I think the LED is always on by default and doesn't blink.
You can try kernel 5.15, I'm using
Armbian-unofficial_25.11.0-trunk_Radxa-cubie-a7z_jammy_legacy_5.15.147.img
Since I don't have any TTL modules or display adapters, I directly followed the instructions at https://docs.armbian.com/User-Guide_Autoconfig/ to set up the wireless network. After powering it on and waiting for a while, I could directly access SSH.
Hope this helps.
