9 Troubleshooting
9.1 USB Driver Problems
If you connected the Demonstration Board to the PC before installing the SofTec
Microsystems Additional Components, the Demonstration Board’s USB driver may not have
been correctly installed on your system. Unplugging and replugging the USB cable is of no
use, since Windows has marked the device as “disabled”. As a consequence, the PC cannot
communicate with the Demonstration Board.
To restore the USB driver (provided the SofTec Microsystems Additional Components have
been installed), perform the following steps under Windows XP:

9.3 “LED0” LED Always Turned On
The “LED0” LED shares the BKGD line (used for the BDM communication). If you want to use
this line as a generic user I/O you must enable this feature in your application software and
remove the “BKGD” jumper in the “USB TO BDM INTERFACE” section of the board. Doing so,
Connect the Demonstration Board to the PC.
Open the Control Panel (Start > Settings > Control Panel).
Open the “System” options.
Select the “Hardware” tab.
Click the “Device Manager” button.
The “uDART In-Circuit Debugger” device will be shown with an exclamation mark next
to it. Double click on this device.
In the “General” tab, click the “Reinstall Driver” button. Follow the on-screen
instructions.
Make sure that the “BKGD” and “RESET” jumpers in the “USB TO BDM INTERFACE”
section are inserted.
Make sure that the microcontroller is powered (The “VDD” jumper in the “POWER”
section must select the “ENABLE” position).
Make sure that the “POWER SEL” jumper selects the appropriate power source
(typically “USB” when the board is connected to the PC).
Make sure that the microcontroller is correctly inserted in its socket.
