Troubleshooting
The LatticeXP2 Brevia 2 Evaluation Board is not responsive.
• Verify the LatticeXP2 device is programmed.
The functionality displayed by the board does not match the demo features described.
It is possible the LatticeXP2 Brevia 2 Evaluation Board has been reprogrammed. You can either reprogram the
FPGA with the demonstration bitstream, or read the checksum of the bitstream loaded in the FPGA. To restore the
LatticeXP2 Brevia 2 Evaluation Board to the factory default, see the Download Demo Designs section of this docu-
ment for details on downloading and reprogramming the device.
You can use Diamond Programmer to read the checksum of the bitstream programmed into the FPGA. This value
can be compared against the checksum stored in the JEDEC file. The JEDEC file checksum value is the last line in
the file. This may allow you to determine the contents of the FPGA.
A final option is to use Diamond Programmer to read the current bitstream in the FPGA, and then to reprogram the
FPGA with your desired bitstream.
