[Buildroot] Issues with network interface eth0

Wed Feb 17 16:06:05 UTC 2010

Hi All,

I’m using an ATMEL SAM9263-ek ARM9 and have successfully build everything
with the 2009.11 build.

I am however experiencing problems with setting up the eth0 interface.

I wanted to set the interface address via dhcp so i set the
/etc/network/interfaces file to

#-------------------------------------------

# Configure Loopback

auto lo

iface lo inet loopback

auto eth0

iface eth0 inet dhcp

#-------------------------------------------

This did nothing and i still had to set the address manually. So i tried to
set is manually at startup with

#--------------------------------------------

# Configure Loopback

auto lo

iface lo inet loopback

auto eth0

iface eth0 inet static

address 192.168.11.3

netmask 255.255.255.0

network 192.168.11.0

broadcast 192.168.11.255

gateway 192.168.11.1

#--------------------------------------------

Again no joy. However if i use dhclient i get an address via dhcp.

A liitle lost right now, am i missing something in the build or is it my
config?
