Thank you very much for the insight! I had some large statically allocated global variables that I had brought in from other code. Once I made them a lot smaller my code to initialize peripherals and ring buffer worked.
Although in the code you posted, I believe that the vPortFree() needs to be after the call to prvSendMessageToGGC() because I think xHostAddressData is using memory that gets freed otherwise.I was getting errors like this:
