Hi NXP team,

     We are trying to load the firmware from USB OTG and pen-drive is connected in USB OTG port but board is not detecting USB as storage device when we do "usb start" command. when we probe the USB OTG signal It looks like we are not getting power from "USB_OTG_VBUS" pin. but in the rootfs board is detecting the pendrive when we connect through USB OTG port and we are voltage from "USB_OTG_VBUS" pin. So It looks like we might need to enable voltage in uboot software code. Could you please guide us to enable voltage in "USB_OTG_VBUS" pin

Hi,

Have you tried grounding the ID pin to force the operation in Host mode and provide voltage on VBUS? Otherwhere, if ID pin is left floating, the OTG operation will be as Device, and VBUS should be input.


Hope this will be useful for you.
Best regards!
