[ECOS] redboot functionality from user application

[ECOS] redboot functionality from user application

[Saurabh prakash]

hi ,

i am a newbee, i have ported redboot to my custom
powerpc
board. i have used mbx template. i get redboot prompt
and
i can use commands like fis, fconfig, mfill, dump..
etc.
   my problem is that i want redboot functionality
from my user
application.i don't want a seperate redboot image. i
have gone thru' anthony's book and he has mentioned
somewhere that the final product should (ideally)have
the rom-ram startup type and 
gives a diagnostic console terminal(like redboot)
where we can 
give commands? IS THIS POSSIBLE. if yes how?

thnx in advance

eCos does not provide such an environment as a standard
component.  However, it's simple enough to write such
a command line (UI) if you wish.

In general though, eCos applications are all about solving
a particular problem in the embedded environment.  This
seldom involves interactive command line processing such
as what you mention.

What's your application doing that it still needs such
functions?  or, alternatively, what is missing from just
the RedBoot environment for what you need (if you truly
need all these trappings)?

Appreciated, thanks.

While RedBoot is quite complete in itself, if you want to 
provide similar functionality in your application, I think
you'd be better off writing your own framework, possibly borrowing
ideas, etc, from RedBoot.  The RedBoot code itself was not really
designed for sharing or re-use.

It may make sense for you to provide such functions in your application,
if you have the resources (memory, CPU cycles, etc).  That's a decision
you'll need to make yourself.

reminder: please copy your replies to the eCos mailing list so that all
may benefit from the discussion.  Private support is available from
various parties (including myself) under contract.  If you need detailed
support, that may be the best way forward, but unsolicited private email
is discouraged.
