Help request for FLASH remote programming

Hi,

Thanks for your letter. AN521 deals with putting 3 files into one POF file and burning them through a local JTAG. I need to write a user-logic that will reside inside my FPGA, and upon triggeriing from an outsdie controller card will receive the bytes of the a new configuration file, and I would like to write those bytes to a parallel CFI flash(remote update function). The external controller card receives the new configuration file via a TCP/ IP protocol from an extrnal site. My FPGA is a Cyclone III device and I work in an active parallel mode to program the CFI Flash device. Can I still use the altparallel_flash_loader megafunction? How? Can I just take the bytes I receive, one by one from the external controller card, and 'give' it to the altparallel_flash_loader megafunction that will write them to the parallel CFI flash? What will trigger the altparallel_flash_loader megafiunction to make this writing to the Flash?

I'd appreciate if you could guide me here, or even point me to a reference design that does a similar job.

Sincerely,

Eldad Fargon
