CodeWarrior will not display upper RAM or FLASH memory

[EdProulx]

For no particular reason, CodeWarior will no longer display the upper reaches of RAM or FLASH memory. Anything in RAM above 0x20008000 is not displayed, and anything above 0x40000 in FLASH is not displayed. All that is shown is: BABABABABABA.....

This is on a Frescale processor, the 52258 (512K FLASH, 64K RAM). It might be because the code base has increased and nothing left for CodeWarrior? The system is otherwise behaving correctly, but I cannot debug my application effectively without being able to examine memory.

The same applies to variables.

Check the memory configuration file, 

Project Settings->Debugger->CF Debugger Settings

If "Use Memory Configuration File" is checked than the file specified just below configues how (and if) to access the target for a certain address.
