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, 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

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 ...> 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). </shameless plug> HTH Rob -- Robert Kaiser email: rkaiser AT sysgo DOT com SYSGO AG http://www.elinos.com Klein-Winternheim / Germany http://www.sysgo.com

Thanks a lot, Sandra I know that one signficant difference between RTLinux and RTAI is $$$. RTAI is free. Steve

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 http://www.ampltd.com/prod/t886.html or http://www.technoland.com/tl_pc104_cputm5800.htm --Armin http://www.steinhoff-automation.com

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
