2.2.3.2 USB-2-MDIO Software

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

The webpage also contains the User’s Guide for installing and using the software. Because the MSP430 is on-board the DP83826EVM, it is not necessary to purchase a separate MSP430 Launchpad kit and connect to the PHY using wires.

In the case the on-board MSP430 cannot be used for some reason, MDIO and MDC pins are also broken out on J1 and J2 pins, respectively. Users can connect an MSP430 launchpad or their own MDIO-MDC utility on J1 and J2 to access the PHY.
