TS-4900 Network configuration example
Our Yocto image uses systemd which stores its network files in
/etc/systemd/network/. Yocto will automatically enable DHCP on its wired interfaces. This can be overridden to set a static IP or enable other options for DHCP. The only requirement is that this file is named
/etc/systemd/network/XX-wired.network Where "XX" is a number smaller than 80, e.g.
/etc/systemd/network/79-wired.network This format must be used for all
en* named network interfaces. The lower file names will take priority.
An example of a static configuration would be:
[Match] Name=eth0 [Network] Address=192.168.0.50/24 Gateway=192.168.0.1 DNS=192.168.0.1
DNS will be loaded from /etc/resolv.conf. To make this use a static DNS:
rm /etc/resolv.conf echo "nameserver 18.104.22.168" > /etc/resolv.conf echo "nameserver 22.214.171.124" >> /etc/resolv.conf
To use the DNS assigned by DHCP, run:
ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf
For more information on what options are available to configure the network, see the systemd network documentation.
