How do I connect an Xchecker cable to an XS40 Board?
Q:
We are trying to download a design using the XChecker Cable. It doesn't seem to work properly. The Xchecker cable is the only way to activate the Hardware Debugger Tool in Foundation. Could you please supply an answer to this matter?
A:
The XS Boards don't have an interface that is compatible with the XChecker cable. You will have to build an interface by connecting the flying leads of the Xchecker cable to the pins on the underside of the XS Board. The connections are as follows:
Xchecker XS40 Lead Pin ==================== VCC 2 CCLK 73 DONE 53 DIN 71 PROGRAM 55 INIT 41 RST 8 RT 32 RD 30 TRIG 7 CLKI 13 CLKO 9 TDI 15 TCK 16 TMS 17 GND 52
You also have to disconnect the parallel port download cable from the XS40 Board and remove the shunts from the following jumpers:
