Hi


After checking, it seems this is not officially tested for the Cyclone5.


However we could try to get it to work on your end.

The problem could be you not setting the Cyclone5 to have partial reconfiguration?

The configuration during the linux should only be on the FPGA fabric and not reconfigure the HPS.

You could not reconfigure the HPS when running in linux.
