Sure, just wire all the standard JTAG pins (TDI/TDO/TMS/TRST/TCLK and GND, maybe Vdd).I think tms does toggle, but I'll check tomorrow as it's late here in oz. I have a Xilinx (Digilent) JTAG, could that be made to work? Thanks for your help.You could try hooking up some other JTAG master, if you have one, perhaps.
Your JTAG software needs to be able to handle generic stuff though. Simply reading the
IDCODE after reset would be enough for the test; if that works, you know your target
chip isn't the culprit.
Of course the easier test would be if you just had an extra XTAG-2 or target board ;-)
