Hi ,


In MCIMX7D7DVK10SC, in USB_OTG1 is used for diagnostics purpose connected to microUSB connector. We are going to use the same USB connector for charging our wearable device. Shall we connect the USB_OTG1_VBUS pin to VBUS pin of USB connector or shall we leave it floating?


In other words, are we still able to use USB_OTG1 to access IMX7 for diagnostics purpose even if we left VBUS of IMX7 floating? (i.e, connecting only DP and DN from USB charging connector to USB_OTG1 port of IMX7)


Thanks & Regards,
