The reason the firmware needed upgrading is because we have put a beefier MSP micro-controller on the board, subsequently the board layout has changed. Once I got my head around both the motor controllers i2c routines and the old pwm firmware i began merging bits of code together. After a suitable amount of time, anger, coffee, realisation of how stupid i was being and more coffee, I managed to get the new board to seep all the servo pins back and forth, demonstrating that this part of the board works.
Enjoy the video - I did!
Some Photos:
The new servo board. The two LEDs indicate both power supplies are connected. The third LED which isn't illuminated, should be, however due to some primate-like soldering skills, there appears to be a short.
The servos in motion.
The MSP430 programmer. I mounted it on an old credit card to make the wiring a little more secure. Despite it looking horrible, it actually works surprisingly well. Honest.

Good work on getting it going :-)
"Weirdly, adding a static variable into my code (which was only assigned to once) was enough to solve my problem, however this makes no sense why."
This is a well known bug in msp430-gdb. Googling the error spewed by msp430-gdb tells you what to do (searching the mspgcc list using gmane will show you that 10^8 people have seen this before!).

Yeah, it was pretty well documented and once I googled it the answer dropped out pretty quick. Although at first I assumed that I'd done something stupid elsewhere :(.
Glad you got it working - will have to pop round and see it in person sometime :) Gimme a shout when you need another primate for soldering ;)
