Hugh,
 
The port of uC/OS to hardware costs nothing as long as the port is
contributed back to Jean's site so he can host it.  The OS is
inexpensive, delivered with the uC/OS book on CD.  I'm not sure of the
deployment costs, though, but I'm sure it's competetive with other OS
offerings, otherwise Micrium would go out of business.
 
I'm not swayed one way or the other on RTOS support in embedded systems,
I've never really had a good re asonto use one.  Even for big embedded
systems with 16 68K boards on VMEbus with 56 simulataneous serial inputs
at 38K4 streaming to a terrestrial datacast system, I wasn't persuaded
to use an RTOS, just interrupts.
 
Oh, and all my code fits well inside 4K for any conceivable task, of
course!  ;-)

	Hi Paul,
	 
	My understanding is that eCOS is highly configurable (via GUI) ,
footprints < 32K are possible and it is open-source with no
up-front/royalty costs.  AFAIK, uC/OS is already ported to LPC2xxx,
however, this OS is not open-source and does require an upfront payment
(see http://www.ucos-ii.com/).

		With only 128K of FLASH on an LPC, you're not going to
get much
		meaningful eCOS code onto a 2106.  Why not port uC/OS?
