DSPLIB : DSPF_sp_fftSPxSP usage and issues

Hello Sir,

We are working on dra7xx-evm(AM5777)  EVM with following setup :

1. bios_6_37_03_30

2. xdctools_3_25_06_96

3. CCS5.5

Issue :

We are using DSPLIB call DSPF_sp_fftSPxSP  to perform FFT, but the output of the FFT doesn't seen to be correct.

Please find the attached writeup which details on how the FFT output looks like when we perform it in Scilab and when we use the DSPF_sp_fftSPxSP dsplib call on a SINEWAVE data.

Please verify the same and provide your feedback.

Regards Naveen
