Hello
Memory areas (segments) defined in the PRM file should not overlap.
Here I assume your objects are allocated in EEPROM_14 and nothing comes into TestMemory.
This is the reason you cannot retrieve its start/end address.
Also for HCS12X it is not recommended to defined memory area going across several banks.
I am not sure to understand what you are trying to achieve here, but if the purpose is to test memory on several pages I would rather recommend you to proceed page after page.
HCS12X is a banked architecture after all.
You can decide to go with global addresses, but then also, make sure you do not define a segment (memory area) across a 64K global page boundary.
