UART of GPIO header

Which Khadas SBC do you use?

I am using VIM3

Which system do you use? Android, Ubuntu, OOWOW or others?


Which version of system do you use? Khadas official images, self built images, or others?


Please describe your issue below:

I checked vim3_sch_v12.pdf schematic found 40-pin GPIO header has UART definitions, but it only has UART TX/RX, no UART CTS/RTS. If I need use UART flow control, how can I do? Can the GPIO header switch multifunction for UART CTS/RTS?

Post a console log of your issue below:

Android doesn’t have this function, so it doesn’t mean anything to you.
