    Hi Kangning,

    Could you provide some more details of your setup so that we can try to reproduce the issue on our side? I think a photo of the setup including the EVM would help.

    The specific EVM Settings are shown in the figure, in which the working voltage is normal, the IDENTIFICATION of USB hardware driver is normal, and the hopping pin Settings are shown in the figure. The retention or removal of J3 and J4 on TAS2564 has been tried, because my experiment is mono channel. There are four addresses for J12 and J13 in total, and the I2C error is still reported, may I ask what is the problem

    Hi Kangning,

    Could you try setting the IOVDD to 1.8V? You can follow section 5.3 of TPS2564 EVM User's guide (link below) for this change.

    Hi Atiq

    It  has been changed according to the diagram in Section 5.3, and the above I2C error still exists. IOVDD has been modified 1.8V before, and the above problem still exists. No matter the default configuration, mono configuration in Section 5.3, or the four addresses of I2C and their corresponding permutations and combinations have all been tried, and the same problem still exists  .

    Regards

    Hi Kangning,

    Do you have any other TI Audio EVM that is functional? I am wondering if this could be a potential EVM board level issue.
