Stratix V GX 100G Dev Kit JTAG Not Working

On the Stratix V GX 100G dev kit, when I try to keep the Max II in the chain (J62 unconnected) I get a JTAG error when autodetecting, and the JTAG debug tool says "UNKNOWN_DEVICE" where the Max II sh...

    Since none of the above helped, thought I would post the work around I used in case anyone else runs into this. Solution was to set JTAG clock to 6MHz, for some reason it was not detecting correctly at the default USB Blaster II speed of 24MHz. Still not clear why the onboard JTAG doesn't work.

Hi Mark, Can you please check if the JTAG driver is properly installed in your PC? Regards, YL

    Yes it is installed correctly, I have programmed multiple FPGA's before with the same setup and the Dev Kit works to program the Stratix FPGA directly if I use a jumper on J62 and remove the Max II from the JTAG chain. I get the exact same error for this board on multiple setups.

    Since programming FPGA directly works fine, using .jic file is the best option, but what are the settings for creating the .jic for this dev kit? I cannot find any mention of it in the user guide or dev kit reference documentation.
