Jump to Freertos application

[Qusai]

Hi all,

I have developed a bootloader for STM32F412, the bootloader works perfectly, however, when I change the user app to be FreeRTOS based, it ceases to work.

I added a blink led in the Hard Fault in both the bootloader and app, but both were not triggered.

Any idea what is going on?

void jump_to_application(void) {
    void (*app_reset_handler)(void);
    uint32_t msp_value = *(volatile uint32_t*)(APP_START_ADDRESS + APP_HEADER_SIZE);
    uint32_t reset_handler_address = *(volatile uint32_t*)(APP_START_ADDRESS + APP_HEADER_SIZE + 4);

    __disable_irq();

    HAL_RCC_DeInit();
    HAL_DeInit();

    SysTick->CTRL = 0;
    SysTick->LOAD = 0;
    SysTick->VAL = 0;


    for (uint32_t i = 0; i < 8; i++)
    {
        NVIC->ICER[i] = 0xFFFFFFFF;
        NVIC->ICPR[i] = 0xFFFFFFFF;
    }

    __enable_irq();

    __set_MSP(msp_value);
    __set_PSP(msp_value);
    __set_CONTROL(0);
    app_reset_handler = (void*)reset_handler_address;
    app_reset_handler();
} 

Thanks in advance.

Nothing wrong with the code posted. If app doesn't work, I wouldn't suspect an issue with the bootloader.

General rules:

• Don't jump to application from within an interrupt.
