I am sure you would have powered on the board. So that possibility is ruled out. What remains is the JTAG connection. Three possible causes of error are there:

1. You haven't downloaded the correct .sof file to the FPGA.

2. If you are configuring from a configuration device or flash, then the configuration device/flash don't have the correct image (.pof).

3. The cable that you use is not correctly configured.
