Hi, 

 

Are you using the USB blaster J12 plug (the one next to the 2x10 pin header (J20)? This is the USB blaster port and not the next one. Make sure the USB cable is plugged into this one. This J12 port is the embedded USB blaster port. Use the HArdware setup option to check if the programmer can detect the board and cable. If successful, you should see the device in the JTAG chain. You can select it and change the file to be programmed.
