-* Change the pushbutton switch (S1 - ATMEL reset switch) to a different part.  The current switch has a high failure rate after being washed in the assembly process. (i.e. it does not tolerate the washing process to remove the flux.)

 The Trainer provides an interface the the BeagleBoard's SPI port and the signals are level translated to +3.3V.  The SPI signals are located next to the prototyping area.
