    We were able to restore the JTAG chain by switching SW8.2, which disables the FPGA on the JTAG chain. Once we do that, we were able to restore the max10 device using the factory recovery steps as described in the files that came with the board.

Does it work if you use the factory_recovery/fpga_recovery/AVSTX8.pof for you dev kit? If it works with the recovery pof then it might be that your pof build have some issues. Does it also happen if you load the sof you used to create the pof? There's also a PCIe reference design in examples/pcie_ed/pcie_ed/output_files/convert-to-pof/output_file.pof which you might try.
