I think there may be a little confusion here. Is your EPCS connected to the FPGA you want to use it on?

When you use the EPCS controller in the SOPC system it uses a small amount of On Chip Mem to act as a bootloader, which contains the code to fetch the program code out of the EPCS controller and load it into program memory.

The EPCS device is never on-chip memory, rather an external flash memory IC.
