The first step is to program the FPGA and power on the system such that the PCIe link is detected by the Host system. This can be accomplished by either:
• programming the design file into the flash present on the FPGA board, or
• programming the device directly via JTAG.
If the card is powered by the Host PC, it will need to be powered on to perform this programming using JTAG and then re-started to allow the PCIe link to enumerate. After the system is up and running, you can use the Linux lspci utility to list out the details for the FPGA-based PCIe device.
