Uboot + Stratix EP1S40 + nios2

I am trying to download the u-boot.bin file that I created using debian linux with gnu cross-compiler for uclinux.

I am using nios-II command line utility program that comes with altera NIOS-II IDE ...which I downloaded from their website.

After running this command " bin2flash --input=u-boot.bin --output=u-boot.flash --base=0x00000000 --flash=U5 --location=0x0

I got a file "u-boot.flash"

when I was trying to run "nios2-flash-programmer --base=0x00000000 --input=u-boot.flash --sof=standard.sof --verbose

NOTE:---- The "standard.sof" file came with altera's software for "niosII_stratix_1s40" board.

I got an error....which is copied below:

In order to program flash, you must first create a purpose-built

flash-programming design (i.e. FPGA configuration) and associate it with

your particular board. The Nios development kit is delivered with purpose-bui
