FPGA in-the-loop ERROR: "iMPACT:2204 - Can only assign file to device 1". How can I solve this error??

Hi all,

I have problem in loading .bit file to FPGA while veryfying FPGA in the loop using Matlab HDL Workflow Advisor or FIL verification Wizard. Iam using Spartan-6 XC6SLX45 board from Xilinx. The connection to the board is OK.

I encounter error at the end of loading process. "*ERROR:iMPACT:2204 - Can only assign file to device 1*" .The board is properly connected to the host computer with JTAG and Gigabit Ethernet Crossover Cable. I didn't find proper solution in other similar forums.

Please anybody can help me?
