PROCESSOR-SDK-C6747: Code for Audio Preprocessing System Reference Design for Voice-Based Applications Using C6747 TIDEP-0099

Part Number: PROCESSOR-SDK-C6747
Other Parts Discussed in Thread: OMAP-L137

I would like to use TIDEP-0099 reference design as a starting point for my project.  I have installed CCS and OMAPL137_dsp_setupwin32_1_00_00_11. 

I have a hard time locating demo code for TIDEP-0099.  There is a similar audio processing demo but for a different processor in OMAPL137_dsp_setupwin32_1_00_00_11.

Is the code example for TIDEP-0099 available.  If so, where can I find it?

Thanks

    Hello,

    The audio-preprocessing demo is provided in Processor SDK. After installation, the example code can be found under ~\processor_sdk_rtos_omapl137\demos.

    Documentation can be found here:

    Dear Sahin,

    Thanks for getting back to me promptly.  I have gone through the links you sent already.  I installed SDK and in the folder

    processor_sdk_rtos_omapl137_4_00_00_04\demos\audio-preprocessing\file_demo_bios\omapl137

    I found a readme file with following instructions:

    ...

    11. Import DA830_bf from C:\ti\audio-preprocessing-fw\file_demo_bios\da830
12. Build the imported project
13. Import the target configuration file DA830_DSK_USB560M.ccxml from C:\ti\audio-preprocessing-fw\file_demo_bios\da830
14. Connect the Blackhawk USB 560M JTAG to J4 on DA830 DSK
15. Power on the DA830DSK
    ...

    My confusion comes from the EVM board in use - DA830DSK. TMDSOSKL137 SK as described in the demo is not mentioned anywhere.

    What am I doing wrong? Am I using a wrong SDK version?

    I downloaded SDK from the TI website because TMDSOSKL137 SK that I ordered is sill in transit.
    Is the SDK that I downloaded from TI website newer version and uses possibly a different DSK?

    All I want to do at this point is reproduce demo TIDEP-0099  with OMAP-L137 SK since I already ordered it.
    As of now, webpage still shows that the demo TIDEP-0099 is using TMDSOSKL137 SK.


    Thanks again

    Hi Igor,

    Sorry for the confusion. The DA830 is equivalent to the OMAP-L137. I suspect this example was initially created for the DA830 which is why you are seeing it referenced in the readme.

    To build and run the example, please follow the steps in the RTOS Developer's Guide.
    software-dl.ti.com/.../Examples_and_Demonstrations.html

    You'll see a section specifically for the OMAP-L137 EVM under the sections titled "How to Build the Demo" and "How to Run The Demo." There is a section for the File Based Demo and one for the Circular Microphone Board Demo.

    I hope this clears things up. If you have any further questions please let me know.

    Thanks again for getting back to me Sahin.  If DA830 and OMAP-L137 are equivalent, then everything is fine.

    Thanks for the help.

    Best regards
