How to debug through malloc function?

zulu nation

Hi All,

I am using EFM32GG11 cpu and have problem with malloc function. It crashes on the first call.

I have specified stack and heap areas in the scatter file.

I would like to debug through malloc function. I am using the standart C library linked to my keil MDK 5 project,

How could i build c runtime and link it to my project?

Thanks,

Parents

    The Heap/Stack are more usually defined in startup.s

    ;*******************************************************************************
;
; Amount of memory (in bytes) allocated for Stack
; Tailor this value to your application needs
; <h> Stack Configuration
;   <o> Stack Size (in Bytes) <0x0-0xFFFFFFFF:8>
; </h>

Stack_Size      EQU     0x0800

                AREA    STACK, NOINIT, READWRITE, ALIGN=3
Stack_Mem       SPACE   Stack_Size
__initial_sp


; <h> Heap Configuration
;   <o>  Heap Size (in Bytes) <0x0-0xFFFFFFFF:8>
; </h>

Heap_Size       EQU     0x2000

                AREA    HEAP, NOINIT, READWRITE, ALIGN=3
__heap_base
Heap_Mem        SPACE   Heap_Size
__heap_limit
