RAM Memory Utilization

I am working with TWR-K60D100M.


Stack Size I have used for Tasks is 21KB (Calculated from TASK_TEMPLATE_STRUCT, also seen from MQX Stack Usage).

Main Application BSS RAM is 34KB (seen from .MAP file).  So total RAM used is 55KB approx.


I declared some more variables then build the project and Study  .MAP file, that indicates Main Application BSS RAM is 62KB...And if I load that project it is stuck !!


From TWR-K60D100M User Manual I come to know that RAM Size is 128KB. Then why this is happening?


Is K60 RAM is divided under SRAM_L and SRAM_U of 64KB ? If yes then how can I access both RAM segments ? What changes I have to made in Linker File....?


Why I am not able to utilize 128KB of RAM?
