AM2611: AM261x USB Host support

Part Number: AM2611

Hi team,

 

Want a clarification.

Is host mode supported on AM261x?

SDK docs say it is not supported. (picture below)

But we also have an app note with the implementation of True host USB:

Would it be possible to clarify this for me?

Do we have any examples available to share?

 

Best,

Simeon

    Hi Simeon,

    The USB hardware in AM261x supports USB device mode and USB host mode. 

    The current software driver only has support for USB device mode and not the Host mode.

    The appnote that you have linked is "enabling host detection" via hardware mechanism by probing the USB VBUS line. This does not mean enabling the "USB Host itself". By default, the USB On AM261x does not probe the USB VBUS line to see if the USB device is connected to a host. The appnote clarifies that this feature can be enabled.

    Regards,
