XTCIEVMK2X: In SA SaBasicExample (ARM build version), can we use DDR3 to replace MSMC SRAM in fw_memAllocInit() and fw_memAlloc()?

Hi TI experts,

I am testing SA SaBasicExample (ARM build version). Due to out of MSMC SRAM, I would like to use DDR3 to replace MSMC SRAM in fw_memAllocInit() and fw_memAlloc()? Is it OK? How to do it?

I change MSMC_SRAM_BASE_ADDR to 0xE0000000

if (fw_memAllocInit((uint8_t*)MSMC_SRAM_BASE_ADDR,
                                  MSMC_TEST_PERM_MEM_SZ) == fw_FALSE) {
        printf("ERROR: \"Top Level Test\" fw_memAllocInit failed\n");
        return (-1);
    }

if (fw_memAllocInit((uint8_t*)0xE0000000,
                                  MSMC_TEST_PERM_MEM_SZ) == fw_FALSE) {
        printf("ERROR: \"Top Level Test\" fw_memAllocInit failed\n");
        return (-1);
    }

and set break point in testCommonGetBuffer() in test6.c, then step in the function. Below is the call stack. It still uses MSMC SRAM (addr=0xc040007).
