the Cogswell, this Port is connected to a MUX to allow for both of these functions.
NOTE: Please note that you cannot use both the USB 2.0 OTG Micro-AB Connector and the USB 2.0 Type

USB 2.0 OTG Client Mode and USB MUX
To put the Cogswell into Client Mode, the ID Pin on the Micro-AB Connector needs to be pulled high.
Most USB Micro-B Cables will do this internally. Once in Client Mode, the Cogswell will connect the OTG
USB 2.0 Link to the Micro-AB Connector and disable the USB 2.0 Type A connector using the onboard
USB MUX. At this point the Cogswell can be connected to a Host PC for software image flashing. Please
refer to the Software / BSP section of the Manual for instructions on how to do this.
