Problem is still same. You must change one parameter in  /net/tftp.c 
Broadcast is defined with MAC address ff:ff:ff:ff:ff:ff, but now is defined as 00:00:00:00:00:00.
Change one line (at the end of file).
old:	memset(NetServerEther, 0x0, 6); 
new:	memset(NetServerEther, 0xff, 6); 

And send me echo.

You really should fix your mailer.

You claimed this before. Can you  pelase  point  out  which  official
standard  says  that  00:00:00:00:00:00  should  be used as broadcast
ethernet address? All information  available  to  me  says  that  the
boradcast MAC address is all bit ones; see for example
http://en.wikipedia.org/wiki/MAC_address :

        The broadcast address, all one bits, is received by all
        stations on a local area network. In hexadecimal this would
        be "FF:FF:FF:FF:FF:FF".

You are using default environment. I doubt you have a default MAC
address in default environment. You must setup your board specific MAC
address in environment for network to work on most boards.

Check your MAC address. You might want to sniff some network traffic to
see if your board is using correct MAC address as well.
