Quick nios2-flash-programmer question

Hi.

Does anyone know if its possible to program multiple software (elf / flash) applications into a single flash device, where each program is located at a different address? If so, how may this be done?

I saw another thread asking this very question, but the answer was to use the --offset tag with elf2flash, however, this tag does not seem to be supported anymore (was it ever?).

Thanks a bunch,

Kevin

(P.S. Does anyone else have issues with the 'search' tool on this forum? It never returns decent results)

    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.

    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"

    FLASHBASE=0x000000 # BASEADDRESS OF FLASH

    FLASHEND=0x7FFFFF

    RESETADDRESS=0x000000

    FLASH_ID=U1

    BOOTLOADER=boot_loader_cfi.srec # BOOTLOADER

    echo "ELF FILE : "$SRC_FILE

    echo "FLASH FILE : "$DST_FILE

    echo "BOOTLOADER : "$BOOTLOADER

    echo "FLASH ID : "$FLASH_ID

    echo "FLASH BASE ADD : "$FLASHBASE

    echo "FLASH END ADD : "$FLASHEND

    echo "RESET ADD : "$RESETADDRESS

    elf2flash --input=$SRC_FILE --output=$DST_FILE --base=$FLASHBASE --end=$FLASHEND --boot=$BOOTLOADER --reset=$RESETADDRESS --flash=$FLASH_ID --verbose

    echo ----------------------------------------------------------------------------

    echo "START objcopy"

    echo "INPUT FLASH FILE : "$DST_FILE

    echo "OUTPUT FLASH FILE : "$DST_FILE_OFF

    echo "OFFSET IN FLASH : "$FLASH_OFFSET

    nios2-elf-objcopy -v -I srec -O srec --srec-forceS3 --srec-len 32 --change-addresses $FLASH_OFFSET $DST_FILE $DST_FILE_OFF

    echo ----------------------------------------------------------------------------

    echo "START quartus_programmer"

    BOARD_CONF_FILE=b12dal03_fpga.sof # PATH TO FLASH PROGRAMMER BOARD FILE

    JTAG_DEVICE=2 # NO OF DEVICE in JTAG_CHAIN

    echo "BOARD_CONF_FILE: "$BOARD_CONF_FILE

    echo "JTAG-DEVICE : "$JTAG_DEVICE

    quartus_pgm --cable="USB-Blaster [USB-0]" --mode=JTAG --operation="p;$BOARD_CONF_FILE@$JTAG_DEVICE"

    echo ----------------------------------------------------------------------------

    FLASH_FILE=$DST_FILE_OFF

    BASEFLASH=0x00000000 # BASEADDRESS OF FLASH

    echo "START nios2-flash-programmer"

    echo "FLASH FILE : "$FLASH_FILE

    echo "JTAG-DEVICE : "$JTAG_DEVICE

    echo "FLASH BASE ADD : "$BASEFLASH

    nios2-flash-programmer --debug --device=$JTAG_DEVICE --accept-bad-sysid --base=$BASEFLASH $FLASH_FILE

    Wowha! How did I miss all of those GNU tools?! Bonus! Thanks a bunch,
