does anyone know an embedded system, that already includes a RT S?

eCos is one alternative. It was designed to be a real-time embedded
operating system. It's also open source.

Hi folks,
I need some advice:
For my diploma thesis, I need an embedded PC with CAN, RS232, Ethernet,
RT S and low power consumption (for use with battery).
Finally, I found a system, that would fit best, but the problem is,
that it just includes standard linux support. (its an embedded pc
system from janz, with NS Geode GX1, 300MHz,
)

Careful! The Geode is not exactly an ideal processor for real-time use.

(see for example: )

And have got really no experience with RTAI or RTLinux(and just a few
experience with Linux itself). Does anybody know, how much work it
would take to extend the system?

Last time I looked, you had to get the kernel source, apply a patch,
configure & build your own kernel. Piece of cake if you are used to
patching and building Linux kernels but can be a nightmare if this
is all new to you.

And what would be better, RTAI or
RTLinux?

I'd personally prefer RTAI because I think the poeple on the RTAI
mailing list tend to be more helpful, and because I don't like the
RTLinux patent. But that's just my personal taste

does anyone know an embedded system, that already includes a RT S?

<shameless plug>
My company sells an embedded Linux tool suite which comes with RTAI
preconfigured, plus some samples (see my .sig).

And many more here:

Perhaps eCos will run on it -- it runs on other PC-compatible
motherboards.

RTAI is free.

Sorry.

I have no idea why my reader ( Express) didn't do this automagically.

I have it set up to do so, and I see that it did prefix quoted lines in this
reply.
