How Import project nios 9.1 from 7.2

FPGA Project :

Start Quartus, open the fpga project (*.QPF) agree to upgrade from previous 7.2 version to newer version 9.1

start sopc builder ( from menue -> tools -> sopc builder)

you will see a dialog that tells to what component are upgrade from ??? existing version to the new version. if components are not found ... you need to add them (mostly custom components)

Re-Generate the sopc builder design, if finished without error, exit sopc build

now recompile the complete fpga project ... (and wait a while :-) )

now your fpga project is uptodate and upgraden from old ptf to the new sopcinfo file

start the ide

you must import both project folders (hello_world_0 and hello_world_0_syslib) one after another, the is an ide menue entry for importing, just try it, can't tell you right of my head which one is the correct one.

now recompile and that should be it.
