This is a very common error that usually has a very silly cause but can make you loose a lot of time. Here is a short checklist of some possible solutions to the problem. 

Note that this is NOT A COMPLETE LIST!  Feel free to add points if you think it might help 


Qsys and Quartus:

  1. did you run the .tcl script?
  2. reset signals are well connected?
  3. did you set the top-level file in its right-click menu?
  4. when programming the FPGA make sure the selected device is "5CSEMA5F31"

ECLIPSE:

  1. did you recreate the project BSP after modifying the hardware?
  2. did you select the right file to upload? (try right-clicking on the project name and run from the drop-down menu)
  3. are you running the right project corresponding to the programmed softcore?
  4. if nothing worked, did you try restarting Eclipse?

  • Under "Run configurations":

  1. ignore mismatched system ID is checked?
  2. ignore mismatched system timestamp is checked?
  3. did you press "refresh connections" ?


Hope it helps!
