[U-Boot-Users] Network problem in u-boot.
Hi all!
I make a new post on the same problem since I found out some new info.
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.

Please read the netiquette. It would have been muchbetter to post a follow-up so the complete thread of this discussion would have been visible.

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?
Best regards,

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.
