Quick nios2-flash-programmer question

two possibilities done with script files (not from ide)

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.

FLASH_OFFSET=0x100000 # where program is stored in flash

SRC_FILE=./src/$SRCNAME.elf
