Yes but it would require a port to a new architecture as well as a BSP for
your target hardware. It is highly desirable to have a simulator to use
while doing the initial bring up. It also helps with automated testing.

There is a CPU Architecture Supplement at docs.rtems.org which covers many
of the issues and how various ports have addressed them.

What toolchain is available? I don't see TriCore in current gcc sources
although there are references online to older versions.
