FFT of C28x - caitantan - May 7 7:03:25 2008



Hi=A3=ACeveryone=A3=ACI am a new member of DSP group. I am trying to do FFT=
=20
using TMS 32028335 kit. I use the fft library that TI provided.=20
Everytime I tried to build the build.pjt in the fft library, the CCS=20
will say an error as below:
"[Linking...] "C:\CCStudio_v3.3\C2000\cgtools\bin\cl2000" -
@"Debug.lkf"
<Linking>
>>   error: linking files with incompatible memory models (file
            'C:\\tidcs\\c28
\\dsp_tbox\\fft\\cstb\\fft512c\\build\\Debug\\fftcd.obj')"

If I try to directly load the build.out file in the debug folder to=20
the target board,the CCS will come out an error says:=20
"Data verification failed at address 0x3FFFC0.
Please verify target memory and memory type."

I don't know how to figure out this problem and have no idea of how=20
to put the data that I wanna process into this code to do FFT.

Any help is much appreciated!
Thanks!

Best Regards!
