Hello,
I am currently working on a DSP based FFT solution using a DM816x EVM. I am using the ARM (runs Linux) to send samples to the DSP (SYS/BIOS) using IPC and syslink and this link works perfectly. Then the FFT operation is performed on the DSP using dsplib v3.1.1 provided by Texas Instruments. I am calling the function DSPF_sp_ifftSPxSP and I have checked the restriction that apply to it (memory allignment, size...). However, the output is all NaN floats.
The DSP part works perfectly baremetal, without the IPC part. So, any idea how IPC could interfer with dsplib?
Thanks in advance,
