Hi,
Was wondering if anyone has used the XCFxxP devices with revision selection controlled via the internal REVSEL bits rather than the external REVSEL pins?
I'm assuming the REVSEL bits are, once programmed, persistent (non-volatile), yes? Is it possible to re-write the REVSEL bits without having to download a new bitstream as well?
Finally, can anyone see a problem with the FPGA bit-bashing the JTAG on the PROMs to re-program both bitstreams and REVSEL bit settings? And what about the FPGA sending the CONFIG command to the PROM to initiate a re-configuration of itself?
TIA Regards,
