Hi All,
I'm seeing a strange TFTP issue and hoping someone on the list can help.
I'm running a Sequoia reference board and at start-up my TFTP transfer
always times out for 30 seconds, then proceeds without error or
further issue.
I ran Wireshark on my TFTP server, and also performed a port mirror of
the Sequoia board. I can confirm TFTP requests are only initiated 30
seconds after tftpboot is run.
Running with a static IP and the latest RC2 release of U-Boot. Boot
command is as follows:
net_nfs_fdt=tftp 200000 ${bootfile};tftp ${fdt_addr} ${fdt_file};run
nfsargs addip addtty;bootm 200000 - ${fdt_addr}
Startup log always looks the same...

I think this has always been happening, even with older versions of
U-Boot. I finally got annoyed enough with this problem to dig a little
further.
