Flexbus example fails

I've downloaded an MCUXpresso 2.2 SDK for the TWR-K64F120M. I imported the flexbus driver example and successfully compiled and loaded the code. When I run the code, it prints out: 

FLEXBUS Example.

Initialize FLEXBUS.

Start write/read MRAM.

FLEXBUS (MRAM) test: failed.


I haven't modified any code, so I would expect it to succeed. Has anyone else had this work?


I have the flexbus working correctly on the same board using the KDS3.0 and KSDK1.3.0. I was trying to port this working code to the new MCUXpresso environment and was having issues, so I figured I would build the example to use as a reference. Since the example doesn't work, it doesn't serve as a useful reference.
