TMS320F28069: Can I copy Ram function into ROM before initializing Flash Waitstate and other system initialization?

Part Number: TMS320F28069

Hi,

I need to know  that can I copy RAM function into ROM ( memcpy(&RamfuncsRunStart, &RamfuncsLoadStart, (Uint32)&RamfuncsLoadSize)) before calling InitSysCtrl()? I have seen in example that InitSysCtrl() function call first than memcpy().

I have attached code please check this initialization sequence is right?

int main()
{
 
    memcpy(&RamfuncsRunStart, &RamfuncsLoadStart, (Uint32)&RamfuncsLoadSize);
    
    InitSysCtrl();

    Gpio_select();

    /* Clear all interrupts and initialize PIE vector table:
       Disable CPU interrupts
     */
    DINT;


    /* Initialize PIE control registers to their default state.
       The default state is all PIE interrupts disabled and flags
       are cleared.
     */
    InitPieCtrl();
