Pin processing when USB interface is not used of i.MX6Solo.

[takashitakahash]

Hi community.

Our customer has question below.

Please tell me about pin processing when not using USB analog interface.
,
IMX6DQ6SDLHDG does not describe the processing of F9 (VDDUSB_CAP), V5 (USB_OTG_PWR), T4 (USB_OTG_ID).

Could you tell me how to handle the terminals?
As USB is not used, is itcorrect with GND short?

Thank you.

Best Regards.

Hello

1.
VDDUSB_CAP requires capacitor if the internal regulator is used, otherwise -may be left float.

2.

  USB_OTG_PWR, USB_OTG_ID may be left float, assuming default GPIO mode of corresponding pins.

Have a great day,
Yuri
