The CPLD on the board

When i connect the download cable to the isp of the cpld .In the iMPACT environment,there is an error when I want to initialize the chain.the error is as follow. ERROR:IMPACT:585 - A problem may exist in the hardware configuration.Check that the cable,scan chain,and power connections are intact,that the specified scan chain configuration matches the actual hardware,and that the power supply is adequate and delivering the correct voltage.

The CPLD itself is blank and doesn’t have anything it. Please find enclosed the schematic for the NS7520 board’s CPLD as it now exist. It will be improved going forward. Check the error with Xlinx support.
