FFT C2H tutorial Not Working

For the accelerator optimized FFT, I get the result as below: -

nios2-terminal: connected to hardware target using JTAG UART on cable

nios2-terminal: "USB-Blaster [USB-0]", device 1, instance 0

nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate)

FFT Benchmark Starting (this will take up to 20 seconds)

- Running 1000 iterations for both software and hardware.

- Each iteration runs a 256 point radix 2 FFT transformation.

The software only output data is correct

The hardware accelerated output data is correct

nios2-terminal: exiting due to ^D on remote

you may clean the project and rebuild again.

By the way, the definitions for the accelerator optimized FFT I build is as below: -

#define BufferRAM1 (alt_16 *)0x0000

#define BufferRAM2 (alt_16 *)0x0200

#define BufferRAM3 (alt_16 *)0x0400

#define BufferRAM4 (alt_16 *)0x0600

#define CosRAM (alt_16 *)0x0800

#define SinRAM (alt_16 *)0x0A00
