Implementing Microblaze on spartan 2, Error: Memory of data width 32-bit and memory size 8-kBytes does not fit in a fixed

I'm implementing a Microblaze on a spartan 2 XC2S200 fg456 device and this error comes up:-

 

ERROR:MDT - lmb_bram_if_cntlr (ilmb_cntlr) - J:\Hello\system.mhs line 97 -
   Memory of data width 32-bit and memory size 8-kBytes does not fit in a fixed
   size.
   Only the following memory configurations are supported:
   -----------------------------------------------------------------
                    |    Memory (kBytes)   |    Memory (kBytes)    
      Architecture  |      32-bit data     |      64-bit data      
                    |      byte-write      |      byte-write

   Spartan-IIE      |       2 4 8 16       |        4 8 16 32      

.....................................................................................

Where in the BSB the minimum BRAM size given was 8KB !!!

 

However I've modified the MHS file to make both dlmb_cntlr and ilmb_cntlr adresses 4KB only and this error vanished but still the design is not functioning even the basic testApp_Memory is not functioning, Any suggestions its urgent please.

 

Thanks,
