[ECOS] any tool/strategy present in eCos to load ram image stored in flash and run it ???

[Ram Sudhir Tadavarthi]

Hi all,

I am new to eCos. I have redboot working for my platform(PQ2FADS-ZU board).
Now I am creating ram images on the host and loading the ram images to the
target using the redboot load via tftp and running them successfully.

However in production series, we would like to store the ram image in flash,
copy the image in ram and run it from ram.

Is there any tool/strategy/option in eCos to do this? Can we configure
redboot to do it?

In my point of view, most of you might have done this already. Can anybody
give me hint how to do this.

Thank you,
ram

Yes, reboot will do this for you. Look at the FIS parts of the redboot
documentation.

This is exactly what the FIS (create/load) commands are for.  You can 
create a boot script to load the image and execute it.

To create the image:
  RedBoot> lo program_image
  RedBoot> fi create program

To run it in your boot script:
  (boot) fi lo program
  (boot) g
