CCS/TMS320F28379D: Watch Window not getting updated with ADC results

Part Number: TMS320F28379D

Tool/software: Code Composer Studio

Hello, 

I was reading ADC channels once in every carrier frequency zero crossing instant. I was continuously refreshing the watch window and was viewing the updated variables with the field background as yellow. But today when I tried to do the same, I was not getting data continuously. Only when I suspend the execution using the pause button in the debug window, I was able to see the updated value. 

I think ADCs are working fine as I was able to see the updated output through DAC instantaneously. Looks like the watch window is the one that is not getting updated here.

Could you please throw some light on that?

    Hello,
    The keys are to have both real-time mode and continuous refresh enabled (or manually refresh). I'm sure you already know this since you had it working before. I'm not sure what would cause this to stop working. Is in an issue of the variables simply not updating or the debugger blocking memory access to a running target? Can you attach a screenshot of what you observed?

    Thanks

    I had to add that register value as watch variable. Then it was continuously updating.
