Rock Pi S - USB C as Virtual COM Port

General Discussion

Hi,

I’m trying to get the USB C port of a Rock Pi S to appear as a virtual COM port on a windows PC. I was trying to follow the following instructions but have not had any luck:

  1. Add this to /boot/config.txt:

Code: Select all

dtoverlay=dwc2,dr_mode=peripheral
  1. Add this to the end of /boot/cmdline.txt:

Code: Select all

modules-load=dwc2,g_serial
2

These are settings and config files for RPi device and might not fit for RockPi

Without an adapter this will not work, I think.
Or do you want to use also an USB port of the Rock Pi S and not the GPIO?

Personally I use an adapter like this https://www.bing.com/search?q=UART+USB+adapter&qs=n&form=QBRE&sp=-1&lq=0&pq=uart+usb+adapter&sc=8-16&sk=&cvid=C015C8047DA74C52ADAD1BA4EAF659E0&ghsh=0&ghacc=0&ghpl=
and Putty recognizes it as a COM port when connected to USB. If you dig a bit you will probably find an USB C version.
