    Hi Kevin,

    To execute a 4CC command, you first need to send the input data to the Data register (0x9 for Data1). After sending the input data to the data register, the 4CC command can be sent to the CMD register (0x8 for CMD1).

    The Power DUO source EVM file is included in the TPS6598x application customization tool. Just select TPS65987D after clicking New Project and two of the options will be for the sink board and source board from the Power Duo. The 87EVM recovery image is also included in the GUI, just click on Device --> Re-Flash EVM Firmware (Recovery). One of the drop down items is for the TPS65987EVM.

    Thank you,
    Eric
