I have connected the Xilinx Virtex707 FPGA evaluation board to the Jetson TX1 through the PCIe slot.
When the Link speed of the FPGA PCIe block is 2.5 GT/s, everything is OK and the Jetson detects that as PCIe Gen 1.
But when I change the Link speed of the FPGA PCIe block to 5GT/s then Jetson TX1 does not boot and print a non-stop message complaining about pcie interrupt. These are the keywords in the message
“printk message dropped xxx pcie xxx handle_sb_intr xxxx”
only after adding pci=nomsi to the boot arguments, it can boot.
I am wondering how I can resolve this problem.
