USB-2-MDIO Software

Download the software from

http://www.ti.com/tool/usb-2-mdio

. The Web page also contains a User’s

Guide for installing and using the software.

The MSP430 is on board the EVM, so it is not required to purchase a separate MSP430 Launchpad kit
and connect to the PHY using wires. The entire EVM can be powered and controlled through a USB
connector. MSP430 and USB2MDIO utility can be used even when power is not supplied through a USB.

In case the onboard MSP430 cannot be used due to some reason, MDIO and MDC pins are also broken
out on the J15 connector. Customers can connect a MSP430 launchpad or their own MDIO-MDC utility on
J15 to access the PHY registers.
