Note the green LEDs (on the Ethernet connector of the
QVGA Base Board
) that flash every time an
Ethernet frame is received. You should be able to see the LED flash at the same rate as the ping
packages are sent. Other communication on your Ethernet network might make the LED flash much
faster than this.

FTDI USB Driver Installation
A USB driver must be installed on your PC computer in order for the USB-to-UART chip (FT232R) to
function. Make sure to download the latest version of the driver, which can be found at the following
URL:
http://www.ftdichip.com/Drivers/VCP.htm
Search for a FT232R driver for your operating system. Also see FTDI‟s installation guides for details
how to install the driver for different operating systems:

When the
QVGA Base Board
is connected to the PC (via an USB cable) the PC will ask for a driver.
Unpack/unzip the downloaded driver file and browse to the position of the driver files. After successful
driver installation, a COM port will be created. Before communication with the Board can take place the
UART settings must be correctly set. The following description is valid for Windows™ XP, but other
operating systems have similar dialog windows. See the USB driver documentation for details, if
needed.
To change UART settings, first open the System Properties dialog, as illustrated in the figure below.
Figure 10 – System Settings Dialog
Then select the
Device Manager
and then open the
Ports
list, as illustrated in
Figure 11
below.
