pof file size and address in flash

[dvirbuc]

hello

I am trying to determine the beginning address and finale address of the pof in the flash

1.  how can I know where the pof file is stored in the flash,
   is it different for every FPGA?
2. how can i know the size of the pof file stored in the flash?

After I finish a full design compilation and generating the .sof/.pof/.jic files, I am left with a file DESIGN.map.

It's contents are (this is from a 13.0sp1 CycloneII compile):

BLOCK		START ADDRESS		END ADDRESS
Page_0		0x00000000	        0x00076CA1

Notes:
- Data checksum for this conversion is 0x00D518FB
- All the addresses in this file are byte addresses

Which shows that the data starts at 0x0 in the config prom and is length is 0x76CA2 bytes.

Hi,

Welcome to Intel's Forum.

You may check the DESIGN.map file to check the .pof file stored and the information of the addresses.

All the addresses in this file are byte addresses.

You may also refer to the community's comment below to locate the address information.

Thank you and hope to hear on your findings.

Kelly

thanks for the reply.

I can't find the DESIGN.map file... where it is stored?

(I'm using Quartus Prime Version 20.1.1 Build 720 11/11//2020 SJ Standard Edition

It is stored in your design's place and route directory, along with all your other generated files.

And replace the letters DESIGN with your design's name. Or look for a file with the .map extension in your project directory.

I searched in the directory \..\my_project\output_files (where the .sof\.pof file are stored) , and there are no files with .map extension... there are: my_design.map.rpt, my_design.map.summary, and they are the Analysis & Synthesis report.

I also checked in the db directory and incremental_db directory.

maybe I need to toggle an option somewhere?

And replace the letters DESIGN with your design's name.

Of course

Hi，

Could you try to just click on your design file, and don't go into the output files directory. It should be available once you click on your design file. and you will see a .map file. You can open it with notepad/notepad++ and scroll down to the Memory configuration to check the address in flash.

I will attach some screenshots on the file location and the memory configuration that contains information of the flash.

Thank you.

Hi,

Kindly find the screenshot of the .map file location here after you click on your design file(mine is hello_world2nd)

Once you open the file with notepad/notepad++, you may search for the memory configurations part to check out the information needed, and a screenshot of how the memory configurations look like:

Hope you manage to find these files and clear your doubts.

Thank you.

Sorry, but I still can't find the design.map file.

What do you mean by

Could you try to just click on your design file

In my project directory I have only this files:

do I need to search in another directory? I have also searched in the Quartos directory.

Can I view the .map file from quartus itself? 

thanks

[ak6dn]

What about in the output_files directory? Is that where you have Quartus place your generated files?

[dvirbuc]

as I said earlier:

I searched in the directory \..\my_project\output_files (where the .sof\.pof file are stored) , and there are no files with .map extension... there are: my_design.map.rpt, my_design.map.summary, and they are the Analysis & Synthesis report.

Hi,

With the output files generated from the screenshot, the .map files is not present as your compilation was not on the NIOS II Eclipse side, but only on Quartus prime.

Maybe you could try compiling your project on NIOS II Eclipse to see whether the .map file is auto generated.

Hope to hear on your findings.

Thank you.

Kelly

This OP's issue has nothing to do with NIOS II Eclipse, it is related to Quartus generating a config PROM image.

When Quartus generates such an FPGA image for a config PROM it should also generate a .map file showing the PROM layout.

[KellyJialin_Goh]

Hi,

The .map file is not present as your project did not generate your pof file for EPC4, EPC8, or EPC16 flash configuration device to store the byte address. Therefore you will not be able to see the stored byte address or the size of your .pof file and no .map is auto generated.

Hope this clarifies your doubts.

Thank you.

Can I generate .map file myself?

Can I obtain the memory address and size in any other way?

Because the programmer tool need to know the address and size of the pof file I assume it is stored somewhere or am I wrong?

[KellyJialin_Goh]

Hi,

I have found a similar community thread where you should be able to determine the pof file size with the link here:

https://community.intel.com/t5/Programmable-Devices/How-do-I-determine-FPGA-image-size-within-a-POF/td-p/146478

Hope this clarifies your doubts.

Thank you.

Thanks. It helped a bit.

But I still don't know where  in the flash the pof is stored.

And in my pof file the last section does not have Page_0 but has:

bICB 00000000 00010000;

mCFM0 00072000 00780000;

tUFM 00002000 00380000;

thanks

Hi,

When you are converting your .sof file to a .pof file, you must have chosen your configuration device, which is ready to store your .pof file there. There is no text file/ information showing the stored location as you have already chosen when you are converting. Here is a link for your reference on procedure of converting your .sof to .pof and the targeted flash devices: https://www.intel.com/content/www/us/en/docs/programmable/683698/21-1-19-1-0/converting-sof-files-to-a-pof.html

Hope this could help.

Thank you.

I didn't use this tool. Quartos generated a .pof file automatically.

If so, how the programer tool know where to store the pof file in the flash. 

thanks

Hi,

In your case the address in flash is 0x0 which is where it is stored. You may refer to this link for additional information :https://www.intel.com/content/www/us/en/docs/programmable/683698/21-1-19-1-0/implementing-page-in-the-flash-pof.html

Hope this clarifies your doubts.

Thank you.
