Real-time debugging: unique to C2000?

Anonymous

Hi All,

 

I would like to ask a question about real-time debugging.

 

I have seen that on E2E page http://e2e.ti.com/videos/m/microcontroller/239645.aspx, there is a video example showing how to do real-time debugging for C2000 chips. Value change of variables (or probably registers) can be seen when the program is running without halting the program. I have to say this feature is really super-cool. Even in MS Visual Studio there doesn’t exist such considerate and intuitive function.

                

          

                

           

            

In that video, I observed that there is an “Enable real-time mode” toggling button on the upper toolbar of CCS4 (please see above). I then tried to find the same button in my CCS4 whose target configuration is for a DavinCi 6437 EVM board. I searched carefully on the toolbar during debugging, but could not find this button.

                                     

                                  

                     

In the C2000 video example, I notice that the “Enable real-time mode” button is placed between “Reload program” and “Debug launch” button. In my 6455 configuration these two buttons are direct neighbor without any button between them.

 

So my question is:

1.    Is real-time debugging a feature unique to C2000 chips?

2.    If not, does DavinCi chips support it? Does ARM9 (AM17x, AM18x) chips support it? How should it be enabled?

 

Sincerely,

Zheng

    Zheng,

    It is a feature that is enabled by capabilities in Silicon.  It is supported by C28x, C64x and C55x, but most commonly used on C28x.  It is not available for ARM.  In your second capture you are running on a simulator, the feature is not available on simulators.  If you connect to the DM6437 EVM the feature should be available.  To enable real-time mode launch a debug session, go to the tools menu, select generic debugger options and scroll down to the real-time options area and select "Enable silicon real-time mode...".  Note that you will and to disable real-time mode prior to loading a program and enable it again afterwards.

    Regards,

    John

    Dear John,

    Thanks for the answer.

     

     

    1. I selected "Enable silicon real-time mode" in the generic debugger options per your instruction, but I still cannot find the button for real-time mode toggling as in the C2000 video. What should I do to enable it?

    2. When you say "It is a feature that is enabled by capabilities in Silicon" and in the generic debugger option name "Enable silicon real-time mode", does "silicon" mean this feature requires hardware support, rather than merely an upper-level IDE feature (very sorry for this layman's basic terminology question) ?

     

     

    BR,

    Zheng,

    If the buttons are not showing up you can add them.  Right click in the toolbar area and select "Customize Perspective".  There is also a menu item on the Window menu.  Click on the Commands tab and check the box for Real Time.

    There is debug IP in the device itself that enables real-time mode.

     

    Regards,

    John

    Dear John,

     

    I followed the steps but was unable to find "Real Time" in the options. Why is that? How can I enable the option?

    Zheng,

    You are probably using an older version of CCS. That toolbar was added in a later version. Try updating your version of CCS.

    Thanks

    Hi,


    Since you mentioned Visual Studio, there is a third party tool that enables real time debugging, meaning it runs in parallel to your application and can be used to sample and inject data remotely into the module.

    Since the tool is not linked in any way to the debugger, you can use both the VS Debugger and the tool.

    Check vsdevaids.webs.com for more details if you feel interested.

    It even features real time graphs of app internal data, waveform stimulus injection and many more.
