It seems that with Quartus 9, the programmer doesn't put the software correctly in the EPCS device when used with a Cyclone III, preventing the Nios to boot.

This is not corrected in SP1, but should in SP2. There is a thread on the subject in the Nios forum.

The behavior of this bug is that NiosII on Cyclone III does not boot up from EPCS if you programmed SOF and ELF with v9.0 Flash Programmer.

The workaround:

replace 90\nios2eds\bin\sof2flash.jar with 81\nios2eds\bin\sof2flash.
