Hi,

In my AM5728 custom board ,USB2.0 is not enumerating the plugged Pen-drive.

The error log is:

    Hi Prraddhep,

    Could you specify what SW release and kernel version you are using? Is the problem appear with other USB devices?
    Could you execute 'lsusb' command before connecting pen-drive and after that when the pen-drive is already connected and errors are displayed?
    The output of 'dmesg' command also could be useful.

    Hi Cvetolin,

    Thanks for your replay.

    I am using TI SDK version "ti-processor-sdk-linux-am57xx-evm-02.00.01.07" and  kernel version is 4.1.13.

    With  different USB devices also same error is repeating.

    Please fine the Dmesg logs before connecting and After connecting USB device.

    Prraddhep,

    The error code "error -71" which appears in the console log means "Protocol error". Could you successfully connect some other USB device (not usb pen-drive only) for example USB mouse? If there are errors with each one USB device I suspect a problem with USB lines (swapped or incorrect connected or broken connection) on the board.

    Hi Cvetolin,

    Thanks for your replay.

    USB MOUSE is detected with USB2.0.
    Why pendrive is giving protocol error can i enable any drivers?

    Thanks,

    Prraddhep,

    The further investigation of the protocol error can proceed via analyzing the USB communication. For example you can connect a USB hub between the board and pen-drive. Also you should connect to the USB hub a PC with some capture and analyzing software (but unfortunately I can not recommend you such good enough analyzer). I hope that the analyzer could find the reason causing protocol error if it is really presents.

    Prraddhep,

    The schematics reviewing is out of scope of the E2E forum but con contact with local TI representative to negotiate schematics reviewing.

    Hi Cvetolin, No problem.

    Please clarify one thing,In AM5728 EVM  USB2.0 default to client mode.

    We have designed for USB2.0 as  HOST mode,In our case USB2_DRVVBUS enables the 5V power source to VBUS of USB connector this VBUS voltage   has given to PMIC VBUS is it correct ?

    Thanks,
