I had a brief look over the documentation you provided but could not see how to
achieve the result you are saying.

Is there an example of how to do this?

Missed the TBR. But as long as there is no better place ...

I hope that I didn't start a discussion about the site just now ;-)

Please add it even though officially TBR is to be removed..the idea was to
find a new way to capture the info in any TBR page when we moved to Trac.
But there are so many still.

One is a duplication of getting started procedure between a TBR page and
the Users Guide. Need to review to.make sure Users Guide is best version,
change all references to old page, etc

Hello Joel,

space missions are always a great example for the widespread use of
RTEMS (in that case in terms of kilometres). So is there any reason that
would prevent this probe to be added to the list in the RTEMS wiki:
https://devel.rtems.org/wiki/TBR/UserApp/RTEMSApplications#SpaceandAviation

I can add it if you want. I just wanted to make sure that it wouldn't be
a problem before doing so.

Do you have any more (publicly available) details about where RTEMS is
used in that probe?

Best regards

Christian
