Nios II Gen2 - Tethered Design - Can't go back to untethered
Just a note to people thinking of trying the NIOS II Gen2 processor.
We have a license for NIOS II but that doesn't license NIOS II Gen2, at least not the preview version anyway. Also after removing the NIOS II Gen2 processor from QSys for the above reason the design still wouldn't compile as before - it always resulted in producing a time limited sof (a tethered design). Luckily I had a backup from yesterday! I didn't have time to find out what went wrong in detail - but do be warned!
