Hi again, So sorry to have left this hanging, due to lack of time. I have been trying successive updates since posting this, without the issue being resolved, but have now confirmed that this is kernel or device-tree related. Using armbian-config to load kernels, I can say that the problem originated some time between kernel 6.1.104 (02/02/2025) and 6.6.750 (03/02/25). dmesg output looks similar with and without the problem, as does /proc/device-tree, but I can post any specific output here if anyone can suggest what to look for. 6.6.750 keeps the backlight and a noisy/gray screen, while the screen is black (with backlight showing in the corners) with later kernels, suggesting a further change around 6.12 (tbc) Unfortunately I can't see where to find any armbian intermediate kernels / device-trees, so would be very happy if someone could point me at a repo. where they might be available. Failing that I can try to locate kernels from alternative sources, or compile my own, but it would be good if I could keep as much the same as possible (including any Armbian patches and the armbian dt packages.)

Hi, I'm trying to build the Armbian for Rock64. Host machine is Ubuntu 24.04 AMD64 (but it is running in VirtualBox under Windows). Build fails with the following error: [🐳|🌱] Deploying qemu-user-static binary to chroot [ qemu-aarch64-static during image-early ] [🐳|🔨] '/usr/bin/qemu-aarch64-static' -> '/armbian/.tmp/rootfs-232e77ba-e6ab-4067-8029-afd44bd1d0b9//usr/bin/qemu-aarch64-static' chroot: failed to run command ‘/bin/bash’: No such file or directory [🐳|💥] Error 127 occurred in main shell [ at /armbian/lib/functions/rootfs/distro-specific.sh:276 create_sources_list_and_deploy_repo_key() --> lib/functions/rootfs/distro-specific.sh:276 extract_rootfs_artifact() --> lib/functions/rootfs/create-cache.sh:130 do_with_logging() --> lib/functions/logging/section-logging.sh:81 get_or_create_rootfs_cache_chroot_sdcard() --> lib/functions/rootfs/create-cache.sh:90 build_rootfs_and_image() --> lib/functions/main/rootfs-image.sh:14 full_build_packages_rootfs_and_image() --> lib/functions/main/default-build.sh:36 do_with_default_build() --> lib/functions/main/default-build.sh:42 cli_standard_build_run() --> lib/functions/cli/cli-build.sh:25 armbian_cli_run_command() --> lib/functions/cli/utils-cli.sh:136 cli_entrypoint() --> lib/functions/cli/entrypoint.sh:208 main() --> compile.sh:50 The /bin/bash (/armbian/.tmp/rootfs-232e77ba-e6ab-4067-8029-afd44bd1d0b9/bin/bash) seems an ARM64 and this might be the reason for "failed to run". Is this a known issue? Can I fix it? I've tried to avoid using chroot in this line, the build goes forward but fails with similar error later.

Furthermore, today I built an Ubuntu desktop PC, and flashed a build onto an SD Card. The resultant installation has only ONE partition. No Windows involvement whatsoever Same with a USB flash drive (to eliminate the SD card adapter). So where do we go from here?

I think I have a partial success but I'm struggling to get anything but white on the red display! Will update when I have more results. panel-mipi is loading, and Card-1-SPI appears under /sys/class/drm/ which is very promising. Verified that /lib/firmware/panel-mipi-dbi-spi is still present, still patched with Kungfupancake's init, and is loaded according to lsmod (as well as dmesg) My current DTS: Edit: I installed XFCE to test, and strangely this has caused dmesg to throw errors related to panel-mipi. I had these same errors when panel-mipi was missing from /lib/firmware but it is still present there.

I tried the edge kernel, but the image became distorted. With extended use, it produced kernel artifacts.
