Updating EPCS with new configuration via FPGA

Hi all, Currently I am trying to develop a way of updating the EPCS memory connected to a stratix II device dynamically via the FPGA. The idea is that an external processor will send the configura...

I guess, this point is already handled by the ALTASMI_PARALLEL MegaFunction, because it has a byte interface.
