This solved it. My administrator pointed me to Service Pak sp6a, which fixed
the problem.
Thanks for your help. I'm looking forward to learning more about eCos.
Unfortunately, this is a "skunkworks" project, and I am looking into it on my
own time, so progress may be (relatively) slow.
The local gurus decided about 1 yr ago to embed Linux, and now we are having
lots of problems related to non-deterministic scheduling latencies, lack of
priority inheritance, code size, ram requirements, etc. I told 'em at the time
these would be problems, but they charged ahead, anyway. :-( I was new to the
company - but not embedded real-time systems (14 years) - and it was easy to
ignore me. ;-( Rather than believe me that there is a difference between
"real-fast" and "real-time", they are learning on their own, the hard way.
This year, they want to integrate some closed-loop control that is currently on
a separate micro-controller. So, I'll get to teach them about the problems with
non-deterministic interrupt latencies, too. Oh joy ...
I'm hoping the EL/IX Linux API might be a face-saving stepping stone for the
powers that be, which will allow us to swap out Linux for eCos. I have no
permission or allocated time to look into this, but I'm pretty sure that's what
needs to be done. All in a days work.
Thanks again for your help!
