are there any dynamic checking tools (a la

More specifically, I'm interested in memory and concurrency checking,
more specifically for ARM.
None that I know of. My limited understanding of these tools is their
use of MMU features to work and the resultant effect on performance make
it difficult to match up with RTEMS's runtime environment. RTEMS being a
single process, single address space makes this sort of thing more
complex and that is not taking into account the real-time issues due to
the added overhead.
In some RTEMS applications I have worked at the application level to
allow the code or parts of the code to run on hosts that support the
tools you list and then I run the code on that host. It requires
planning and investment of time to make this happen but the pay off is
well worth it. You only have to find a few issues to cover the costs. It
is also nice to be able to run the code and see if any issues exist when
chasing a problem on a target.
