LatticeECP2M PCI Express Development Kit User’s Guide
Troubleshooting
This appendix outlines some debug procedures to follow when experiencing
trouble installing or running a demo on a Windows PC.
Troubleshooting Demo Software Installation
Troubleshooting the Solutions Board
The most likely installation issue that may arise for the kit demo software
will be related to permissions. Depending upon the system security
policies, you may need to have Administrator privileges to install into
certain directories, for example, the Program Files directory in Windows.
Ensure the board is installed into a PCI Express slot. The board only fits
physically into a PCI slot. The board or PC can be damaged if power is
applied when you attempt to fit the board into the wrong type of slot.
Ensure the board has a valid PCI Express bitstream loaded in the SPI
flash and for LatticeECP2M that the Mode DIP switches are set to
program from SPI flash.
Ensure the four Status LEDs are on, indicating the board is seen as a PCI
Express endpoint. If the two yellow LEDs and two green LEDs are not on,
the board is not being recognized by the PC BIOS or Windows. You can
try installing in a different PCI Express slot to see if that fixes the link-up
problem. You can also try pressing the solutions board’s reset button
immediately after the PC boots.
Ensure the board is seen by Windows. From the Windows desktop, right-
click on the My Computer icon and choose Properties. Then, select the
Hardware tab and click the Device Manager button. Note that this may
vary on other operating systems. In the Device Manager dialog, verify that
the LSC_PCIe driver and solutions board are shown in the list.
