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´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

eCos is one alternative. It was designed to be a real-time embedded

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.

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 ...

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

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

Hello Sandra,

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

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.

hi everyone,

at first, thanks for responding, that´s 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´t
need vga, it´s just for testing).

greetings,
sandra
