How to change the UART port to UART0 for debug console in Rock Pi S?


Recommended Posts

Posted

Hello,

 

I am quite new to armbian build system. I have rock pi s v13 hardware. I want to change the default UART2 serial console port in Armbian for Rock Pi s to UART0. The reason is I need hardware flow control with one of my serial port. And UART1's RTS/CTS are muxed with UART2. And no other port exposed on Rock Pi s have the hardware flow control pins.

 

Please guide me how I can achieve this.
