Hi All,
             The issue has been resolved.
              I built the u-boot-nand.bin image from the u-boot cource code 
obtained from the AMCC site.
              With this image tftp is working fine,once i set the 
ethaddr,serverip and ipaddr.
              Initially i was working with the latest u-boot source code from 
the denx site.I found out that there was some differences between these two 
versions.For example the lates u-boot source code does not contain the file 
/drivers/net/4xx_enet.c while the one from AMCC site contains the same.
             Thanks.

Regards,
Afzal Nadirshah

Your board doesn't have a correct ethernet link. Is this really the original
Canyonlands board? Is the correct ethernet port connected?

Best regards,
