If the double bus fault monitor is enabled the processor will reset itself but, if not, it will just halt/hang and can only be restarted with an external reset. It seems the Coldfire has a similar "fault-on-fault" halt which might the culprit. Maybe worth looking at? Regards, Karl --- [email protected] Send a post to the list.
