Uboot version ?
Platform/Processor ?

Do u see any Uboot Init or startup messages.
Using Jtag you can debug and check where the Processor Hangs. 
May be the sdram location where uboot is about to relocate is not
accessible.

Hi Aruna,

This is a FAQ.
   <http://www.denx.de/wiki/view/DULG/UBootCrashAfterRelocation>

Just because your SDRAM configuration passes the ddr test doesn't 
necessarily mean it is working 100% correctly.  Misconfigured SDRAM will 
"work" if it isn't driven hard (i.e. pipelining effectively not being used).
   <http://www.denx.de/wiki/DULG/SDRAM>

If your SDRAM *is* working as you claim, you found a new problem and 
will have to update the FAQ.  :-/
