Which Khadas SBC do you use?

I am using VIM3

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

Android

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

Android-13.0.0_r6

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.
