Problem in programming Flash memory of CYIII starter kit.

I wrote a simple logic for cyclone-iii starter kit. I created the NIOS system with on chip RAM and few I/Os. (Here I didn’t include the CFI Flash) SOF download through Quartus II Programmer work...

Hi,

I'm trying something simpler but similar. Obviously I'm a beginner.

I use the Cyclone III starter kit, which comes only with a parallel flash memory, no EPCS.

The question is how to write onto the flash. I read which pin is connected to which pin of the FPGA. I read something about the PFL flash programmer that has to be written onto the FPGA in order to write the programme onto the flash. I used the Altera tutorial to create a PFL-megafunction. My question is now how does everything go together?

The megafunction has variables, which names don't match up with the flash. Additionally I get some "altera_reserved_..." pins in the pin planner that I don't know where to connect to. The length of the variables in the megafunction seem to be wrong (22 address bits but the flash uses 24). I used the correct CFI 128 chip to create the function.

Any suggestion in which direction to head would be greatly appreciated.

Cheers,

Ulle
