FREERTOS heap memory S32k3xx

[manoj_123]

HEAP_SIZE = DEFINED(__heap_size__) ? __heap_size__ : 0x3C00; /*15kb*/

/* heap section */
.heap (NOLOAD):
{
. += ALIGN(4);
_end = .;
end = .;
_heap_start = .;
. += HEAP_SIZE;
_heap_end = .;
} > int_sram

#define configTOTAL_HEAP_SIZE (( size_t ) 1024*8 )

my question is if i try to change configTOTAL_HEAP_SIZE is 10kb or below 15kb its jump to hardfault during runtime but it works perfectly for  configTOTAL_HEAP_SIZE is 8kb how to resolve it

Hi,

could you please specify a device and driver version you are using?
Do you have own example or use a demo one? Any modification you did beside configTOTAL_HEAP_SIZE?
Try to find a function where it goes to fault.

linker file i set
.my_heap (NOLOAD) :
{
*(.my_heap)
}> int_dtcm
__attribute__((section(".my_heap")))uint8_t ucHeap[configTOTAL_HEAP_SIZE];
Memory size

int_dtcm : ORIGIN = 0x20000000, LENGTH = 0x0000F000 /* 60KB */
#define configTOTAL_HEAP_SIZE (( size_t ) 1024*28 )
#define configAPPLICATION_ALLOCATED_HEAP 1

Hard fault is hitting at Clock_Ip_SetFlashWaitStatesCallback()
how can i avoid it
