Description
Will there be some kind of bus watchdog to catch invalid accesses or lock ups (missing 'heart beat' signal)? I think this is an important development aid, but it could also be configured to restart the system in the event of a violation being caught and reported by CHERI... rather than just leaving the demo 'IoT system' in a dead state.
