Evaluation Of RTOS

I have been given the task of trying to survey customers of "Green Hill
Software's Integrity" and "Wind River's VxWorks" for Carnegie Mellon
University.  I would really appreciate being able to talk to any of you
who have experience with one or both of these products.  If you don't
have any experience with these products, but do have experience with
finding customers for this kind of surveys then you thoughts would be
appreciated.

(I am mostly interested in their DO-178B and ARINC 653 products.
Realizing this is a very small group I would like to hear from
customers and users of their main product line as well.)

If I am using these group incorrectly then please let me know and I
will cease and desist using this forum this way.

Thanks You

I worked with wxWorks for many years ... ten years ago. it was a fantastic
product then (we ported it on a sparclite proprietary board).

The company I worked for then was OCE Graphics (I believe OCE Industry today
- I think they're based in Venlo Deutchland - but the branch that used it
was in France: Maison-Alfort).

I do not know if they still use it.

Regards,

Philippe

Groups such as comp.os.vxworks might net you more responses.

Though it has been about 3 or 4 years since I did a full analysis.  I
found a lot of information and RTOS comparisons at:

http://www.realtime-info.be/encyc/

A couple of years ago I found QNX and VxWorks were the best as far as
true hard real time OS and well tested BSPs or HALs for various
platforms.  Good tools and support also.  Integrity was also good if
your on a budget.  OSE was the biggest pile of crap I have ever used.
There BSPs and HALs were untested and buggy on the PXA255 processor
that I was using even though they were adimate that it was fully tested
and working.

But these days with the various POSIX flavors, faster processors and
heaps of driver/BSP/HAL support.. I would go one of the real time LINUX
OSs.  I used WinCE as well and it is pretty handy as far as getting
something up and running quickly but then you have the tragic support
issues and all the other Microsoft anomolies.  actually it wasn't too
bad.. I hate to admit.  :(  But LINUX is free.. go LINUX!!!!

My experience is that VxWorks, has old tools, very unfashioned, 
virtually no support, and no further development. Stay clear of this. 
Besides all it's very expensive, has nearly none device drivers at least 
in the x86 market....
