CubeIDE how to set offset for program?

I am making a DFU for stm32f4-discovery board.

My DFU is using a project generated by STM32CubeMX V1.0.

And It worked well with the program generated by the STM32CubeMX V1.0

But when I worked with a project generated by STM32CubeIDE, I cannot make the main program run.

I had made these steps:

First, in system_stm32f4xx.c

#define USER_VECT_TAB_ADDRESS
 
#if defined(USER_VECT_TAB_ADDRESS)
/*!< Uncomment the following line if you need to relocate your vector Table
 in Sram else user remap will be done in Flash. */
/* #define VECT_TAB_SRAM */
#if defined(VECT_TAB_SRAM)
#define VECT_TAB_BASE_ADDRESS SRAM_BASE /*!< Vector Table base address field.
 This value must be a multiple of 0x200. */
#define VECT_TAB_OFFSET 0x00000000U /*!< Vector Table base offset field.
 This value must be a multiple of 0x200. */
#else
#define VECT_TAB_BASE_ADDRESS FLASH_BASE /*!< Vector Table base address field.
 This value must be a multiple of 0x200. */
#define VECT_TAB_OFFSET 0x8000 /*!< Vector Table base offset field.
 This value must be a multiple of 0x200. */
#endif /* VECT_TAB_SRAM */
#endif /* USER_VECT_TAB_ADDRESS */

Seconds, in STM32F407VGTX_FLASH.ld

/* Memories definition */
MEMORY
{
 CCMRAM (xrw) : ORIGIN = 0x10000000, LENGTH = 64K
 RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 128K
 FLASH (rx) : ORIGIN = 0x8008000, LENGTH = 992K
}

Third, in STM32F407VGTX_RAM.ld, I made the same change

/* Memories definition */
MEMORY
{
 CCMRAM (xrw) : ORIGIN = 0x10000000, LENGTH = 64K
 RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 128K
 FLASH (rx) : ORIGIN = 0x8008000, LENGTH = 992K
}
