Hi,
My program use the FFTC to calculate the 3072-point FFT of 16 buffers in DDR. Those buffers have different values. I pushed 16 descriptors which point to each buffer sucessfully in to the Tx queue. And as expected, i obtain 16 descriptors in the Rx queue, which point to 16 different ouput buffer.
But, all the output buffer contain the same FFT results and the value is just the FFT of my first input buffer. It seems that the FFTC does not update the FFT output and just fill all the output buffer with the FFT result of first input buffer.
So what is the reason for this? Do i set up something wrong for FFTC?
Thanks a lot
