66AK2G02: Confirm whether TI provide the SDK for K2G EVM with AUDK2G

Guru 24520 points

Part Number: 66AK2G02

Hi TI Experts,

Please let me confirm the following question.
Does TI provide the SDK for K2GEVM with AUDK2G?
I know that TI provide some SDKs as below, but I could not find the usage wiki or documents for AUDK2G.

Also, according to this post, it seems that TI will provide the special SDK for this card.

If yes, would you please teach me the status?

If you have any questions, please let me know.
Best regards.

  • Hi Kaka,

    I've forwarded this to the software experts. Their feedback should be posted here.

  • Hi, Kaka,

    It will be nice if you can specify which OS for less confusion.

    In Linux, the McASP driver is supported in the ProcSDK release for K2G. If you take a look at the keystone-k2g-evm.dts device tree file, mcasp, sound0, and simple-audio-card configuration are provided. The sound card is tested using aplay utility.

    If this answers your question, please close this thread. Thanks!

  • Kaka,

    We have integrated the basic drivers to access the functionality on the Audio daughtercard into the Processor SDK RTOS using the AUDK2G driver that is added in the addon folder of the SDK. The example currently integrated in the SDK does 8 channel anlog audio loopback using the audio daughter card:

    YOu can find the details of this feature on the wiki documentation here:

    the digital loopbback example will be integrated in the SDK soon.

    The audio SDK that is discussed on that e2e thread is specifically for customer who want to leverage Performance Audio framework that allows users to encode and decode Dolby/DTS content and run performance audio algorithms(ASPs) like virtualization,etc as discussed here:

    this offering should be available to customers for DA10x in 2Q17. Please contact your local TI contacts if you are interested in this offering.

    Hope this helps


  • Hi All,

    Thank you for your some kind comments.
    I would like to know about catalog device.
    Do you have a plan to add other sample codes/demos for AUDK2G except for digital loopback?

    If you have any questions, please let me know.
    Best regards.
  • Kaka,

    For AudK2G board current plan is to support only analog and digital loopback codes leveraging the MCASP LLD and AUDK2G software driver. All application level functionality will be provided using the Audio SDK (RTOS based).

    In addition to audio daughter card support with K2G EVM, we also plan to support a circular microphone based TI Design which should be available by end of 1Q17. Please reach out to your TI contact for more information.

    If you have specific usecase where we can provide more examples, please let us know and we can evaluate and try to add these examples to the SDK.




  • Hi Rahul,

    Thank you for your comment.
    My customer would like to evaluate the adaptive noise control.
    But we do not have that information about this signal flow in details now.

    Best regards.
