dear all
Refer to the SCH_HDMI_DONGLE_MX6X_REVB2_20130116_1500, the pin of EIM_D21 is used as USB_OTG_OC. MX6Q_PAD_EIM_D21__USBOH3_USBOTG_OC,
And when the status of USB_OTG_OC change , how the software can detect ?
Is there some register can be read when the USB_OTG_OC is low or high?
Solved! Go to Solution.
USB_OTG_OC signal is intended for overcurrent event from a USB power scheme,
providing VBUS for external device, assuming i.MX6 OTG is in USB host mode.
OCC and OCA fields of USB PORTSC1 register are affected by USB_OTG_OC signal
state.

Hi,
i am interested in this.
Why for example sabrelite is not setting this pin (KEY_COL4) as GPIO ? Is it not necessary ?
