Programing CFI Flash

Hello, I want to run a NIOs processor on a Cyclone III with code stored in a CFI flash. The FPGA is programed via an EPCS controller. How do i program the code on to the CFI flash? Do i ne...

The MAX device on the dev. boards is to provide a method for programming the FPGA using data stored in the CFI compatible flash. As far as your FPGA code is concerned, it's not even there. The CPLD should relinquish control of the flash data bus once programming of the FPGA is complete.

In your SOPC system, all you need is an Avalon Memory-Mapped Tri-state bridge and a CFI flash controller.
