C2H hardware acceleration tutorial problem

Altera_Forum · ‎11-29-2009

Hello, I'm attempting to run the c2h FFT hardware acceleration tutorial as described in: http://www.altera.com/literature/tt/tt_nios2_c2h_accelerating_tutorial.pdf

Upon building the project I get the following error message:

Severity and Description Path Resource Location Creation Time Id

C2H C2H ERROR: connect_variable pragma for accelerator_optimized_fft/BufferedRealCalcDataRead specified module BufferRAM1, which does not exist. at file: , line: c2h_fft line 0 1259519543367 136

Since the description tells me that the error occurs at line 0, I cleaned the project, which didn't fix the error.

I've followed the tutorial precisely, and properly named the BufferRAM1, but still the same error message.

Can anyone give me some insight?

Thanks in advance.
