@billymore https://linux-sunxi.org/Tanix_TX1 Use a toothpick or any other non-conductive stick to push the button inside the A/V connector when powering up the box. Connect a USB-A/USB-A cable to the only USB port and a host PC. https://www.slashinit.com/posts/boot-uboot-orange-pi-zero-2-using-usb-mode/ https://linux-sunxi.org/FEL/USBBoot

Board: ODroid C4 Image: Armbian_26.2.1_Odroidc4_noble_current_6.18.8_xfce_desktop.img.xz Tested OK: - Installation to SD card - Boot to desktop, login - OpenGL / Panfrost - USB 2.0 - Ethernet Not tested: - Audio via HDMI (Though alsamixer reports there's stuff there) If anything, the serial console seems rather quiet. But attached ... minicom.cap

I have two boards I can test. ODroid C4 and NanoPi M4v2. I'll pull down the C4 build and give it a go. I don't see a build for the M4v2? (EDIT - Doesn't look like the Github action failed)

I don't use multiboot. I test also to put the sd-card on the SD-Card of box and with armbian images (both - xfce bookworm or the last version Xfce of the armbian site) don't work. I test images separately, I erase the SD-Card and then try the other version image, One by One. With the steps that I already mention above. I think that I can write documents on the device and system if that boot apps like Office should work I think but I only can test it if the system armbian boot. Thanks.

You don't need to decompile.this as the original source dts is available in the Linux git source code.
