I ran into some trouble. I managed to boot the USB and then used armbian-config to flash the image to internal eMMC. However the script copied the USB UUID instead of the MMC UUID so now the MMC won't boot. I need to edit the MMC and change the UUID.

Thanks for the script @sven-ola. I got the R2S booted from USB. I had to tweak a few minor things. Where did you get the Ubuntu boot.cmd? usb start setenv devtype usb setenv devnum 0:1 setenv prefix boot/ setenv fdtfile dtb-6.6.99-legacy-spacemit/spacemit/x1_orangepi-r2s.dtb #setenv fdtfile spacemit/k1-orangepi-rv2.dtb setenv bootargs "console=ttyS0,115200 root=/dev/sda1" ls ${devtype} ${devnum} ${prefix} load ${devtype} ${devnum} ${ramdisk_addr_r} ${prefix}uInitrd load ${devtype} ${devnum} ${kernel_addr_r} ${prefix}Image load ${devtype} ${devnum} ${fdt_addr_r} ${prefix}/${fdtfile} booti ${kernel_addr_r} ${ramdisk_addr_r} ${fdt_addr_r}

Wrote a script to change an Armbian desktop system for Spacemit GPU drivers and Chromium (attached). Tested with the two pre-installed Gnome images on my site (see https://privat-in.de/ goto Downloads). Some testing results: Spacemit offers Ubuntu noble and Debian trixie *.deb from their Bianbu site http://archive.spacemit.com/ For us, main diff here is Noble=chromium (Spacemit customized version) and Trixie=chromium-browser-stable (older and not customized). We need Wayland for the GPU, X11 does not work. With lightdm, each Wayland login freezes. Thus use gdm3. With gdm3, Xfce4 exits immediately, Kde-plasma shows drawing errors, Cinnamon works to some extend, e.g has video placing and window sizing problems. So the only useable GUI is Gnome. With Chromium under Gnome we can watch Youtube with 1080p (video / audio sync should stablize after some seconds). When doing this, CPU temperature is up to 75°C from the ususal 65°C, power is 4 Watts from the ususal 3 Watts. Script should work on other Spacemit K1 boards as well. If you miss some package from Bianbu, write a wishlist or make an PR on https://codeberg.org/sven-ola/spacemit-mirror spacemit-gpu-addon.sh

Hello! I'll take the topic a little away from the main direction, but the question will be in the framework of game testing: is running games through the ps2 emulator (aethersx2) a dead end? When you turn on the MALI-610 on aethersx2 (need for speed underground), the video loads well (60fps, 100%), but there is braking on the screensavers, the sound also stutters and the control is noticeably delayed. When switching to Open GL, the screensavers load quickly, the sound does not stutter, the controls are clear without delay, but the video goes with slight drawdowns, the picture and sound twitch, but very rarely (while the video has an average of 55-60 fps with a percentage of 70-90%).I tested everything on the armbian 26 installed on the sd.

@xiboliyadongtu How was it going?
