10 years agoFor your information, there is one set of DIP switch (SW6) on Stratix V dev kit related to PCIe and that is to select the lane width.
Ensure you have set the DIP switches to factory default settings. Refer to Figure 4-2 of 'Stratix V GX FPGA Development Kit User Guide' at https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/ug/ug_svgx_fpga_dev_kit.pdf
