Unable to program Arria 10 FPGA from HPS Linux

[thaler]

I’ve ran into the same problem and found a solution. Maybe this will help you:

Missing /dev/fpga0 device on DE0-nano-SoC

I solved the issue myself. The approach to use Device Trees and programming the FPGA under Linux has changed fundamentally. There is no /dev/fpga0 device anymore. Instead, Linux uses Device Tree Overlays now. See the WS2 Linux Kernel Introdution lab for examples. The Device Tree Overlay as well as the FPGA RBF file have to reside in /lib/firmware. To load the overlay, mount the configfs filesystem and create a new directory in the overlay subfolder: mkdir /config mount -t configfs configfs…
