Hello,
I have a LOGICPD Zoom OMAP L138 eXperimenter kit, And I have made a simple loop-back between the Audio Codec and the ARM coreit's working quite well, the sound is not to noisy, and when I generate a sinusoidal I get a sinusoidal on the output of the board, but when I read data from my buffer it seams that sometimes the bit of sign is not correctly read by the ARM core from the bus. (as you can see in the graph below)
As long as I don't want to modify data, there is no problems, I have a clear sinus on the output of the board but I want to compute the average of two sample and replace the sample in the middle by this computed value I have a big spike on the output.
Did anyone have an idea of why I have this strange data in my buffer ?
Thank you in advance for any help you can provide me.
