Hi there,

use nio2-elf-objcopy

you will probably want something like:

nios2-elf-objcopy -O binary input_file.elf output_file.bin

hello cybdenw

I used

nios2-elf-objcopy -O binary input_file.elf output_file.bin

the input file .elf :409KB but the output_file.bin is 9M

it seems wrong

i use the following script, it converts first

from .elf -> .flash and then from .flash(srec) -> .bin

you have to adjust some settings in the script (addresses)

SCRIPT: elf2bin.sh

use: elf2bin <ELFFILE> <BINFILE>
