The USB OTG  Sabre board

Hi, can I have help with this question.


Using WIndows OS using an i.MX6 Sabre Board:


The USB OTG board is the only USB port exposed by the Sabre board so we had to use it when connecting a USB stick with the Windows image.

Since it is an OTG code, we had to configure it by the UEFI software to ‘host mode’.

My question is, is there a way to lock the OTG port to ‘host mode’? Locking means, configuring it so ‘reset port’ does not revert it back to ‘idle’.

I have noticed that GPIO_1 can be configured as USB_OTG_ID. Does that have any effect on the USB OTG  port configuration, or can it be used for the “locking” the ‘host mode’ configuration?
