When programming an XC18V04 I get a red "Programming Failed" indicator at
the end of the process. The device is connected to an XC2V1000 in SelectMAP
mode. I tried disabling "FPGA Load" but nothing changed. I should mention
that the boards come-up just fine, in other words, it seems that the
programming of the PROM is successful every single time, despite the
message.

The log file doesn't have any useful information. Can anyone suggest where
I might look to figure this out?

Thanks,

Is your JTAG chain including both SPROM and FPGA, or just your SPROM?

You might have a problem in your jtag chain. If your tdo does not
propagate through the XC2V1000 or to the final tdo pin (connected to
your programmer), your sprom could be programmed but the output check
fails.

I can program the FPGA (in the same chain) without any problems whatsoever.

That would rule out the mentioned potential problem.
