Troubleshooting • Re: Headless, RPi Zero 2 W, configuration & connection guide

The trick isn't enabling the serial gadget it's enabling a login on it when you have no other way in to the Pi.

This should work but is untested:

1. Make sure you have the following in your config.txt:

   Code:

   [all]dtoverlay=dwc2

2. Remove any existing modules-load=dwc2,g_ether or similar from your cmdline.txt
3. Add the following to the end of your cmdlinr.txt:

   Code:

   moduels-load=dwc2,g_serial console=ttyGS0,115200

4. (Re)boot

You won't get kernel boot messages on ttyGS0 (it starts too late for that) but you should be able to login without manually enabling a getty on it.

And you do not need any sort of specisl cable for this. A normal USB A male (host end) to micro B male (zero end) charge and sync cable is fine.
