TPS65987D: tps65987D

Part Number: TPS65987D

I cannot charge a Samsung Galaxy Note 8 with the TPS65987D evaluation board. The VBUS keeps pulsating. Is this a known issue?

Thanks.

    Hi Arif,

    Can you share the PD logs?

    Kedar,

    Can you tell me how to do that? i.e. dump the PD logs?

    Thanks

    Hi Arif,

    Actually, I would need to see two sets of logs:

    1. PD logs (transaction on the Type-C) using a PD analyzer tool like Total Phase
    2. PD Controller state logs (please refer screenshot below)

    To access this window, you would need to enter the debug mode on the GUI.

    Let me know if you face any issues.

    Regards,
    Kedar

    Reattaching the screenshot. The previous one didn't attach.

    Kedar,

    What command am I suppose to run in this debug mode?

    Also, I am not sure I can get hold of a PD protocol bus analyzer. They seem very expensive!!!

    Thanks.

    Hi Arif,

    The "Download button". This will download a state trace internal to the PD controller. Please copy that to a file and attach it to your response.

    Hello Kedar,

    I am attaching the PD controller State Log as you requested. I don't have a PD analyzer to capture the CC line traces. This failure not only occurs with our design but also with the  TI TPS65987DJEVM evaluation module. On the scope I see the 5V VBUS turns on. There is activity on one of the CC lines and then the 5V VBUS is turned off. The whole scenario repeats over and over.

    Thanks

    Arif

    Hello Kedar,

    Have you made any progress on this issue?  Here is the PD log file.

    Hello Kedar,

    Is this case closed or do I need to start a new one?

    I sent you the controller log and the PD bus log files.

    Hi Arif,

    This is still an active post. I analyzed your logs and it looks like the Samsung device is causing a disconnect.

    Can you share the PD logs after sending a "Get Sink Cap" message from the command list on the TPS65987D. This will give us details on what the sink capabilities of the Samsung device are.

    Please also share your project file for TPS65987D.

    Regards,
    Kedar
