I don't think breakpoints are doable without support from IFI in a Master Code update. The Master processor's watchdog timer will time out and freeze the whole controller if you stop in the user code for any appreciable amount of time. And as far as I know, we don't have any direct inputs into the master controller to do anything about this. I suppose you'd have to somehow modify your code to stop processing user functions and code, but continue looping and updating control values.... Mostly it sounds incredibly complicated and quite likely to break any fragile code you happened to be trying this on.
