Other Parts Discussed in Thread: OMAP-L137

I modified the audio example in PSPDrivers and debug it on OMAP-L137 EVM, I found that some variables (i, j) had wrong value and it no work - no audio.

I've added my project as attachment. I am really waiting for an answer, I tried everything, but I couldn't find anything wrong.

5734.AudioFilter.rar

Could you help me, please?

Best Regards,

    The functions in the C64x+ DSPLIB will work on the OMAP-L137 C674x core. You should make sure the C674x DSPLIB is listed first so that any functions that are implemented in both libraries will be taken from the C674x DSPLIB and not from the C64x+ DSPLIB.

    Did you get the audio example to work before modifying it? If not, please go through that example and get it working.

    Start with the working example and put in your modifications slowly, confirming the operation with each change until you get to the fully modified version that you want to have.
