Orange Pi zero plus2 H3 problem with connecting GPIO UART to APM flight controller.

Before this I used to connect my APM 2.8.4 Flight controller to a Raspberry PI on Ground, Pin 8 and Pin 10.

Today I tried to connect it to my orange pi zero plus2 H3. Pin 9, Pin 8 and Pin 10. On armbian-config toggle UART2.

 

When i tried to connect to it using cat /dev/ttyS2 nothing came out. Once a while sent out some gibberish.

 

I set the correct buadrate at 57600 and 91600 to no available.

But I know the settings are correct because when I connect using USB through /dev/ttyACM0 it works.

I tried ttyS1 and ttyS3 nothing came out of it.

 

On Raspberry I had done this many times just by turning on the Serial Connection using raspi-config.

 

Anyone have any solution for this?
