nios2 .flash files are srec files
1.
a) use elf2flash to generate flash-file from elf-file
http://forum.niosforum.com/work2/style_emoticons/<#emo_dir#>/cool.gif use nios2-elf-objcopy to change address of srec file
2.
a) use elf2flash to generate flash-file from elf-file
http://forum.niosforum.com/work2/style_emoticons/<#emo_dir#>/cool.gif use nios2-elf-objcopy to generate binary file from flash-file
c) use bin2flash to generate again flash-file at new offset
sample script for 1.
srcname=hello_world_0
flash_offset=0x100000 # where program is stored in flash
src_file=./src/$srcname.elf
dst_file=./flash_files/$srcname.flash
dst_file_off="./flash_files/"$srcname"_"$flash_offset".flash"
echo ----------------------------------------------------------------------------
echo "start elf2flash"
