Bootloader unable to jump to application

[khaleel453]

Hi

With your code as reference i successfully built and loaded bootloader and user application binaries for "STM32F411RE" evolution kit.
issue :
Bootloader unable to jump to user application. Below is my goto application function
`static void goto_application(void)
{
printf("Loading Application....\r\n");

void (app_reset_handler)(void) = (void)(((volatile uint32_t) (0x08008000 + 4U)));

__set_MSP((volatile uint32_t) 0x08008000);

// Turn OFF the Green Led to tell the user that Bootloader is not running
HAL_GPIO_WritePin(GPIOA, GPIO_PIN_5, GPIO_PIN_RESET ); //Green LED OFF
app_reset_handler(); //call the app reset handler
}`
bootloader storage : 0x08000000 to 0x08007800 [30kB]
Application Flash range : 0x08008000 to 0x08018000 [64KB]

Bootloader is going to error handler while running app_reset_handler() function.

Could you please help me out in solving this issue.
Thanks in advance.

Best Regards

I can able to see a few differences in your code. Can you please try using the below function in our project and let us know?

static void goto_application(void)
{
  printf("Loading Application....\r\n");

  void (*app_reset_handler)(void) = (void*)(*((volatile uint32_t*) (0x08008000 + 4U)));

  //__set_MSP((volatile uint32_t) 0x08008000);

  // Turn OFF the Green Led to tell the user that Bootloader is not running
  HAL_GPIO_WritePin(GPIOA, GPIO_PIN_5, GPIO_PIN_RESET ); //Green LED OFF
  app_reset_handler(); //call the app reset handler
}

Thanks for your response.
I tried it but unfortunately getting the same error.
