Hello,

we are planing to use USB to flash the eMMC.

We let the pin C20 USB0_DRVVBUS open. Is this ok or does it need to be connected?

Regards,

Dusan

    Hello Dusan

    Thank you for the query.

    I assume you have configured the USB0 interface device for device mode.

    In device mode a switched 5V VBUS input is expected to be applied to the USB0_VBUS pin from an external input.

    There is no requirement for control of power switch. Leaving USB0_DRVVBUS is not a concern.

    FYI, the DRVVBUS has an internal pulldown enabled during reset.

    You could consider adding a TP to this pin for future usage.
