STM32F407 HardFault_Handler 中断输出初步定位越界问题

1、测试环境：MDK + STM32F407

2、汇编重写 HardFault_Handler  中断

/* 硬件错误中断的回调 */
void HardFault_CallBack_MSP(void)
{
    unsigned int MSP = __get_MSP();
    unsigned int nextPoint1 = *((unsigned int*)MSP + 5);
    unsigned int nextPoint2 = *((unsigned int*)MSP + 6);
    unsigned int nextPoint3 = *((unsigned int*)MSP + 7);
    
    while (1)
    {
        static unsigned int i = 0;
        printf("<%s>[%d] MSP = 0x%.8X, nextPoint = 0x%.8X / 0x%.8X / 0x%.8X\r\n", 
                __func__, ++i, MSP, nextPoint1, nextPoint2, nextPoint3);
        for (int j = 0; j < 100000000; j++);
    }
}

/* 硬件错误中断的回调 */
void HardFault_CallBack_PSP(void)
{
    unsigned int PSP = __get_PSP();
    unsigned int nextPoint1 = *((unsigned int*)PSP + 5);
    unsigned int nextPoint2 = *((unsigned int*)PSP + 6);
    unsigned int nextPoint3 = *((unsigned int*)PSP + 7);
    
    while (1)
    {
        static unsigned int i = 0;
        printf("<%s>[%d] PSP = 0x%.8X, nextPoint = 0x%.8X / 0x%.8X / 0x%.8X\r\n",
                __func__, ++i, PSP, nextPoint1, nextPoint2, nextPoint3);
        for (int j = 0; j < 100000000; j++);
    }
}
