Hello. I'm designing a new custom board based on IMX6Q processor. My board will use USB OTG only for serial boot so in "device mode". I never will use host mode of OTG. Following my question:
1) I use mini USB B receptacle connector, and I left the USB_OTG_ID always pulled up inside the board.
2) On USB mini B connector I leave +5V pin unconnected, and I connect th USB_OTG_VBUS on IMX6 to the +5VCC internal voltage (generated internally the board).
3) The only connections on mini B USB connector are USB_OTG_DN, USB_OTG_DP and USB_OTG_GND .
Is that correct for a OTG in a fixed "Device " mode?
