Part Number: TMS320C5535


hi, While bring up C5535 USB audio streaming demo, in the Windows 10, the USB device is not initialized. Our audio demo documentation mentions that it was tested on Windows 7. Do we need any additional steps to get this working on Windows 10? Attaching the screen capture.

regards,

Frangline.

    Hi Frangline,

    I assume you are using the C55X-USBAUDIO — C55x USB Audio Class Framework Version: 02.00.02.04 Release date: 14 May 2013.

    From the screen shots, it seems the USB enumeration never starts. Make sure you have the following HW setup properly:

    –C55x eZdsp

    –DSP switch SW3 1:OFF, 3:OFF

    –Connect USB cable between Host and USB connector (J1)

    –Connect headphones/speakers to STEREO OUT connector (J4)

    –Connect audio source (mic), to STEREO IN connector (J3)

    –(Option 1) Insert micro-SD card into micro-SD connector (J6). Power eZdsp to bootload code.

    –(Option 2) Connect PC with CCS to XDS100 emulator USB connector (J2). Load/execute code via emulator.

    Which Option are you using? Option 1 or 2

    Best regards,

    Ming

    hi, Thanks for the help. Customer traced the Problem to a faulty USB cable - the demo works after cable change., regards, Frangline.
