Problem with PCIe Root Port on the Altera Cyclone V

Hi guys,

I have problems testing the PCIe Root Port on the Altera Cyclone V Dev Kit. Hope someone has encountered this problem before and have a solution?

I loaded the prebuilt image sd_card_image_cyclone5.bin and followed the steps from the link below, but it failed at "insmod altera_rpde.ko". Has anyone had this issue?

I am using the Altera Cyclone V Dev Kit with a Gigabit Ethernet Controller as called out by the Hardware Requirements.

• Root Port: Cyclone V SoC Development Kit (5CSXFC6)

• Endpoint: Intel® Gigabit CT Desktop Adapter (Intel® 82574L Gigabit Ethernet Controller)

Test Results:

root@cyclone5:/mnt# insmod altera_epde.ko

root@cyclone5:/mnt# insmod altera_rpde.ko

altera-rpde pcie_rpde.1: has no require EP detected

Of course, it failed to run ./dmaxfer:

root@cyclone5:/mnt# ./dmaxfer

EP block fail to open

Fail to get data transfer size

root@cyclone5:/mnt#
