Very cool, thanks, and few questions.

1. the button should include power button and volume up/down switch, 
should power direct connect to PMU and volume connect to MSP430?

2. Camera is missing, should direct connect to CPU itself :)

3. Any suggestion on FTDI chip's GPIO, I remember there are some 
available could be used.

Allen has question about jtag chain, because we never use this before, 
so his first design might not chained together.
