Again, you missed the subject of the thread.

The question was how to update nios ii eclipse project upon on modification in qsys and not to how to create new nios ii eclipse project (that is perfectly described in Nios II Classic Software Developer's Handbook).

From my experience there are 2 cases:

• with minor modifications in qsys

• with major modifications in qsys

With minor modifications (e.g. if there are no changes in qsys instantiation in the top module) it's quite simple: rebuild bsp (with modified .sopcinfo) and rebuild application.

In the 2nd case (e.g. if qsys instantiation should be modified ... and probably also system interface (i.e. external ports)), the better approach is as follows:

1. Qsys: Make modification in qsys and save it under new name

2. Quartus: Instantiate new qsys in the top module (commenting former one), add it to the project and remove former one

3. Quartus: In the top module adjust (if necessary) external ports

4. Quartus: Compile new system and program device with modified .sof

5. Eclipse: generate new bsp

6. Eclipse: in application properties point to the new bsp

This way the old system version is kept and can be easily "reincarnated"
