8 Troubleshooting
8.1 USB Driver Problems
If you connected the Evaluation Board to the PC before installing the SofTec Microsystems
Additional Components, the Evaluation 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 Evaluation Board.
To restore the USB driver (provided the SofTec Microsystems Additional Components have
been installed), perform the following steps under Windows XP:
1.
Connect the Evaluation Board to the PC.
2.
Open the Control Panel (
Start > Settings > Control Panel
).
3.
Open the
“System”
options.
4. Select
the
“Hardware”
tab.
5. Click
the
“Device Manager”
button.
6. The
“uDART In-Circuit Debugger”
device will be shown with an exclamation mark next
to it. Double click on this device.
7. In
the
“General”
tab, click the
“Reinstall Driver”
button. Follow the on-screen
instructions.
8.2 Communication Problems between the PC and the
Demo Board
1.
Make sure that the “BKGD ENABLE” and “RESET ENABLE” jumpers in the “USB TO
BDM INTERFACE” section are inserted.
2.
Make sure that the microcontroller is powered:
Make sure that the “ON-OFF” switch in the “POWER SUPPLY” section selects the
“ON” position;
Make sure that the “VDD ENA” and “GND ENA” jumpers in the “MCU” sections
are both installed.
