I'm using a Spartan3 XC3S400 configured by an XC18V02 prom. The fpga will contain a edk microblaze core with "opb_jtag_uart" debug and external flash ram for code storage.
Q. Do I need a BSCAN_SPARTAN3 ?. I really cannot understand the documentation. If I do need one, how do I connect it up, because if I leave it unconnected as the docs suggest then I get ISE unconnected port errors for TDO1 and TDO2.
