I believe the only configuration difference is no data flash but a bigger  
code flash.

I bet that SP (or maybe PC) gets set to an unwanted address causing a bus  
error. I had this happening to me with the m5475evb. Try editing your  
linker script and change the stack to something less than max.

Good luck,
