Honored ContributorI had the same issue with Arria II GX development board and Quartus II 9.1 software. It looks like there is an issue with 9.1 software. Try using 9.0 SP2 it might work. If you want to load a new design try this procedure:
1. Program the FPGA with the PFL program that comes with the dev kit. Since I am using Arria II GX my factory default SOF file is located in C:\altera\90\kits\arriaIIGX_2agx125es_fpga\factory _recovery\build_factory_source\a2gx_pfl_programmin g.sof. I am hoping you will have a similar file for Stratix IV dev kit after you install the kit installation from the following website http://www.altera.com/products/devki...it-siv-gx.html (http://www.altera.com/products/devkits/altera/kit-siv-gx.html). 2. Create the POF file for the flash using Quartus 9.0 SP2, as 9.1 did not work for me. Use the COF in the same directory that is mentioned in step 1 for creating the POF file. Update only the user SOF file and leave the factory default SOF file. 3. Open Quartus programmer. Click the auto detect button which will show the complete chain. Right click on CFI_<SIZE> and change file to the POF that was created in step 2. Program the USER page(in my case it is page 1, and I think it will be the same for you) of the flash only and do a power cycle. You program will be loaded in the user space of the flash. 4. You might need to move some switch in the board to a particular position to load the user code. Refer to the reference manual of the card for more help on the switch. Hope this helps.
