cyclone 3 starter kit. permanent configuration rom

Is there a way to permanently program a jic file (or other) to the cyclone 3 starter kit, or does it only use sof files download over the usb/blaster interface? aka It would be nice to be able to do nonvolatile programming so it doesn't have to be tethered :)

    You must program the configuration file into the flash memory.

    This will work provided your sof file is not time limited, namely if you are not using IP cores in OpenCore evaluation mode: without a usb blaster unit attached the unlicensed modules would stop working.

    which file format is that? I have only ever worked with serial Flash for configuration. Do mean use the intel parallel 16Meg flash on the board? I wasn't sure if that's what it was for or not :) . I thought maybe it was just for experimentation. Thanks Cris72

    I presume you have the EP3C25 starter board, which is hardwired for an active parallel configuration (look at MSEL pins). So you can possibly boot from the parallel flash (Intel 64Mbytes?).

    I think you need to program it using the .pof file; anyway you can generate the correct file using the file conversion function available in Quartus.

    I have a different dev board and I always used serial configuration, so I can't help you more than this.

    Hello,

    You can use active parallel flash configuration.

    Check out Appendix A in the starter kit user guide. I'm not allowed to post a link to it directly (due to forum restriction), but Google for "cyclone iii starter kit user guide" and you should find it easily enough.

    It's under altera.com plus the following path....

    /literature/ug/ug_ciii_starter_kit.pdf ;)

    Hope this helps,

    Chris.
