Newbie Question

Hello people,

I have a problem, I know it may seem basic but we all have to start somewhere. Cant get the HW design to work with the SW. I have generated a small system in SOPC builder and compiled it in Quartus. I am now trying to download a CORDIC programme on to the Nios II using the NiosII IDE.

How do I use the address of the memory in the IDE programme that is created when SOPC has finished. Do I need to include the .ptf file that is generated? If so how do I do this. Or is it something to do with the system.h file, this is supposed to be generated by the SOPC builder also, no? I cannot find this system.h file at all.

Any help would be greatly appreciated.

Thanks,

    The system.h is the interface between the SOPC System and your Nios Projects. In that you find the address of your components "suffixed" by &#39;_BASE&#39;. You can find this project in the Nios Project Directory after build it.

    Thanks for the reply.

    I did build my project in the Nios IDE and also I have generated the system in SOPC and compiled it in Quartus but it still did not produce the system.h file. Any thoughts on why it would be doing this.

    The system.h file resides in the System Library project associated with your user project. It will exist in a path like so: 

    <syslib>//system_description/system.h

    A Nios II C/C++ application will not build without this, so it would be difficult (impossible?) to create such a project without one.

    Have you ever tried to clean your Nios Project and rebulid it? it can works. When you clean (option Clean...) a project all the files created in the build process are deleted (but the files created for you remain in the directory). Watch the terminator Nios II IDE window when a project is being bulding; the message "Generating system.h ..." normaly appears when you are buliding a project for the first time and when you alter some System Properties.

    I hope I am not being redundant.

    Regards.
