How to USB to TTL serial cable with Rock Pi S?

Hi there, I’ve just started to use the Rock Pi S and want to connect the USB to TTL serial cable. The manual doesn’t describe how to do this:

It only shows the description of an image that supposed to be uploaded, but isn’t.

Can anybody tell me where I can find this information? Would be nice if the manual could be updated with the proper information as well.



ROCK Pi S Debian system image debug console uses UART0 pins by default.

For ROCK Pi S V11 board, connection is as follows.
