programming and turning off board

Altera_Forum · ‎02-21-2009

More newbie questions.

So I have programmed the Cyclone III dev kit board in the first few tutorials.

If I turn off the power of the board, is the program still on board?

If I press the reset config button, is the program still on board?

If I want the board to stop running the program, but I still want the program to reside on board because later I want to use it again, what should I do?

Thank you.

If you programmed it into flash, it will remain on the board after power is removed, and will come up upon power being applied.

You'll need to convert the SOF programmer file to a POF

(File - Convert Programming Files)

Then, you'll need to attach a flash device to your part in the programmer

(right-click on your cyclone III part, attach flash device)

Finally, attach the POF file to the flash device in your programmer and program it.

Mickey, I'll try that.

I found this tutorial... "Using FPGA-Based Parallel Flash Loader with the

Quartus II Software".

Am I looking at the right direction?

I was given this board last week and am now doing independent studying.

So many things to look at that I don't know if I'm looking at the right thing..

Thank you.

Yes, if your board has a parallel flash interface, that app note will work well with it. Which development kit are you using?

Cyclone III development kit. It says in deskription there is 64M Flash memory in the webpage. Does not mention specifically if it is parallel flash interface. Is it?

Thanks.

This one?

I haven't used that one in particular, but it should say in your user guide, check Appendix A.

This one?

Yes, this one has parallel flash, and the user guide (5. Appendix) shows you how to program the flash.

Yes! Thank you. Silly me, it's staring at me right in the face but I just couldn't put my finger on it. I went through the user guide and skipped the appendix because it didn't make sense to me at first.
