[ECOS] newbie

[Lance Uyehara]

Hello,

I'm in the evaluation stage of a project, and we're looking at ecos as a
potential kernel solution. I'm currently looking at the ecos configuration
tool and wondering if people are using this.

It seems to me like specifying arm pid or arm aeb (for example) is far too
restricting. Wouldn't we want something more like arm720T or arm7TDMI?
Because any project I develop won't be targeted to run on any development
board, but rather would be targeted to run on our actual product board.

So I guess my main question is are people using the configuration tool, or
using the repository with hand built makefiles, or is it some combination
of the two?

Thanks,

Oh, absolutely :-).

Currently via anonymous CVS, for ARM we support AEB, PID, Cirrus Logic
CL7111/EDB7211 and Cogent CMA230 boards. One of those might be closer to
your product board. We have other non-public ARM ports as well but you can
only get those with our "early access" program.

It sounds like you need to do a port of a "platform HAL" to your board. It's
probably best to copy one of the existing platform HALs that is closest to
your product board, and start making appropriate changes :-). The way eCos
is architected, it takes surprisingly little time to get a basic port doing
something (there's a lot of stuff you can skip over that isn't needed to get
simple programs running at first).

Comprehensive testing can be tricky though - here at Cygnus we have lots of
automated testing for lots of our customers' board ports that tends to show
up lots of timing problems etc. that would be difficult to find otherwise.
It's something to remember anyway - just because it *appears* to work
doesn't mean it always does, so you should be prepared to do lots of very
repetitive testing if you want a solid port.

I'm sure people on this list would be happy to help answer questions you
have doing the port. Although, of course, Cygnites can't guarantee to answer
questions in great detail nor very quickly because we have to serve our real
support customers first... but we try and help at some level when we have
time.

It is ported on the ARM7tdmi which is there in the ARM Evaluator board.

Hi List ,  I am a newbie to this list.I wnated to know
1)Is the ecos supported on ARM7tdmi (without mmu) (I just read on the web
page that it supports arm7tdmi but just wanted to make sure it works on a
non mmu machine )
2)Has anyone ported the Ecos to Samsung S3C44BOX ?  (The archive search
could not get me any valid result !!)

Thanx in advance for your reply.
