Hello @4A studio. The armbian-config tool may change large parts of the system configuration without a real "undo". I am not sure if I understand your situation correct: Board does not boot. You see UART output but no UART login prompt? Board is booting. But you don't see a live picture on your HDMI monitor?

Hey @armfan. UUID=63ee7593-e111-4547-ac2f-6bdb8519ce11 was read from /boot/extlinux/extlinux.conf which is correct for the edge/7.1.0rc3 image. However, something must be wrong with your SD card if u-boot can read UUID from extlinux.conf, but kernel does not find corresponding file system on the same boot media. This is the expected kernel startup : [ 0.000000] Booting Linux on hartid 0 [ 0.000000] Linux version 7.1.0-rc3-edge-spacemit (build@armbian) (riscv64-linux-gnu-gcc (Ubuntu 13.3.0-6ubuntu2~24.04.1) 13.3.0, GNU l [ 0.000000] Machine model: OrangePi RV2 [ 0.000000] SBI specification v1.0 detected [ 0.000000] SBI implementation ID=0x1 Version=0x10003 [ 0.000000] SBI IPI extension detected [ 0.000000] SBI RFENCE extension detected [ 0.000000] earlycon: sbi0 at I/O port 0x0 (options '') [ 0.000000] printk: legacy bootconsole [sbi0] enabled Loading, please wait...

@hmoob What part do you need clarify? I can help you but I need more information.

Providing logs with armbianmonitor -u helps with troubleshooting and significantly raises chances that issue gets addressed.

I have the same issue than @1111Windows had back in March. That's because I chose the wrong option in armbian-config. How do I revert to original (or, at least, working) u-boot? UART connection through putty is working.
