Unused USB_OTG2_VBUS pin of i.MX6SX

[torus1000]

Hi,

According to IMX6SXCEC sect.4.2.1 Power-Up Sequence :

  [only] USB_OTG1_VBUS and USB_OTG2_VBUS are not part of the power
  supply sequence and may be powered at any time.

Is it OK to leave USB_OTG2_VBUS pin float if I don't use USB OTG2?

Or I should pulldown with 10k ohm resister?

Can anyone help me?

Hi torus1000

yes it is ok to leave USB_OTG2_VBUS pin float if one don't use USB OTG2.

It is described in Table 2-17. Recommended connections for unused analog interfaces
