Hi! Yes the mac is valid. I use 100Mbps FD and bootp to get an adress. U-boot gets IP 172.18.22.66 and netmask is 255.255.255.0

I´ll try to enable debugging later and post the results.

The problem is that sometimes the network in u-boot stops, e.g. just getting TTT in a tftp transfer. I foud out that this occurs when another packet not involed in the tftp fransfer arrives. It could be a TCP-connect attempt from another host to u-boot or a ARP request. With a network sniffer I can se that u-boot still send data, but all data ariving is never processed. A reset of the board is needed to get it up and running again.

The board is a custom bord whith AMCC440ep based on bamboo.

I cannot confirm this. I just tested approx. 20 downloads on a bamboo board without any such problems.

What exactly is your network configuration? 10 / 100 Mbps? FD / HD? IP addresses? Netmask?

And do you use a valid MAC address? Did you try to enable debugging in the 4xx ethernet driver? If not, please do this and post some results here.
