If the Radxa zero reboots with ssh then Debian starts up and runs.
If i disconnect the power and reconnect the Radxa starts up and runs.
If i start the Radxa without keyboard then the Radxa is not booting.
When i choose boot then the Radxa starts and runs.
If you have anything connected to pins 8 or 10, disconnect them and see if that makes a difference.
There is nothing connected to pins 8 or 10.
It seems like it is detecting some kind of input when the keyboard isn’t connected. As a last resort, you could disable the 2-second delay in U-Boot so it will not give an opportunity to cancel autoboot.
I have same problem then I connected external power supply and it solved my problem
I have found a solution.
The pins 8 and 10 where floating, connected them with a resistor 47K to ground solved the problem.
The Radxa starts up now
