Hi Raja,
    Did you update the xparameters_ml300.h or xparameters_ml403.h file 
with the right defines for your specific board? If not, then you need to 
update the file first. This first is automatically generated by the EDK 
toolset. However, you might also choose to do it manually if you know 
the right values. The driver would work with the right base-address.

cheers,
-Ameet
