  • Hi Team

    It still doesn't solve my problem. May I return the product? Thanks



  • Hi, Dora,

    Are these 2 boards TI evaluation modules, and one works but not the other? 

    I am not familiar with the return process, I'll have to check.


  • Hi  Rex

    Thanks for reply.

    You can refer to the following video and circuit diagram. We think the performance of the evaluation board is poor, please help to verify, thank you.3644.ov1-dsp-dvk_SCH(1)_看图王.pdf
