RM44L520: Data Abort after setting

Hi Andrew,

Please take a look at my app note here:

http://software-dl.ti.com/hercules/hercules_docs/latest/hercules/FAQ/FAQ.html#troubleshooting-abort-exceptions

Check the value of C15 DFSR Register, address register, and MCU general register R14_abt?

CP15 DFSR = 0x80D 

Which seems to correspond to an abort caused by lack of permission for a write operation. 

CP15 Data Fault Address = 0x23B98

R14 = 1D4E4

I have already increased the task privilege level and disabled the MPU on all cores so I'm not sure what other permission issue I could be having. 

 The memory location you read was not programmed. The unprogrammed memory location doesn't have valid ECC value, so reading unprogrammed address will generate uncorrectable ECC error, then data abort.

I not quite sure how I should go about resolving this. The auto generated linker file that is generated doesn't seem to reference that portion of memory either. 

Please double check if your code tris to read the data at 0x23B98. What happens if the RAM ECC is disabled?
