*) Uploaded this image to https://privat-in.de/ (Downloads) First steps after flashing apt-get install parted parted /dev/mmcblk0 (or /dev/nvme0n1): resizepart 1 100% resize2fs /dev/mmcblk0p1 (or /dev/nvme0n1p1) apt-get install cinnamon-core glmark2-es2-wayland Reboot and login as root/bianbu (select Cinnamon/Wayland) Click on Terminal, run glmark2-es2-wayland Notes: other Spacemit K1 boards can run Bianbu without any changes, this is exclusively for OpiRV2. Also, do not try to update kernel, update-initramfs files from Armbian are missing thus the initrd needs to be massaged by hand or so. Expect oopses at every corner...

@sven-ola https://lore.kernel.org/spacemit/20260310161853.3900605-1-gaohan@iscas.ac.cn/T/#t Sometime soon-ish I'll be doing another PR with early SD card and CPU freq scaling support. The above link should at least get you boot from eMMC or NVMe.

The question is: does the auto-generated version available for download with a legacy kernel include the hack to make the GPU work in Wayland, and if not, how should I compile it? Thanks

Many thanks for your efforts. I've attempted the panvk-mesa26 + protonge configuration and tried launching Black Desert Online via the UMU launcher, but the launcher crashes immediately. When using box64 + winestaging, the launcher does start, though it only displays a black screen. If you have time, could you kindly test Black Desert Online? I'd be most grateful! My system version is Armbian 26.2.1 noblevendor 6.1.115. My device is an Orange Pi 5 with 8GB RAM. Thank you very much！

when using your fork, it worked https://github.com/fensoft/rk3528-tvbox
