Error while compiling hardware design

  1. When I open Qsys, and select the qpf file, see the below error message, I selected another device and reselected the same and was able to get away with error message and able to run Qsys tool.
    Error: ghrd_10as066n2.arria10_hps_0: Unsupported device 10AS066N3F40E2SGE2

  2. Error (12317): QIP file “/home/poonam/a10_soc_devkit_ghrd/ghrd_10as066n2/ghrd_10as066n2.qip” that is being generated from a Qsys file already exists in the project.

I am using 16.0 tool chain build 222 on Ubuntu 12.04. Any idea why the unsupported device error message is for ?
