nios2-flash-programmer user Guide

the right format of programming a bin to the flash like this:

step1:(transfer .bin to .flash)

$bin2flash --flash=U5 --location=0x0 --input=XXX.bin --output=XXX.flash

(the --location=0x0 means the offset of ur flashchip to write.)

step2:

$nios2-flash-programmer --input=XXX.flash --sof=../rca_cy1c12_board.sof --base=0x00200000

(the --base means ur flash chip physical address in sopc of ur ../rca_cy1c12_board.sof flash programmer project,don't confuse it with --location.

--flash=U5 means ur flash chip name in sopcbuilder

)

hope it helpful
