Hi
I have built a parallel cable III and uses only resistors for protecting my lpt port.it can config my spartan II (xc2s200) device.now i have made a new board with XCF04S and xc3s400 device in jtag chain. when i start iMPACT it recognizes these devices but when i try to read devices id or doing something else it say's read faild and similar messages.does any body know how to solve the problem.
thanks in advance.
