Hey guys
I have used XC6SLX9-3TQG144I in my design. according to data sheet the jtag circuit must be like the illustrated image. I have implemented it in my board.
my problem is that when fpga is not programmed (after connecting power supply) I can program my board successfully. done pin goes high. but after that I can not connect to board with jtag interface. I can not use chipscope. I also can not reprogram it again. could you please tell me what i should do?
thanks a lot.
