Agreed! I thought that RTAI had some sort of commitment to have RTAI
running on
a wide variety of CPUs, and they at one time did have ARM support. I
thought the Beagle
would be an EXCELLENT platform for real time embedded experiments of all
sorts (robots, autonomous vehicles, etc.) So, I really didn't expect
this to be a multi-YEAR
project, I assumed that if I provided the system, it would be relatively
easy to finish
the port. But, that was apparently VERY wrong. The last supported ARM-RTAI
kernel was something like 5 years out of date, and the Beagle's OMAP3530
has MANY
bells and whistles that need drivers and kernel code.

And, of course, the REAL question is, after getting a suitable RT
kernel, would LinuxCNC
actually run acceptably on a Beagle Board or similar machine? Memory is
a bit
limited, CPU speed may or may not be a problem (hard to compare such
different
CPU architectures) would the OMAP I/O architecture actually perform OK in
an R/T environement.
