hi everyone,

at first, thanks for responding, that=B4s really helpful.

@rob: what do you exactly mean with "The Geode is not exactly an ideal
processor for real-time use"?
Is that restricted to any specific devices (in the given link, the
problem occured with the graphical output. in my application, we don=B4t
need vga, it=B4s just for testing).=20

greetings,
sandra

Sorry.

I have no idea why my reader (Outlook 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.

For the RTOS part .. you have simply to talk to QNX Germany in Hannover.
QNX Momentics (the development system) is free for universities after
signing some agreements.

We can also deliver different CAN controller boards (PC/104, IS, PCI)
inclusive QNX6.3 support.

Good low power embedded CPUs are e.g. these PC/104 CPU boards

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

Hi folks,

I need some advice:

For my diploma thesis, I need an embedded PC with CAN, RS232, Ethernet,
RT OS 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. (it&#4294967295;s an embedded pc
system from janz, with NS Geode GX1, 300MHz,
http://www.janz.de/as/files/empcx302.pdf )
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? And what would be better, RTAI or
RTLinux?

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

Thanks a lot,
Sandra


I know that one signficant difference between RTLinux and RTAI is $$$.
RTAI is free.

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

(see for example: https://mail.rtai.org/pipermail/rtai/2004-March/006661.html)

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

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 ...

> Or does anyone know an embedded system, that already includes a RT OS?

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

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:
