Switch USB role

Salvatore1z — Tue, 19 Jan 2016 15:02:50 GMT

Hi,

I know that iMX6 has a OTG enabled USB controller and I would like to know if an API is available to change the role of the USB controller dynamically from host mode to device mode.

I expect to call this API from user space.

After calling the API I exepct the USB host stack to go down and the USB gadget stack to come up.

Thank you.

Salvatore

Hello Salvatore,

You need to control the USB_OTG_ID pin in order to change from one to another here is another thread that you can follow regarding this topic:

Have a great day,
