TDA4VM: Where do it allocate from when using c++ new operator?

Part Number: TDA4VM
Other Parts Discussed in Thread: SYSBIOS

Hi experts,

I'm working on psdk7.00 version. I want to use c++ new operator in rtos, but the new operator seems not allocate memory from DDR_MCUx_x_LOCAL_HEAP. So could you kindly tell me where do the new operator allocate memory from? And, is the c api malloc allocate from same place ? Is there a way redirect it to DDR_MCUx_x_LOCAL_HEAP?

Below is the link.cmd file of mcu3_1

/* linker options */
--fill_value=0
--stack_size=0x2000
--heap_size=0x1000

#define ATCM_START 0x00000000

-e __VECS_ENTRY_POINT
