Modifying MicroZed for USB Device Interface

Former Member

I would like to use the MicroZed as a USB Device (not Host). What hardware modifications are needed to do this? Are there any HID USB drivers that would run on a bare metal platform?

    Hi pschur,

    The modifications required are covered on Sheet 5 of the Rev. F schematic.  These changes are also covered in the MicroZed HW User Guide.

    MicroZed USB PHY is preconfigured for Host Mode operation by default.  The USB PHY can be configured for Device Mode operation through a set of hardware component population options.

    To modify MicroZed for operation in USB Device Mode, perform the following hardware changes:

    u2022tReplace R56 with 10K Ohm resistor
    u2022tRemove R50
    u2022tRemove L10 (Not populated by default)
    u2022tRemove C1 (Optional)
    u2022tRemove C3 (Optional)

    There is also an example posted in the MicroZed Reference Designs/Tutorial section which gives a SW example turning MicroZed into a small USB Mass Storage device.

    Regards,

    -Kevin
