Connecting Virtex- 5

I am using Xilinx 14.4. When I am trying to debug my project with SDK. 
The following error is thrown....

Unable to connect to microblaze

Could not detect MDM peripheral on Hardware. Please check

1. If FPGA is configured properly
2.MDM core is instantiated in the design.

My system.mhs file looks like this...


BEGIN microblaze
PARAMETER INSTANCE = microblaze_0
PARAMETER C_USE_BARREL = 1
PARAMETER C_DEBUG_ENABLED = 1
PARAMETER HW_VER = 8.40.b
PARAMETER C_FSL_LINKS = 1
BUS_INTERFACE DLMB = dlmb
BUS_INTERFACE ILMB = ilmb
BUS_INTERFACE DPLB = mb_plb
BUS_INTERFACE IPLB = mb_plb
BUS_INTERFACE SFSL0 = fsl_test_peripheral_1_to_microblaze_0
BUS_INTERFACE MFSL0 = microblaze_0_to_fsl_test_peripheral_1
BUS_INTERFACE DEBUG = mdm_0_MBDEBUG_0
PORT MB_RESET = mb_reset
END


Please help me in solving this...
