There are two LEDs, green LED (LEDG) and yellow LED (LEDY), which represent the status of
Ethernet PHY (KSZ9031RN). The LED control signals are connected to the LEDs on the RJ-45
connector. The state and definition of LEDG and LEDY are listed in
. For instance, the
connection from board to Gigabit Ethernet is established once the LEDG lights on.

The board has an USB interfaces (using the SMSC USB3300 controller), which is provided by
TsoM Based Board. A SMSC USB3300 device in a 32-pin QFN package device is used to interface
to a single Type AB Micro-USB connector. This device supports UTMI+ Low Pin Interface (ULPI)
to communicate to USB 2.0 controller in HPS. As defined by OTG mode, the PHY can operate in
Host or Device modes. When operating in Host mode, the interface will supply the power to the
device through the Micro-USB interface.

module, 260 Pin edge connector and RJ-45 connector.
lists the pin assignment of USB
OTG PHY to HPS.
