    " TFTP from server 10.0.0.155; our IP address is 10.0.0.110<BR>     Filename '0A00006E.img'.<BR>     Load address: 0x30000000<BR>     Loading: T T T"
 
     The board can ping the pc.

1) Run ethereal and sniff the ethernet, see what the TFTP packets are
being transmitted.  Quite likely you will find you don't have a TFTP
server on 10.0.0.155.

2) Run TFTP on a different machine and see if you can get the file.
This will show if the TFTP server is operational.

Check if a firewall is runing on your Server!

try this manually:

tftpboot <address> <filename>

- address: somewhere on your RAM

Problem is in source code net\tftp.c. 

MAC address is set to zero. 
Set MAC address to broadcast. (all 0xf)

Old
memset(NetServerEther, 0, 6); - zero MAC

New
memset(NetServerEther, 0xff, 6); broadcast MAC

You are trying to download the file 0A00006E.img from the server. Is
this file present on the server?

This file name is made from your MAC address apparently. I think you
forgot to specify file name in your tftp command line unless you really
want to download the made up filename according to your MAC address.

Please provide the command you have typed if you are looking for more
specific help next time.

Best regards,
Tolunay

No, not from the MAC address, but from the IP address.
