Missing component in system.h

Hi,

The problem I have, is a missing component in the system.h file. I added a dual-clock on-chip memory in my SOPC-Builder system, which shall be written by a DMA and read by the Nios II processor. the On-chip memory is named fft_buffer. This name also appears in the ptf-file created by the SOPC-builder, but I re-compile my software project, the fft_buffer does not appear in the system.h file.

Has anybody an idea, what could be the reason for this or what can I do to solve this problem?

    Are you sure your system library is pointing to the right PTF file? Did you make a copy of the project or something akin to that? Also, are you sure you've got the NIOS connected to the FIFO?

    Good ideas!

    I verified that I use the rigth PTF. The OC-Memory is connected to Nios II data master. I did not make a copy of the project.

    Any other idea?

    can you post a copy of your PTF file and the".v" or ".vhd" file that accompanies it?
