Hi All,

We are developing basic analog phone using TMS320C54CST and
MSM7716 as codec.

Codec is going to be connected at McBSP0 for audio data and
McBSP1 configured thru SPI for control data.

I need to know how we can configure the McBSP for our codec
(MSM7716), we have tried to configure but looks like its not working
for us.

So any suggession how to do this or any basic source code to
configure McBSP and read write will be great help as we are at
critical stage of the project.

I am also not sure whether the McBSP setting will depend upon
codec we use, as I am new to DSP so plz bare with my stupid question..
Thanks,

Manish
