Please check the wiki,

http://nioswiki.jot.com/wikihome/operating...flashprogrammer (http://nioswiki.jot.com/wikihome/operatingsystems/%c2%b5clinux/flashprogrammer)

0. base address and size of your flash, epcs ?

1. how do you config fpga? from epcs or from cfi flash?

2. where the nios2 boot? from epcs or cfi flash ?

If you have epcs, you should use epcs to config fpga.

If your epcs is big, you can store zImage in epcs.

you can setup mtd partitions for epcs and flash.

so that you may update your fpga, and linux.
