Hi,


Let me suggest this,

  • it could be a problem with the FPGA not being configured before the host system starts to enumerate the PCIe. To test this theory, you could bring the system up, program the FPGA, then reboot the system without cycling power (Ctrl-Alt-Del on Windows machines).
  • Or you could externally power the dev board, configure the FPGA, then power up the system.
  • In either case, if the system then sees the card, you know it's just the configuration time.
  • If it still doesn't work, I would then hook up the Signaltap with the LTSSM as described in the Debugging section of the user guide.


Looking forward to hear back from you.
