I can’t seem to trigger any activity or responses from the expansion board when connected to our HiFive development board (running linux from Feedom U SDK dir.). Pretty much followed the startup guide (HiFive Unleashed Expansion Kit: Quickstart Guide (loaded the bitstream onto board via Polarfire)).
Tried putting a RAID controller on the PCIe x16 to trigger some sort of action. But it didn’t really make a difference (tried command lspci and checked the /sys/bus/pci/… directory too. but it was empty). Nothing is connected to the RAID controller, but I think it should still work for testing purposes.
I’m not sure if the quickstart guide is missing any information on getting the development board to work with the expansion board, does anyone have any information regarding the setup that I could be missing? It basically runs like the expansion board isn’t even there.
