Problems with kernel >= 4.x

Hi,

I currently trying to replace my kernel with version 3.17 with a newer

one with version greater than 4.x.

I tried several versions but I am facing some problems and maybe anybody

else had the same issues and know a fix.

1. Problem

The bridges are renamed from hps2fpga to br0 and so on. I am using the

standard sockit device tree for the Terasic DE1SoC.

Is this common that the old names are gone? And are the bridges now

enabled and disabled automatically?

2. Problem

I cannot configure the fpga by writing the rbf file to the /dev/fpga0 device.# cat /sys/class/fpga_manager/fpga0/state

power off

It looks like the FPGA is not powered?!

Big thx in advance
