how does the cyclone dev board boot from flash?

I'm look at board level implementation of a Cyclone design right now and want to load my .sof and program from a CFI flash. According to the handbook it looks like i need a micro of sorts (the m...

The MAX controller is used to clock FPGA configuration data into the cyclone device from CFI (AMD) flash on the board; Cyclone cannot configure itself from CFI flash alone.[/b]

Thanx Jesse. So, should I conclude following from ur observations?

(1) MAX controller not required if EPCS device is used for configuring the FPGA. If EPCS is not used MAX controller is required to load FPGA with the configuration data. This data is stored in Flash Memory in this case.

(2) In either of the cases, NIOS II software doesn&#39;t require MAX controller per se for either booting or executing from flash.
