JTAG prgramming is not working in my Cyclone 4 based board.

Hi all,
I'm new to this forum. I have one issue in my Cyclone 4 (EP4CE6E22C8N) based development board..
Please provide some basic tips.

FYI: TDI, TMS pins of the JTAG connector always LOW (even I have pulled up by 10K resistor), I belive, it should not be LOW..


Please share your solution .

Thanks in advance..
