How to jump to App as a Bootloader?
Just like this:
- write your App starting address: #define APP_START (0x08005000)
void jump_to_app()
{
//-- jump to application image: new SP and reset vector address
volatile uint32_t *uwImagePtrW;
volatile uint32_t newMSP, jmpAddr;
uwImagePtrW = (uint32_t *)APP_START;
newMSP = *uwImagePtrW;
uwImagePtrW++;
jmpAddr = *uwImagePtrW;
//-- reset peripherals to guarantee flawless start of user application
HAL_GPIO_DeInit(GPIOA, GPIO_PIN_0);
HAL_TIM_Base_Stop_IT(&htim2);
HAL_TIM_Base_DeInit(&htim2);
SysTick->CTRL &= ~SysTick_CTRL_ENABLE_Msk;
HAL_RCC_DeInit();
HAL_DeInit();
/* let's do The Jump! */
__set_MSP(newMSP);
asm("bx %0 n" : : "r" (jmpAddr));
}
Done!!!
