Other Parts Discussed in Thread: CC3200, ENERGIA
Hello! I've created an Arduino / Energia sketch that allows an MSP430 or other compatible target to program firmware to one of TI's Flash-based gas gauges (such as the bq27542). We use it in production on a project that has a CC3200 as the main processor. We upload this sketch, then use it to program the fuel gauge, and then upload our customer firmware. My company has agreed to open-source this project.
Here it is: 
Hopefully this will be useful to others.
Cheers,
Adam J.
