Use of SRAM beyond 64K for K60 controller with MQX RTOS-RTCS using CodeWarrior

Hi Friends,


We are developing an application using K60 micro controller (128KB internal SRAM) with use of MQX RTOS and RTCS. CodeWarrior's Basic suit with MQX 4.1.0 is used for software development.


Till date, SRAM memory requirement of our system was less than 64KB and every things are working OK.


But during our application expansion phase, we need more SRAM (total RAM around 85KB) to accommodate additional variables. On project compilation, there is no error and seen that memory map is OK. But when we run this application, program hangs out.


Is this because of RAM requirement for MQX RTOS-RTCS components ? If yes, then is there any way out to get more memory ?


How to know that what amount of memory is taken away by MQX components ?


Is there any option to be defined in the code warrior environment to set MQX memory in the upper RAM area ?
