Process for Embedding NIOS Code in .pof

Hi,

if you would like to have your Nios code in the programming file, you have to have a on chip rom (maybe a ram will work, too) and you have to check the "Enable non-default initialization file" option in your SOPC on chip rom module.

You have to make sure that the Nios II IDE creates a *.hex file named according to the field "User-created initialization file". If all your settings in SOPC are okay (reset vector, etc.) then it should work after you re-generated your SOPC system and recompiled your Quartus project.

After recompilation of your Quartus project, the Nios program should be also in your *.sof file.

The basic steps are as follows:

1. Build your SOPC sytsem with onchip ROM and enable the "Enable non-default initialization file" option.

2. Generate your SOPC system.

3. Create a Nios II IDE project based on the just generated SOPC system.

4. Build your Nios II IDE project and make sure that the *.hex file according to your "User-created initialization file"-name was created.

5. Go back to SOPC and regenerate the system that now includes your *.hex.

6. Implement your SOPC sytsem in a Quartus project and compile this to get your *.sof and *.pof files.

This is the way I do it.
