Forum Post: RE: Filling up CC2540's memory

Hi Jonathan,

The memory is split into Stack and Heap. The Xdata usage shown in IAR is for the stack.

For the heap

a) dynamically allocated with osal_mem_alloc and

b) statically allocated (global or with keyword static) you'd have to check the usage by

a) setting the preprocessor define "OSALMEM_METRICS=TRUE" in the project options and then putting a watch on the variable memMax, memAlo etc found on lines 181-185 of OSAL_Memory.c. memMax will show you the maximum ever allocated dynamically.

b) checking the .map file output after compiling

Best regards,
Aslak
