The reason I need to load an ELF image is because we have both
internal RAM and external RAM in our system and we would like to place
code in the critical path in internal RAM for faster access and leave
the non-critical code in external RAM.
Because the two regions cannot be made contiguous, I cannot load it as
one binary image.
Thanks, David

Hi,
Thanks so much for all the help, I now have redboot running on my
custom board with flash support.
The next step, which is one of my main objective is to be able to load
an ELF image from flash to the corresponding RAM regions and have
redboot jump to the right entry point specified in the ELF header.
I tried a simple _fis create_ of the ELF image to flash, but when I
did _fis load_ all it did was load the ELF image as is to RAM _Mem
addr_. Is there currently a way to load an ELF image correctly?
Thanks, David
There currently isn't a way to do this directly using the FIS commands.
That said, the new 'load' command structure can easily be extended for
any media, so it wouldn't be too hard to extend RedBoot to be able to
do something like this:
RedBoot> lo -m flash image.elf
