Using Symphony Studio to debug on-target?

Is it possible to use Symphony Studio (Eclipse) to debug DSP code running on target?  I was hoping to find something more efficient than ouputing to the read-from-DSP variables.

 

I couldn't find anything in the manuals about this.  I did see that there's a JTAG tap on the DSP core.  How are other people debugging?  Using the simulator?  Any tips here would be appreciated.

    Re: Using Symphony Studio to debug on-target?

    Hi ToneCore users,

     

    Yes it is possible to use the Symphony Studio Debugging environment.

     

    There is a GNU Debugger with the Compiler that is really not useful on the DSP56364 due to too small memory footprint.

     

    Also there is support for the Macraigor Wiggler to the JTAG interface on the DSP. I am not sure if the connector is on the ToneCore board or not.

     

    But it is possible to interface to the OnCE interface on the Chip with a Wiggler and tools. Domain Technologies also builds a really great tool but is not cheap.

     

    The Debug port on the SoundBite board could also be used if you are clever enough to build a small proto board.

     

    Are any of you Hackers interested in that Debugger interface I would be happy to put it up on a site for you to get access to.

     

    regards,

      Yes, can you describe this debug port?  I didn't find reference to it in the hardware guide.  I assume it's something we can write words to and could wire up to a logic analyzer?  That could be handy.

        The DSP56364 has a JTAG-OnCE port that can be used to connect to the Suite56 DSP tools or Symphony Studio.

         

        I am not sure that the ToneCore pedal has this port brought out to a connector, but it is in the documentation on the DSP56364 Data Sheet.

         

        All Freescale DSP device have this port for low-level code debugging.

         

        Macraigor & Domain Technologies are suppliers of this interface tool and what many DSP engineers use with Freescale and Altium Tools for product development.

         

        One may also use the DSP simulator to debug the code as it is an accurate reference of the DSP design. Many DSP code developers also use this approach when Hardware platforms do not have a Debug port pinned out.

         

        I have attached material relevant to your question and hope that it answers your questions. For another approach to Code debugging, you could buy a Freescale DoundBite board and do some work on that platorm as it is about the same price as the Wiggler approx. $150 for SoundBite board.

         

        regards,
