By default the heap is declared to be of size 0x2000 bytes and is located in the linker section .heap which is placed in the MEM_L3 memory section.To replace the system heap, an instance of the heap object should be added to the application.

 

For example : To declare a heap of 0xA000 bytes

 

#include <stdint.h>

 

uint8_t __adi_heap_object[0xA000] __attribute__ ((section (".heap")));
