Can not jump to APP from bootloader on STM32G0B0CET6

[sg0993]

Hi I have a question that blocked me for several days, Hopefully someone can help, thanks a lot.

1:MCU:STM32G0B0CET6,Develop tool:STM32CubeIDE

2:I wanna have a test for OTA ,so i create a bootloader project and app project

3:Flash segmentation:

1)Bootloader(32KB),0x08000000~0x08007FFF

    APP(240K):0x08008000~0x08047FFF

    APP BAK(236K):0x08048000~0x08079FFF

   INFO(8K):0x0807A000~x0807FFFF

4:In Bootloader ,try to jump to APP(0x08008000):

5:Attached the source code (bootloader and app) and hex file(in debug directory)

6:Modifed "ld" file in bootloader project and app project, and I confirm  the stack address in 0x08008000 and reset_handler in 0x08008004 is correct.

And have set vector in main entry(first line in main()):SCB->VTOR = FLASH_BASE | 0x8000;

7:If i use stm32CubeProgrammmer and STM32CubeIDE to start ,app will be run ,But app can not run via bootloader software jump.

bootloader jump slide:

void RunUserCode( void )
{
    uint32_t* ucaddr;

   // if( ( ( *( uint32_t* )ROM_APP_VECT_START_ADDR ) & 0x2FFC0000 ) == 0x20000000 )
    if( ( *( uint32_t* )APP1ADDR ) == 0x20023FF8)
    {
       	HAL_DeInit();//DeInit The Peripherals Used By The Bootloader
        //Rocky report fault shield first __set_FAULTMASK( 1 );
        __disable_irq();
        __set_MSP( *( __IO uint32_t* )APP1ADDR ); // Get top of stack address and initialize SP
        __set_PSP( *( __IO uint32_t* )APP1ADDR );
        __set_CONTROL( 0 );
        ucaddr = ( uint32_t* )( ROM_APP_VECT_RESET_ADDR ); // Get APP Reset Handler address
        ( *( ( void( * )( void ) )( *ucaddr ) ) )();    // Let's Jump!
    }
}

 app vector set:

int main(void)
{

  /* USER CODE BEGIN 1 */
	/* 第一步：强制设置向量表偏移，优先级最高 */
  //SCB->VTOR = 0x08008000;  // 必须放在最前面！
  SCB->VTOR = FLASH_BASE | 0x8000; 
   setMainState(BOOT,3);
  /* USER CODE END 1 */

  /* MCU Configuration--------------------------------------------------------*/

  /* Reset of all peripherals, Initializes the Flash interface and the Systick. */
  HAL_Init();

  /* USER CODE BEGIN Init */

  /* USER CODE END Init */

  /* Configure the system clock */
  SystemClock_Config();

  /* USER CODE BEGIN SysInit */

  /* USER CODE END SysInit */

  /* Initialize all configured peripherals */
  MX_GPIO_Init();

Just make sure that the .noinit is placed in the script AFTER .bss, not between .data and .bss. :)
