First of all thanx to list for your quick answers to the questions of a 
newbie like me :-)

As a result of this discussion it seems to me to be worth to do more 
investigations on that part and to  play around with rtems and the LPC21xx.
Philips has anncounced a version with integrated ethernet and a version 
with integrated CAN. But how to use these network interfaces with such 
limited memory ? Does rtems has a too large footprint compare with 
systems like ecos etc. ?

It would be quite nice to use only one OS, like rtems, in control 
applications using in a distributed network enviroment consisting of 
controllers of different sizes: rtems working in a sensor as well as in 
a big management or control systems.

I am a novice at rtems. How to do the next steps ?
My ideas is to buy an ARM7 eva board like the EB40 form ATMEL to have a 
stable test basis and to buy a LPC eva board. From that EB40 basis it 
should be not so hard to port rtems to the LPC and  then figure out  the 

Does anyone has experience with the EB40 ? Or can you recommend me an 
other one ?
Can I get further advices from the list if I am in trouble ?
Where can I fiind the propper info redarding the use of RTEMS with ARM7 
to start ?  I  haven't found much ARM7 stuff on the server, esp. in the 
BSP section.
