The on-board MSP430 comes pre-programmed and ready to use. When using this EVM for the first time on a
®
Windows
7 (or above) PC, MSP430 drivers and USB2MDIO software utility has to be installed. USB2MDIO
software can be used for accessing registers.
4.1 MSP430 Driver
Install the latest MSP430 drive from this website:
msp430/MSP430_FET_Drivers/latest/index_FDS.html.
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.
