I can't boot orange pi zero 2 from first use... It displays only red LED and it doesn't change. I connected lan, SD card and power source. What is wrong with my orange pi?

Which exact image?

Debug logs?

@Fuchsia You will need to connect a serial RS232 to USB board to the debug serial port of the orange Pi (if possible) and then use a serial terminal on your computer to see exactly what the Orange Pi is doing when it is powered up?

I have a different board, but had the same problem. on @Werner's advice I got one of these boards connected it up and my board (A Banana Pro) was starting-up normally. Once I completed the initial setup over the serial debug port then everything fired up fine.

Also, yes, what exact image are you trying to put on the SD card and are you using one of the two Armbian recommended SC card image writing programs?

I find that rsb is used in place if i2c.

I have an old board and like old orengepi one plus and the new orangepi 3 lts they dosen't boot with rsb.

 

I modify the DTS for use i2c and the board boot.

 

I think that this rsb bus is buggy

 

red led is ok, you have to wait 3-5 solid minutes.

ethernet cable connected, check on your router which ip is assigned.
