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.
