What I mean is that when I open up the Programmer window, I click the autodetect to detect my FPGA after I have selected the USB-BlasterII and I get the error message "Unable to scan device chain. On-board programming hardware is disabled". I am using the Stratix V GX FPGA Dev Kit. I have not probed the JTAG pins, I tried resetting all the DIP switches and pressing the different reset buttons but have not been able to fix anything. Thanks.
HI JWrig25,
Can you kindly try to reduce your TCK frequency to 6 MHz?
Below link is the command to change TCK frequency (on page 14= 2.8. Changing the TCK Frequency)

Kindly try it out with your design and let me know the result.
Thanks
