Switching from STM32F407VGT6 to STM32F437VIT6 bootloader application problem

Hi,

I've switched to STM32F437VIT6 from STM32F407VGT6, but I also switch my bootloader application.

In this application, there is a section that jumps to the real application that we've loaded using the bootloader:

 /* Test if Key push-button is not pressed */
 if (GPIO_ReadInputDataBit(GPIOA, GPIO_Pin_0) == 0x00)
 { /* Key push-button not pressed: jump to user application */
 pFlashStartAddr = *(__IO uint32_t*)FLASH_USER_START_ADDR;
	pFlashRes = (*(__IO uint32_t*)FLASH_USER_START_ADDR) & 0x2FFE0000;
 /* Check if valid stack address (RAM address) then jump to user application */
 if (((*(__IO uint32_t*)FLASH_USER_START_ADDR) & 0x30000000 ) == 0x20000000)
 {
 /* Jump to user application */
 JumpAddress = *(__IO uint32_t*) (FLASH_USER_START_ADDR + 4);
 Jump_To_Application = (pFunction) JumpAddress;
 /* Initialize user application's Stack Pointer */
 __set_MSP(*(__IO uint32_t*) FLASH_USER_START_ADDR);
 Jump_To_Application();
 }
 }
 /* enter in IAP mode */
	else
	{
 //Initialize kernel
 osInitKernel();
 //Configure debug UART
 debugInit(115200);
...

#define ADDR_FLASH_SECTOR_23 ((uint32_t)0x081E0000) /* Base address of Sector 23, 128 Kbytes */

The loading part of my application works fine but the jumping part is not working, gives a hard fault.

Here is my scatter file:

LR_IROM1 0x08000000 0x200000
{
 ER_IROM1 0x08000000 0x200000
 {
 *.o (RESET, +First)
 *(InRoot$$Sections)
 .ANY (+RO)
 }
 
 RW_IRAM1 0x20000000 0x30000
 { 
 .ANY (+RW +ZI)
 }
 
 ARM_LIB_STACK 0x20020000 EMPTY -0x1000
 {
 }
 
 ARM_LIB_HEAP 0x20010000 EMPTY 0x0F000
 {
 }
}

How can I fix this issue?

Thanks in advance.
