RTEMS 4.5.0 and standard PC keyboard

[Motiwala, Yusuf Ibrahim (Yusuf)]

Right, It worked after configuring clock driver. Thanks for precise input. 

However, I am not sure why RTEMS developer decided to go with this approach.
I feel blocking mechanism (may be using semaphores) could have been more
efficient and cleaner than polling.

Regars,
Yusuf

My guess is that you based your test on hello, don't have
a clock tick driver configured, and the keyboard driver polls
using a clock tick to control itself.  See ticker for how
to configure a clock tick. 

And BTW are you part of the group that ported RTEMS to a
Lucent DSP?  All my contacts disappeared (one was an co-op)
and I would like to see that effort included in the standard 
distribution.  I can provide names if that helps.
