We use tcpdump to trace the packets as following: Is Uboot trying to do ftp now? We do have the tftp deamon running. Starngely, after these packets, tcpdump does not receive anything anymore?? ====================== [root@ohm2-cx etc]# tcpdump -i eth1 -s 200 -n -x tcpdump: listening on eth1 10:17:05.789993

We use tcpdump to trace the packets as following: Is Uboot trying to do ftp now? We do have the tftp deamon running. Starng ely, after these packets, tcpdump does not receive anything anymore??
Ummm... judging from the output U-Boot is sending a BOOTP broadcast. It did not receive a reply, so it is continuing to do so.

You don't really expect that I manually decode this hexdump? Sorry, I don't have that much time.
Please attach the data in a usable format (i. e. use "-w file").
Best regards,

Without looking up the bootp spec (again), I'd guess that the bootp server isn't responding. I believe that if the packet were ill formed, tcpdump would show something peculiar.
