I thinks that's a connection refused error. Is the FTP host all set up
on your PC side? It looks like your taget and host are on the same
network - right? Does the board ping OK when you boot from flash?

If you want to debug, I'd put ethereal on the net and see what's goign
wrong with the download - you should see an FTP login to your host with
that user/pass that you've got set in your boot prarams.
