I have exactly the same issue. Cannot boot after upgrade, also newly flashed image won't boot with exactly the same trace. I compiled latest upstream U-Boot v2025.04 as described here (Pre-Built FIP variant). https://docs.u-boot.org/en/latest/board/amlogic/odroid-c2.html Then I patched Armbian image with latest U-Boot. dd if=u-boot.bin.sd.bin of=Armbian_25.2.1_Odroidc2_bookworm_current_6.12.13_minimal.img conv=notrunc bs=512 skip=1 seek=1 And that works for me, system boots just fine

I returned to this project after some time. If there are people still interested in this small POE capable board, I have created a repository with armbian userpatches and build instructions. There is also binary firmware (built from current main - 23.11) available for download on the release page. https://github.com/loblik/bananapi-p2-zero-dts If you find some bugs, you can file an issue on github. I've also sent device tree patches upstream again.
