TUSB422: TUSB422 About UFP Mode

Part Number: TUSB422

Hello~

It is being used as a UFP.

I want to control the charger using TUSB422 but the TUSB422 does not work.

Please check each of the registers below to see what's wrong.

The data read for each register is as follows:

    Hi, Brian~

    I'll wait for some good information.

    I have additional questions.

    With an EVM, everything is solved.

    But the EVM seems to have been discontinued. Is that right?

    yes,it's discontinued, but how you get EVM?

    I'm sorry. I wrote it wrong. I don't have an EVM.

    It is now successful to send a message.

    1. Do not send GoodCRC automatically.

    2. Adaptor(Source) unilaterally send 'Source_Cap'.

    Which register should I check?

    Is PD Rx enabled for SOP?

    Hello, Brian

    0x2F is enabled for 0x01(SOP Enable).

    If you can provide us with a sample code, please send it here.

    shimbg@misum.co.kr

    Then, the power supply is "hard reset" as shown below.

    The data read for each register are as follows.

    Please help me.

    In addition, sending 'Get_Source_Cap' only comes with 'GoodCRC'message.
    The Source Cap message does not come.
