i.MX6UL USB OTG

martinwerner — Mon, 24 Jul 2017 11:16:33 GMT

I have a question regarding the USB OTG interface on the IMX6UL. I am using the i.MX6UL in a custom Hardware Design and I am wondering if it is neccessary to set the ID Signal High or Low by external Components. I need a lot of Interfaces and Analog Inputs, so the muxed Pins ID, OC and PWR are blocked by other functions.

Is it possible to set these by Software?

Best regards

Martin

BTW: I want to use the i.MX6 as USB Host.

Hi Martin

per usb specification ID signal should be high (or float) in Device mode,

low in Host. It is used by linux driver, I am afraid it is not possible to set it by software

without additional modifications in linux sources.

Best regards
