Static network interface

Question

When editing a file: /etc/network/interface

Something like this:

auto eth0
allow-hotplug eth0
iface eth0 inet static
address 192.168.0.1
netmask 255.255.255.0

and when I enter the command make, my interface bacome default. How can I set a static address interface eth0 in Buildroot?

The problem is that make overwrites your changes with the default. You need to enable Root Filesystem Overlay:

System Configuration -> Root Filesystem Overlay

Root Filesystem Overlay points to a folder in your host (/home/user/overlay, for instance). That folder can contain any files which will be copied to the target image before is built. Put your interface file in overlay/etc/network/interface and it will be copied to your target image.
