4.2 USB2MDIO Software

Download the software from http://www.ti.com/tool/usb-2-mdio.

The web-page also contains the user’s guide for installing and using the software. Since MSP430 is on board the EVM, purchasing a separate MSP430 Launchpad kit to connect to the PHY using wires is not required. The entire EVM can be powered and controlled via USB connector. MSP430 and USB2MDIO utility can be used even when power is not supplied via USB.

In case the onboard MSP430 cannot be used due to some reason, MDIO and MDC pins are also broken out on J10 connector. Customers can connect a MSP430 launchpad or their own MDIO-MDC utility on J10 to access the PHY registers.
