@xiboliyadongtu Did you try Hangover (which is Fex-emu)? https://github.com/AndreRH/hangover I saw someone had a problem with a similar online game with Box64 before. https://github.com/ptitSeb/box64/issues/3073#issuecomment-3689810679

@hexdump I also have the exact constraints, I've detached eMMC from my HG680P. I've tried your u-boot using armbian and velvet's image tester, but boot of them failed to boot, and on UART I can't see anything. Any idea what should I try next ? Anyway, I managed to boot custom OpenWrt and I attached the scripts that I used to generate image run.sh insomwrt_with_vendor_u_boot.log

@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 UART login as root / bianbu apt-get install parted parted /dev/mmcblk0 (or /dev/nvme0n1): resizepart 1 100% resize2fs /dev/mmcblk0p1 (or /dev/nvme0n1p1) apt-get install gnome-core glmark2-es2-wayland adduser a-new-user adduser a-new-user sudo Reboot and login Click on Terminal, run glmark2-es2-wayland Notes: other Spacemit K1 boards can run Bianbu without any changes, this is exclusively for OpiRV2. Expect oopses at every corner... You can install cinnamon-core and use that. Make sure to run cinnamon under gdm3 b/c starting via lightdm does not work well (e.g. menu open freezes). Also, KDE plasma only with screen artifacts and xfce4-wayland simply exits immediately. No other wayland DE tested...

@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
