Part Number: PROCESSOR-SDK-AM335X
Other Parts Discussed in Thread: AM3352, TPS65910

Tool/software: Linux

Hey Team !

I am trying to interface lan9514 with am335x but it is not getting enumerated .Can you give some light to move forward. I am attaching the log of my boot process. The device tree entity which i have used is like

&usb0 {
        status = "okay";
        dr_mode = "host";
};

    Hi Pranav,

    Is that only lan9514 not enumerate, or the host port doesn't enumerate any other  device at all?

    Please run the following script on your board after booted Linux, and provide the output.

    Hai ,

    Thank you for your response.
    Lan9514 is only not getting enumerated ,so the usb device and ethernet which which is there corresponding to the chip is not comming up.

    Below is the output from the script.
    --------------------------------------------
    USB is initialized
    Warning: CONFIG_USB_MUSB_DUAL_ROLE undefined.

    Pranav,

    The log shows the USB controller seems to be in the correct state to enumerate any device attached.
    Other than the lan9514 device, have you tried to attach any other usb device to see if it get enumerated?

    By the way, the kernel boot log you provided shows EHCI driver is loaded. You shouldn't enable EHCI driver, as AM335x doesn't have an EHCI controller.

    Hi,

    I haven’t heard back from you, I’m assuming you were able to resolve your issue. If not, just post a reply below (or create a new thread if the thread has locked due to time-out). thanks.

    Thanks for the response and sorry for being late . The issue got resolved ,in my hardware USBRBIAS pin was floating that was the mistake.
