Thanks.

Sure and thanks.

RTEMS is statically linked so object files built as part of RTEMS or files build
as part of your code are equivalent.

I will often create a small application to test new drivers or a new feature for
RTEMS that do not touch the core RTEMS kernel code. I do this because the build
is simpler and faster than rebuilding RTEMS on each edit. This means updating
RTEMS is easy and the code I have is not effected.

Are you able to catch the interrupt, confirm the event is being raised and the
interrupt exits via the RTEMS exit path?
