SPI Flash devices

i'm trying to use the AT25FS010 ATMEL SPI FLASH so i insert the file

nios2-flash-override.txt

and within there is:

[EPCS-1F6601]# EPCS1N (ATMEL SPI FLASH) S25FL064A0LMFI001

sector_size = 4096

sector_count = 32

but the result is:

[NiosII EDS]$ nios2-flash-programmer --epcs --base=0x00002000 "spi_flash.flash" --verbose

Reading override file "c:/altera/90/nios2eds/bin/nios2-flash-override.txt"
