ADSP-SC589 EZ-Board Linux networking

I have now successfully installed the linux image on a SDcard on my ADSP-SC589 EZ-Board it is booting.

However, there is no DHCP networking enabled on this linux image, so I have to use the minicom.

Are there any instructions on how to set up DHCP on the ARM linux core?

The info found on google does not always apply, since this pre-configured image does not contain all networking tools.

i tried /etc/network/interfaces:

# interface file auto-generated by buildroot
auto eth0
iface eth0 inet dhcp
auto lo
iface lo inet loopback

but it had no effect.
