Working with TMS320C6713 DSK

I am working with TMS320C6713 DSK for speech signal processing. MATLAB simulink is interfaced with CCS compiler v3.1 .Build process is complete.How to give audio input to TMS320C6713 DSK  through MIC IN?? While loading program in CCS compiler an error occured as Data verification failed ,How to fix it???

    You have to LINE IN for the audio input.


    While loading program in CCS compiler an error occured as Data verification failed ,How to fix it???

    Did you run the gel file before loading the code (by default gel file would run) ?
    Can you paste the error log here ?
  • Ya..MIC IN of ADC is connected to Embedded matlab function, inside the matlab function block ,coding for denoising is given.And then embedded function block is connected to DAC .While building with ctrl+B codes are generated and compiled in CCS compiler automatically with 0 errors and 12 warnings..But i cannot hear any sound from the headset connected..can you help me with this??How to proceed after this??
  • To proceed, you might want to look at Titus' comment that you need to use the LINE IN and not the MIC IN. Have you tried that?

    Another thing to look at is all the warnings you have. I am never satisfied with any warnings in my code because they often hide hard-to-find code bugs.

    Start from known working code, assuming you are using the EVMC6713. You can go to TI.com and search for "c6713 workshop" (no quotes) to find the DSP Integration Workshop that is archived on the web. From those files, you will find helpful instruction to learn about using the C6713, using the Code Composer tools, building an application without warning, and constructing a series of applications that use the features you are trying to use.

    If you start from something that works, you will save yourself a lot of time trying to figure out why yours does not work.
