Hello,

I'm trying to implement 'DSPF_sp_fftSPxSP' on OMAP-L138 Experimenter KIT,
Using c674x-dsplib_1_03_00_01.
During the run the program is stuck inside DSPF_sp_fftSPxSP.asm on "SPKERNEL 0,11".
I used DSPF_sp_fftSPxSP(512, source, Twiddle, result, &brev[0], 2, 0, 512);
Brev 64 value array and Twiddle function are taken from "TMS320C67x DSP Library Programmer’s Reference Guide (SPRU657C).

I wonder what could make the fft function be stuck?

Thanks,
Jacob.

    SOLVED!
    I used a variable N for 512. I accidently declaired N as uint8.
    Sorry for unnecessary thread.

    Jacob.
