Stellaris® LM3S9B90 Evaluation Kit
The Stellaris LM3S9B90 Evaluation Kit for Ethernet and USB OTG provides a low-cost way
to start designing Ethernet and USB OTG applications with Stellaris microcontrollers. The
LM3S9B90 Evaluation Board (EVB) functions as a complete evaluation target that also
includes a debugger interface (BD-ICDI) that can be used to program and debug the
evaluation board as well as any other external Stellaris device. The included USB cable is all
that is needed to provide power and communication to the host PC.

Requirements
You have a PC, with a USB interface, running Microsoft® Windows 2000, XP, or Vista.
You have the Stellaris LM3S9B90 Evaluation Kit Documentation and Software CD
Board Set-Up
The LM3S9B90 Evaluation Board is configured for immediate use. First, connect the
LM3S9B90 Evaluation Board to the ICDI board using the 8-pin and 10-pin ribbon cables
included in the kit. The 8-pin cable inserts into the header labeled PWR/UART on each board.
The 10-pin cable inserts into the header labeled JTAG/SWD on each board. To power the
EVB, use the USB-miniB to USB-A cable supplied in the kit. Connect the miniB (smaller)
end of the USB cable to the connector labeled "USB J4" on the ICDI board. Connect the other
end (Type A) to a free USB port on your host PC. The USB is capable of sourcing up to 500
mA for each attached device, which is sufficient for the evaluation board. If connecting the
board through a USB hub, it must be a powered hub.
Important Note: The next step explains how to install the FTDI drivers for the board. Some
customers with previous installations of the FTDI drivers may experience trouble when
installing newer (2.02.04 and later) versions of the driver. The problem only seems to affect
users of Windows XP, and not Windows Vista. If you have any problems with the driver
installation, go to www.ti.com/lm_ftdi_driver
When you plug in the EVB for the first time, Windows starts the Found New Hardware
Wizard and asks if Windows can connect to Windows Update to search for software. Select
"No, not this time" and then click Next.
