[ECOS] Problem in installing redboot

[Suresh N]

Hi,
    while building redboot for mbx board i am getting error in this
command to get redboot.ppcbug

<cut>
powerpc-eabi-objcopy -O srec
/export/home1/nsuresh/ecos/redboot-build/install/bin/redboot.elf
/export/home1/nsuresh/ecos/redboot-build/install/bin/redboot.srec
powerpc-eabi-objcopy -O srec --change-address=0x02040000
/export/home1/nsuresh/ecos/redboot-build/install/bin/redboot.elf
/export/home1/nsuresh/ecos/redboot-build/install/bin/redboot.ppcbug

powerpc-eabi-objcopy: unrecognized option `--change-address=0x02040000'
</cut>
any idea why this change address is required ?

thanx in advance,
regards

What version of powerpc-eabi-objcopy (where'd you get it) is this?

The option is used to move the code [relocate] so that RedBoot can
be programmed into the Flash by EPPCbug.  The Flash chips actually
change addresses based on a jumper, so the device that RedBoot will
actually be in is at 0xFE000000, but EPPCbug sees it at 0xFC000000.
The "change-address" option takes the image destined to load at
0xFE000000 and move it so that it will load at 0x00040000.

If you found those tools, you would probably have seen they were for an old
version of eCos. You can get newer tools by downloading binutils 2.11. See
http://sources.redhat.com/ecos/tools/linux-powerpc-eabi.html for more.
