How to generate the flash.pof file in PFL?

I am trying to implement PFL IP in my project. I am using a CPLD to configure FPGA using 128Mb flash . For this I first have the CPLD code compiled. This generated a CPLD.pof file. After this I instantiated the PFL IP and generated the QIP and SIP files. In Intel FPGA Parallel Flash Loader User Guide, it says Compile and generate a pof for the flash memory device. My question is how do I do this?

Can I only compile the QIP?

Thank you in advance.

Hi,

Programming of the flash device can be done by two methods refer the below application note,

https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/an/an478.pdf

 

Let me know if this has helped resolve the issue you are facing or if you need any further assistance.

ErrorCapture.PNGHi Vicky,

Thank you for your reply. I followed the AN478 as well as AN386. I tried everything.

1 ) I instantiated the PFL in my CPLD code and compiled it . This generated a new CPLD.pof. I thought this is not the Flash.pof. So I tried the following:

2) I made a separate project with only the Flash and used the PFL IP . I then compiled this flash project which generated the Flash.pof.

I added this QIP and SIP ( for the Flash) to my CPLD code . then I went to the programmer window and added the CPLD.pof. When I attach the flash device and try to change the file for the flash,

It throws in an error " Only Flash memory programmer object file is supported". I am attaching the screenshot of my Programmer window.

Can you please suggest what wrong am I doing?

Also can you tell me if I am doing right by having a separate flash project or shall I instantiate the flash in the CPLD ? I have tried the second option but that doesn't generate the flash.pof only.

Thank you.

Hi Vicky,

My quartus II was corrupt. So the device selection was getting messed up everytime I was generating the sof file for the flash and so the corresponding pof file was messed up too. I installed everything again and now the device selection doesn't change . I am able to generate the pof file and the programmer doesn't thrown in any error.

Thank you once again.
