Re: How to configure eth0 on fslc-image-network-full-cmdline

If your image uses systemd-networkd, then the interface configuration files are in /etc/systemd/network.  For eth0 using DNS you should have a file eth0.network:

[Match]
Name=eth0

[Network]
DHCP=ipv4

I've got ethernet wired to a switch on my home network, but I cannot figure out how to setup this build to bring up eth0 via DHCP. Any help would be appreciated. Is this image supposed to bring up eth0 right out of the box?

There is a recent fix in 5.15.13 for Ethernet on wandboard

After applying this fix, I can confirm Ethernet is functional.

To get an IP address via DHCP:
udhcpc -i eth0
