Hi Kal,
For the sake of balance, I should point out that at
http://www.zentropix.com/downloads.html you can find rtai_wxr.img, this
is a 'mini-rtai' that we have had available for nearly a year. It comes
with a 'real' application (a weather radar simulation) that shows what
you can expect to get on a small footprint. If you control-c out of it,
you get to a shell prompt and can look at the layout.
RTAI is more than capable of matching the high data rates of RTLinux.
Regards, Stuart
