Based on the Toradex Pinout Designer, we see a conflict between USB and CAN1. We are considering using USB OTG (as a slave) and CAN1. Is there a conflict here?
The USB_O1_HOST_MODE (USB_OTG_HOST_MODE) is not used in our standard USB driver. It is a non-required signal. Even tough is possible to use the USB interface only with the D+ and D- signal lines, I recommend using the same signals as described in our carrier board design guide in section 2.5.1. All signals that are not listed in this document can be left unconnected without issues.
