8. Troubleshooting
Use the tips in this section to diagnose problems with the Breakout Board.
8.1. LEDs Do Not Flash
If power is applied but the board does not flash according to the preprogrammed counter demonstration, then it is
likely the board has been reprogrammed with a new design. Follow the directions in the
Demonstration Design
section
to restore the factory default.
8.2. USB Cable Not Detected
If Lattice Diamond Programmer or ispVM System does not recognize the USB cable after installing the Lattice USB port
drivers and rebooting, the incorrect USB driver may have been installed. This usually occurs if you attach the board to
your PC prior to installing the Lattice-supplied USB driver.
8.3. To access the Troubleshooting the USB Driver Installation Guide
To access the installation guide for Diamond software and standalone Diamond Programmer:
1. Start Diamond or Diamond Programmer and choose Help.
2. Search for USB driver or Troubleshooting, then select the Troubleshooting the USB Driver topic.
3. Follow the directions to install the Lattice USB driver.
To access the installation guide for ispVM:
1. Start ispVM System and choose Options > Cable and I/O Port Setup. The Cable and I/O Port Setup Dialog appears.
2. Click the Troubleshooting the USB Driver Installation Guide link. The Troubleshooting the USB Driver Installation
Guide document appears in your system's PDF file reader.
3. Follow the directions to install the Lattice USB driver.
8.4. Determine the Source of a Pre-Programmed Device
If the Breakout Board has been reprogrammed, the original demo design can be restored. To restore the board to the
factory default, see the
Download Demo Designs
section for details on downloading and reprogramming the device.
