Bootloader (STM32L496RG) application stuck at first HAL_Delay

I create 2 simple applications on Nucleo-L476RG.

Both application have default settings from STM32CUBEIDE.

1 - bootloader - just jump to 0x08010000

2 - Application - led flashings with HAL_Delay function

Bootloader jumps into application, pplication starts - then stuck into HAL_Delay.

See the modification to both app:

'Bootloader':

/* USER CODE BEGIN 0 */

typedef void (*pFunction)(void); /*!< Function pointer definition */

#define APP_ADDRESS (uint32_t)0x08010000

void jump2APP(){

uint32_t JumpAddress = *(__IO uint32_t*)(APP_ADDRESS + 4);

pFunction Jump  = (pFunction)JumpAddress;

HAL_RCC_DeInit();

HAL_DeInit();

__disable_irq();

SysTick->CTRL = 0;

SysTick->LOAD = 0;

 SysTick->VAL = 0;

SCB->VTOR = APP_ADDRESS;

__set_MSP(*(__IO uint32_t*)APP_ADDRESS);

Jump();

}

/* USER CODE END 0 */

[....]

 uint8_t i=20;

 HAL_GPIO_TogglePin(LD2_GPIO_Port,LD2_Pin);

 while (1)

 {

 /* USER CODE END WHILE */

 /* USER CODE BEGIN 3 */

  HAL_GPIO_TogglePin(LD2_GPIO_Port,LD2_Pin);

HAL_Delay(i*30+1);

if(!i--)

jump2APP();

 }

Application:

* USER CODE BEGIN WHILE */

volatile uint32_t cnt=0;

while(cnt++<500000);

cnt=0;

HAL_GPIO_TogglePin(LD2_GPIO_Port,LD2_Pin);

while(cnt++<5000000);

cnt=0;

HAL_GPIO_TogglePin(LD2_GPIO_Port,LD2_Pin);

while(cnt++<5000000);

cnt=0;

HAL_GPIO_TogglePin(LD2_GPIO_Port,LD2_Pin);

while(cnt++<5000000);

cnt=0;

HAL_GPIO_TogglePin(LD2_GPIO_Port,LD2_Pin);

while(cnt++<5000000);

 while (1)

 {

 /* USER CODE END WHILE */

 /* USER CODE BEGIN 3 */

  HAL_GPIO_TogglePin(LD2_GPIO_Port,LD2_Pin);

  HAL_Delay(100);

 }

 /* USER CODE END 3 */

And in the linker file:

MEMORY

{

 RAM  (xrw)  : ORIGIN = 0x20000000,  LENGTH = 96K

 RAM2  (xrw)  : ORIGIN = 0x10000000,  LENGTH = 32K

 FLASH  (rx)  : ORIGIN = 0x8010000,  LENGTH = 1024K

}
