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

    Unfortunately i am not using MicroLib. I am using default C library. (no check in Keil Project options for Use MicroLib).

    Currently i can't understand one issue. I have specified the scatter file to the linker. I have

    ARM_LIB_HEAP 0x2007F000 EMPTY  HeapSize { }

    line.

    Nut in .map file i see 

    HEAP 0x20019cc8 Section 3072 startup_efm32gg11b.o(HEAP)
    Heap_Mem 0x20019cc8 Data 3072 startup_efm32gg11b.o(HEAP)

    Why address is 0x20019cc8  and not 0x2007F000 ? I can't understand.
