Write/Read EPCS4 with NIOSII

I'm a newbie. I want to read and write on my EPCS4 connected directly to a Cyclone3.

I included in my SOPC Builder:

- CPU

- On chip memory (RAM)

- EPCS serial flash controller

The first problem I encountered is:

Pin dclk -> DCLK

Pin sce -> FLASH_nCE

Pin sdo -> DATA1_ASDO

Pin data0 -> DATA0

ok

but the pin MISO ->????? how I connect the FPGA pin?

I do not connect it.

I will try to write and read a bit on the EPCS, I read a lot of discussions but I could not get my software.

I followed those who should be included and defined as follows:

# include "system.h"# include "sys / alt_flash.h"# include "altera_avalon_epcs_flash_controller.h"# define ALT_USE_EPCS_FLASH

Could you be so kind as to suggest a simple listing that will enable me to write and read a bit on EPCS. Then I hope to be able to continue alone.
