Hello,
I'm trying to port the last release of barebox to my sbc2440-III board with the base config. of a mini2440 but unfortunately I'm facing a network issue when trying to boot from nfs or to load files with tftp.
After checking all the parameters (pll, ram init etc.) I figured out that the chip select and interrupt pinout were not good and I changed them to fit with my board schematic.
So I have a well boot on barebox everything seems to work as you can see here :
barebox 2012.03.0-00113-g881d9e9-dirty (Mar 23 2012 - 00:45:52)
Board: Mini 2440

running /env/bin/init...
But, when I try to ping or boot from nfs/tftp, the phy isn't receiving any packet from host :
Hit any key to stop autoboot: 0
warning: No MAC address set. Using random address F6:48:4B:C2:51:44
phy0: Link is up - 100/Full

I'm sure the host is well configured because I usually have to work with other boards using nfs and tftp.
Here is more complete log of the packets transaction I hope it could help :
