How to initialize MPC5643L (TRK-USB-MPC5643L) and run simple application

I am having a hard time getting the TRK-USB-MPC5643 evaluation board to run code out of the box. I have been able to get the example code provided in "MPC5643L-TSENS-Temperature_calc-v0_1-CW29" to build and "run" on the target using CodeWarrior Development Studio 10.7 (Eclipse), however before the program never hits the main entry point of the program and the processor gets stuck at IVORltrap (Machine Check / NMI interrupt handler).

 

I figure there must be something wrong in the way that the processor is being setup causing it to jump to an fault interrupt routine that does nothing.

 

Any pointers would be helpful.

 

Thanks.
