Hi there!
I've just compiled from armbian buil tools a new image for Orange Pi 3 LTS. Then flash it on sdcard, anything was well, but armbian doesn't start at all. Nothing on the HDMI, nothing on the debug serial. Also LED doesn't light. I've tried two images: ubuntu jammy with GNOME and next case XFCE. Both cases didn't work. I've downloaded prebuilt image from armbian.org and it starts well. In my opinion, some problem with custom images in u-boot. but I don't know how to give a diagnosis.
