Hello,That guide is very light on details (for instance why are they setting up two ethernet interfaces? Why are they talking about bridging them?) and mistaken in at least one place.
Running rpi-update is also not generally recommended.
You can do it withourt running dnsmasq but Network Manager doesn't play well with the ethernet gadget so you have some different hoops to jump through.
Here's the minimum you need to do:
- See and apply Bookworm Point to Point Ethernet (inc g_ether).
Code:
sudo apt update && sudo apt upgrade -y- Add the following to your config.txt
Code:
dtoverlay=dwc2,dr_mode=peripheral- Add the following to the end of your cmdlline.txt making sure everything remains on one line
Code:
modules-load=dwc2,g_ether- Reboot
I'll leave configuring things on the USB host as an exercise for the reader.
You might want to take a look at USB Ethernet Gadget A Beginner's Guide but bear in mind that the networking sections have not yet been updated for Bookworm/Network Manager.
Oh, and unless you're running with no additional devices connected and with a light CPU/system load expect power issues - most USB port can't supply the current needed.
I actually posted a comment on that blog but it isn't approved yet, I found this thread in the meantime and thought to post here as well.
Can't seem to get that guide to work to create additional ethernet interfaces.
This is what I've done:
