LAUNCHXL-F280025C: I can't upload the code I did to a flash memory

Hi,

I have a LAUNCHXL-F280025C card. I'm just learning the development I have written a sample code and ran it in RAM, everything is fine.

But I want to load the code to flash and I was not successful. I found a code like below but it didn't work. How can I boot using flash.c and flash.h libraries?

If there is a short code, please help me.
My goal is just to make the whole code work with FLASH and not in RAM.
Thank you for your interest in advance.

the code I found but could not run:

//  memcpy(&RamfuncsRunStart, &RamfuncsLoadStart, (size_t)&RamfuncsLoadSize); // Flash -> RAM
//  InitFlash();

// INCLUDED FILES
#include "driverlib.h"
#include "device.h"
#include "board.h"
#include "c2000ware_libraries.h"

void init_setup_GPIO();
void init_signal_tester();
void init_signals_and_comparator();

// Here my variables are defined

// Main

void main(void)
{

    //  !! I need help on what to write here for the flash process !!


    // Initialize device clock and peripherals
    //
    Device_init();

    //
    // Disable pin locks and enable internal pull-ups.
    //
    Device_initGPIO();


    //
    // Initialize PIE and clear PIE registers. Disables CPU interrupts.
    //
    Interrupt_initModule();

    //
    // Initialize the PIE vector table with pointers to the shell Interrupt
    // Service Routines (ISR).
    //
    Interrupt_initVectorTable();

    //

    Board_init();

    //

    //
    C2000Ware_libraries_init();

    //
    // Enable Global Interrupt (INTM) and real time interrupt (DBGM)
    //
    EINT;
    ERTM;


    while ( (GPIO_readPin(start_button)) == 0 )
    {

        // SINYAL GIRISI BEKLENIYOR
    }

    while ( (GPIO_readPin(start_button)) == 1 )
    {
        // TEST KODU BASLIYOR

    init_setup_GPIO();
    init_signals_and_comparator();


    //DEVICE_DELAY_US(250);
    }
