MSP430FR2311: MSP430FR2311 (20 pin version) stops at random

Part Number: MSP430FR2311
Other Parts Discussed in Thread: CODECOMPOSER

Tool/software:

Hi,

the MC very often simply stops. The main program ends after the initialisation of interrupts in

    __bis_SR_register(GIE);
    while(1){
        __no_operation();
    }

After some communication via I2C, the MC stops in the line __no_operation. If no programming adapter is connected, it also executes a different number of communications and then stops working. I suspect that this is at the same point.
If the CodeComposer is connected, I see the value 0x0009 in the SR register. Which register should you also look at?
I have also tried to end the main programme with

    __bis_SR_register(LPM0_bits+GIE);

The effect is the same. The breakpoints are all deleted.
Does anyone have any ideas on how to investigate the problem?

Thank you very much for your support.

    Since this loop itself won't progress, I suppose all the program's activities are triggered by external events (interrupts). SR=0x0009 has GIE=1; are the events still arriving? 

    [Edit: I mis-read User Guide Fig 4-9 initially. I removed the wrong answer.]

    Hello Bruce, thank you for your thoughts.
    The programme works for now. After a few working time the programme stops automaticly. CodeComposer then automatically switches to the same view that you see when a breakpoint is reached. I can then click on ‘Resume (F8)’ and the programme continues to work normally. All events are then analysed again. The results of the programme are completely normal. After a while, the programme stops automatically. I can then click on ‘Resume (F8)’ and...
    However, no breakpoints are defined.

    If it were just a problem with the debugger, it wouldn't be a problem. But the programme stops even if it runs without the programming adapter. Then no events are evaluated. Unfortunately, I cannot click on ‘Resume (F8)’.

    Is there a known problem with the debug function on this chip? Is it possible to actively switch off the debug logic at runtime? What can I do to analyse the problem?
