Since the ID code is all zeroes, it looks like your scan chain is broken. Check that the part has all of the
required power supplies. A missing core logic supply or VccAux could cause this. Also make sure all of your
JTAG signals are connected correctly. Missing connections to TDI, TMS or TCK can also cause this sort
