The PCIe solutions board comes pre-programmed with the PCIe Basic demo
bitstream. Other demos included with this kit require that you reprogram the
device with the appropriate bitstream for that particular demo.
That is, each demo, including x1 and x4 variations, has bitstreams that
contain different PCI Subsystem IDs that uniquely identify the demo and
associates it with a particular device driver and demo application. So, if using
the x1 side of the board, ensure that you use the bitstream (or XCF file) with
the x1 identifier in the file name.
Important:
Only connect or disconnect the ispVM download cable from the solutions
board when the power is off. Damage to the devices in the JTAG scan can
occur if the board is turned on. This means that if you have a board installed
in the PC running ispVM, you must shut down the PC before connecting the
cable to the board. It can remain connected thereafter.
To reprogram the solutions board with new bitstream:
1. After ensuring that ispVM has been installed and configured, attach the
2. After the cable has been attached, power on the board.
3. From the Windows Start menu, click Start > Programs > Lattice
4. Click File > Open and navigate to the appropriate XCF file. For the PCIe
programming cable to the board with the power off.
Semiconductor 7.1 > Accessories > ispVM System to open ispVM.
Basic demo, go to the <install_dir>\Demonstration\PCIeBasic\Bitstreams
path to the file PCIeSBx1_ECP2M50_PCIeBasic.xcf.
Note:
Ignore any messages you may encounter about the file being modified.
The date and time of the file may have been changed during installation
and no longer matches the XCF file’s internal date.
