cyclone III development kit + flash memory

I have purchased the Altera cyclone IIII development kit . I have loaded my design onto the flash memory, so when I power the board the FPGA is configured with my code. Is it possible now to use the remaining space from the flash memory to add user input data. If so how can this be done?

    I imagine it is possible but not easily.

    What about using the In-System Sources and Probes in Quartus? This might be the fastest solution depending on what you are trying to do.

    Cheers

    What you wish to do is very do-able.

    Do you only wish to read the extra data in there, or do ou widh to be able tyo have your design write it, then read it?

    Look as the ASMI MegaWizard for a port that will allow reading / writing into the extra space in the Flash (assuming you are talking about the serial EPCS flash).

    Press on, then advise if you need more help.

    Dear Djoshi,

    1. conversion from .sof to .pof?

    2. 1-bit passive serial?

    3. start address 0x0038'0000?

    4. page_0?

    5. pgm config select rotaty switch on board on position 0?

    Thank you very much for a quick reply!
