hi,

use the nios II command shell and sof2flash/elf2flash/nios2-elf-objcopy programs. options depend on your needs.

# 1) Convert SOF to Flash

sof2flash --input=filename.sof --output=hwimage.flash --epcs --verbose# 2) Convert ELF to Flash

elf2flash --input=../filename.elf --output=swimage.flash --epcs --after=hwimage.flash --verbose# 3) Concatenate

cp hwimage.flash hw_sw.flash

cat swimage.flash >> hw_sw.flash

# 4) Create HexFile

nios2-elf-objcopy -I srec -O ihex hw_sw.flash hw_sw.hex

i use it in a tcl script and run it with nios II shell.
