Wolfgang,
That was it. Thanks. I needed that sym link "ln -s . tftpboot" to get it to
work. Thanks a million.
Wolfgang Denk:
Might want to make a note to add that clip to section 3.2 "Configuration of
a TFTP Server" to the "PPCBoot and Embedded Linux Guide" as I don't recall
seeing it there.

Is the TFTP server started with the argument "-s"? Then do:
$ cd /tftpboot
$ ln -s . tftpboot
Hope it helps,
Wolfgang.
