Setting Up the FTDI Drivers
The USB-to-JTAG dongle is designed to connect to the host PC over a USB interface, which allows software
running on the host (such as a program loading utility or application debugger) to communicate with the JTAG
loader/debug interface on the MAXQ622 microcontroller. It uses the FTDI USB-to-serial IC to communicate
with the USB interface on the PC. Before the FTDI interface can be used, the proper drivers must first be
installed.
Note: The most up-to-date versions of all FTDI drivers and utilities can always be downloaded directly from
FTDI's website at:
. The DS8005 evaluation kit CD contains the latest versions of these
utilities and drivers at the time the CD was last updated.
Installing FTDI Drivers for the FT232RL
All required drivers for the FTDI USB-to-serial IC can be installed by running the FTDI driver setup executable.
To run this executable, navigate to the
install/FTDI_Drivers
directory of the CD and run the executable:
CDM20814_Setup.exe
.
Once this setup executable has been run, you will be able to connect the USB-to-JTAG dongle to the PC
using the USB interface cable.
When the USB cable is connected with USB-to-JTAG dongle, you will see notices in the Windows notification
area that new hardware has been found, followed by a notice that the hardware installed correctly.
If you have difficulty installing the FTDI drivers correctly using the driver setup executable provided on the
DS8005 evaluation kit CD, you can download and unpack the standard driver package, available on FTDI's
website at
www.ftdichip.com/Drivers/VCP.htm
. The driver package can be downloaded from this page and will
be named similar to “CDM20814_WHQL_Certified.zip”, where the five-digit number depends on the exact
version of the driver that is currently available.
