Error (174068): Output buffer atom "soc_system:soc_inst|soc_system

Hi,

I have built up an FPGA system in Qsys starting with the GHRD reference design and adding components. I actually built a simialr system for an Arria V Dev Board and that worked fine. Now when compileing in Quartus after a succesful generate in Qsys I get 100's of error messages like this one:

Error (174068): Output buffer atom "soc_system:soc_inst|soc_system_hps_0:hps_0|soc_system_hps_0_hps_io:hps_io|soc_system_hps_0_hps_io_border:border|hps_sdram:hps_sdram_inst|hps_sdram_p0:p0|hps_sdram_p0_acv_hard_memphy:umemphy|hps_sdram_p0_acv_hard_io_pads:uio_pads|hps_sdram_p0_altdqdqs:dq_ddio[0].ubidir_dq_dqs|altdq_dqs2_acv_connect_to_hard_phy_cyclonev:altdq_dqs2_inst|extra_output_pad_gen[0].obuf_1" has port "SERIESTERMINATIONCONTROL[0]" connected, but does not use calibrated on-chip termination

The rest of the errors are in the attached file joe.txt

Any suggestions?

Thanks Martin

      I came here loooking for a solution, but I founded what I was doing wrong.

      After the first compilation, when the fitter fails, you must run the following TCL scripts:

      hps_sdram_p0_parameters.tcl

      hps_sdram_p0_pin_assignments.tcl
