RE: [ECOS] ethernet download

That sounds cool.  I never thought of that.  I'll try it.  How much RAM
does Redboot take up?  Can you have it take up a smaller amount of RAM
after it's started the other system?  We are only putting 1M RAM on our
target board so I can't have it taking up much.

That's true - for the primary ROM image.  If you're looking for a faster
way to load big ROM images, rather than keeping RedBoot in place, you're
out of luck I'm sorry.

What is it that you want to have in ROM?  Will it fit alongside of
RedBoot?
If so, you can keep RedBoot in there to help you download and manipulate
the FLASH (I hope it's FLASH!).  You can still execute from FLASH if you
wish, or use RedBoot commands to load & go from FLASH.

We do this sort of thing all the time with embedded Linux systems.
RedBoot
is kept for the purpose of system startup, download and FLASH
management.
When the system starts, a RedBoot script is used to startup the Linux
kernel, etc.
