All,

I am looking for some assistance in doing a little reconnaissance to 
reverse engineer a segment of an ARM processor board using a very 
proprietary Varicite ARM processor running a Linux Variant. I only need 
to glean some information on the audio portion of the circuitry.  It 
contains a TI 3251 Class D amplifier and some not so sophisticated 
output to a load consisting of several coils. The intent is to determine 
the LC circuit and configuration of the Amplifier to replicate it with 
the load in a different project. The processor and other components 
aren't that interesting.

Any assistance would be appreciated.  I am in the process of getting 
X-Ray photos of the board.  Those should yield some interesting results 
and traces internal to the board.

Any assistance is appreciated,

Robin
