ADAU1452 Wavplayer

And when I was developing ADAU1452,  I encountered a problem,  I use the WavPlayer to play  sound data  in external Flash,

  I chose to play in a loop, but after 30 minutes,  the DSP stop playing. I don't know what caused it?

  Does the WavPlayer always play when chose "Loopback"  , or there is a limit  times?

the configuration of the WavPlayer is as follows:

the Sigma project of ADAU1452 is as follows:

    Hello,

    I have tried to reproduce this on my end, but the WAV player is working properly for me. There is no provision in the code for a maximum number of loops. If "Loopback" is checked, the DSP is supposed to keep playing back forever.

    Some ideas - is it possible the DSP itself was somehow reset after the 30min? Could there be another device attempting to access the memory?

    I can't imagine there is something in your audio file causing this, but if you'd like to attach the project and your WAV file, I'll try them on my eval board here.

    Regards,
