Rebuilding library after changing hardware design

Altera_Forum · ‎05-05-2006

I am using the standard FPGA design from the Nios II kit and I have a working project with ecos. I want to add another PIO port to my design. After adding the new PIO port in SOPC builder and rebuilding the FPGA design in Quartus, how do I rebuild ecos to give me access to the new PIO port? I tried using the nios2config tool to clean and then rebuild my project, but this did not generate a new copy of install/cyg/hal/system.h in the folders under my ecos project.

I then made a new ecos configuration file in a new folder. When I built that library the system.h file which was generated contained references to the new PIO port I had added. I don't want to have to start a new ecos project every time I tweak my hardware, is there a method to make nios2config regenerate the system.h file after changing the hardware design?

Just delete your folders like this foo_build, foo_install, foo_mlt

and then you should regenerate Bulid Tree

But I think you should try "Generate Bulid Tree" only.

Try it!

Thanks, that worked! Deleting the folders seems to be the secret, regrenerating the build tree does not seem to be enough.
