Have you included sys/alt_flash.h and sys/alt_flash_dev.h?? I have also implemented the driver over the NIOS2 IDE, but I have also to implement the two above to get it working. Code looks like this:

...# include "sys/alt_flash.h"# include "sys/alt_flash_dev.h"

...

alt_flash_fd* any_epcs;

char data_array_name[16];

int ret_code = 0;

...

my_epcs = alt_flash_open_dev(EPCS_FLASH_CONTROLLER_0_NAME);

ret_code = alt_read_flash(any_epcs, 0, data_array_name, 16);

...

good luck!
