The FPGA isn't involved in AS programming, the FPGA AS interface is disabled by the USB Blaster or another programmer, as it pulls up the nCE line. AS Programming would be possible without a FPGA assembled to circuit.
But the FPGA can also program AS memory through the interface, this is utilized with said serial flash loader.

OK, a step in the right direction thanks to this info. I pulled all of the jumpers connecting the EPCS to the FPGA circuit and now the EPCS programs and verifies properly. So I think I will move forward by replacing the previous 0Ohm jumpers with small resistors and see what I find.
Just wanted to give the latest update in case it inspires any ideas on someone else's part.
Appreciate your time and help.
