quartus 9.1 and nios 7.2

okay the fpga image is done with quartus 9.1 but why don't you do your application with nios ide 9.1 as well ?

if i am right, up to quartus 7.2 the sopc builder created *.ptf files that decribed the sopc nios design and starting with that version the *.sopcinfo file was introduced as well as *.tcl instead of *.ptf for ip's. so ptf is depricated.

so if your design is done in the current quartus 9.1 i am quite unshure if the old ptf is updated / created as well or if you need to explicitly tell the sopc builder to generate these files. nios 7.2 is based on ptf if i am right (too long ago, too many versions since then :-) )

sorry i can't help you more with the ide as i am more working with the hardware. but as far as i remember you can create new ide projects or import existings projects. you need to point the ide to your ptf that describes your sopc project and then you can select for example the hello world and choose the smal version. i remember that was quite easy to do.
