Upgrade to Armbian 25.11.2 successful.

Yes, it is a custom Armbian image (no coding needed) Download the Armbian build system from github Select panel-mipi-dbi to be a kernel module (M) Choose Trixie, minimal (the greeter+desktops available in Armbian need to be pure wayland, but the greeter is not) Try the DTS and firmware file again I will try to explain better tonight Are you sure you meant Linux 6.1.31? My opiz3 is running 6.13.x or newer

@wolf7250fyi: I upgraded my Helios4 from OMV6 to OMV7 RC1 in February 2024 already. Upgrade went smoothly. But after that further OMV updates were not possible, solution found at https://forum.armbian.com/topic/23465-apt-get-update-fails-with-public-key-errors/?do=findComment&comment=178626

By helping cleaning gigantic Allwinner patchset so we can upgrade it to 6.18.y and merge already prepared Cubie a5e https://github.com/armbian/build/pull/8831 Then it become easier.

@Maxim Shell it’s possible to boot using USB OTG. You’ll need the latest u-boot. You can use my mainline build. Not sure if your stick has secure boot enabled. You can remove the secure boot patches if you don't need it. https://github.com/NickAlilovic/build/tree/mainline/patch/u-boot/u-boot-mainline git clone https://github.com/NickAlilovic/build.git --branch mainline cd build ./compile.sh build BOARD=transpeed-8k618-t BRANCH=edge BUILD_DESKTOP=yes BUILD_MINIMAL=no DESKTOP_APPGROUPS_SELECTED=browsers DESKTOP_ENVIRONMENT=xfce DESKTOP_ENVIRONMENT_CONFIG_NAME=config_base EXTRAWIFI=no KERNEL_BTF=no KERNEL_CONFIGURE=no RELEASE=bookworm https://linux-sunxi.org/FEL/USBBoot#Mainline_U-Boot_.28v2015.04_and_newer_versions.29 build/cache/sources/u-boot-worktree/u-boot/v2025.10/spl/u-boot-spl.bin You can mount the compiled image to get the other files. sun50i-h618-transpeed-8k618-t.dtb uImage boot.scr I haven't done this before.
