Embedded PC and RT

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=B4s an embedded pc system from janz, with NS Geode GX1, 300MHz,

) 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 operating system. It's also open source.

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

(see for example:

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 ...

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.

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

Please learn to quote other people. It is very confusing if you don't prefix quoted lines with ">".

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

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.

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
