AIC3204 only receiving if not in debug

I have a program that runs fine under the CCS4 debugger.  When I transfer the program to flash the program does run but it only outputs audio.

It does not process the audio I put into it.

If I hit it with high level audio momentarily it starts to work.

I have added the code from the GEL file to my main.

It is basically the AIC3204 sample program that came with the IDE that I modified.

I am running the main clock at 100 MHz and a sample rate of 16 kHz.

I have tried adding delays at different points in the boot up without success.

Any help would be appreciated.

 

Thanks,

Sam Virgillo

    Problem solved...    Basically the problem was with the configuration of the codec in the sample file I copied (AIC3204).

    The configuration registers for CM routing (1,54 & 1,57) were all wrong.   Not sure why it worked while connected to the debugger.
