    Hi Jeff,

     I think you run out of the stack with the fft function Try to increase the stack size. You should be to use the TI-RTOS ROV to find out the status of the stack - how much was allocated/used, etc. Below in the highlighted field in yellow is where you can change the Hwi stack size.
