TFTP not able to find file???

[brian.auld at adic.com]

All y'all must've been wondering why I hadn't posted with a problem yet
today. Surprise!!

Checklist for my embedded 'linux on ebony/440GP' project:
---------------------------------------------------------
- cross tools working (check)
- bootloader built (check)
- bootloader installed in flash (check!!)
- bootloader runs (check!!)
- ... next load linux

Well, I've progressed to the point where u-boot is installed on the ebony
and running. I'm now trying to load linux and run, but I'm getting stumped
where tftp is not able to find the file I'm trying to load. The following
are attached below to show my settings:

(a) dhcp conf file on host
(b) listing of tftp directory
(c) ebony serial port log

Please note the following:
- Host/DHCP server ip=172.16.77.151
- Target ip=172.16.77.152 (assigned by dhcp server)
- Permissions in tftpboot directory are more than adequate
- I used DHCP because as I fuddled around with u-boot, it didn't see
  possible to separate tftp from bootp. In other words, even if I set
  ip addr(s) and stuff through the u-boot setenv command, the values
  would be automatically overidden when I run the bootp command. The
  BOOTP command seems to be the only way to kick off tftp, so I really
  wasn't able to find a way to make use of statically set network
  Config info.
- vmlinux.PPCBOOT is the product of my 'make uImage' build in my kernel
  source tree.

Any ideas on why this isn't working??
