Hi NXP team,

Am very sad to inform you that I didn't get a response to previous emails.

Expecting your support for the following query.


1. In our custom board based on i.mx6ULL, we are only using the board only in USB device mode. For this, the Vbus(in our case it is USB_VBUS_iMX) voltage is necessary to connect to the i.MX's T12 pin??????(from HDG document I came to know that VBUS has no part in Power up sequence)

2. In the NXP EVK, we found a circuit as below. May I know the necessity of the same(Related to concern No:1)?

3. USB Data transfer detection is possible in i.MX? If yes, please provide the necessary details for implementing the same.
