We are trying to bring-up our first iMX6ULL prototype board. Unfortunately, USB is not being enumerated in Windows, so we cannot use mfgtools. I think the reason for this is because we have forgotten to connect USB_OTG1_VBUS and my understanding of the USB controller is that it uses VBUS to detect a device is connected. Is there any way I can work around this using a JTAG to force the USB into OTG device mode? I have been trying various things to force the USB registers, but have so far been unsuccessful. Any help would be greatly appreciated.
