UART doesn't work on OrangePi One

Recommended Posts

Hello,

I want to read data from UART3 on OrangePi One. I want to use UART3 (pin 8 & 10), so I enabled uart3 overlay at /boot/armbianEnv.txt. Now I expect to read data via minicom -b 115200 -D /dev/ttyS3 but I read nothing unfortunately. What am I missing? Any help is appreciated.

 

I'm using Linux orangepione 4.19.38-sunxi (sorry, armbianmonitor doesn't generate link)

 

Thank you,

Regards

Board: Orangepi One
