5 RTT app跳转后运行一段时间就会hardfault

发布于 2024-04-15 19:55:44 浏览：478 订阅该版

用的是华大的hc32L196  bootloader是裸机跑的 大概分配的是30K的大小 然后app跑的是rtt bootloader没有任何硬件初始化 也没涉及到任何中断 按照官方iap例程在startup里 把new_vect_table 0x7800加上了 能正常跳转 能初始化thread  但是过会马上会进hardfault 如果从bootloader 加载 直接运行app的话没有问题

```c
{
 __disable_irq();

/* 关闭所有中断，清除所有中断挂起标志 */
  for (uint32_t i = 0; i < 1; i++)
  {
    NVIC->ICER[i]=0xFFFFFFFF;
    NVIC->ICPR[i]=0xFFFFFFFF;
  }

Boot2APP();             //跳转到APP部分
 }
```

```c
void Boot2APP(void)
{
	/* Test if user code is programmed starting from address "APPLICATION_ADDRESS" */
	//因为用户程序开始位置(0x08004000处)的前4个字节存放的是堆栈的地址，堆栈地址必定是指向RAM空间的，而STM32的RAM空间起始地址为0x20000000，所以要进行判断。
	if ((FLASH_If_Read_Word(APPLICATION_ADDRESS) & 0x2ff00000 ) == 0x20000000)
	{
		/* Jump to user application */
		//程序跳转地址的确认，前面已经说过0x08004004处的4个字节存放的是复位函数的入口地址，
		//该句的意思为获得(ApplicationAddress + 4)地址处的数据，即为获得新的复位函数入口地址。
		JumpAddress = *(__IO uint32_t*) (APPLICATION_ADDRESS + 4);
		
		//令Jump_To_Application这个函数指针指向复位函数入口地址。
		JumpToApplication = (pFunction) JumpAddress;
		
		/* Initialize user application's Stack Pointer */
		//堆栈的初始化，重新设定栈顶代地址，把栈顶地址设置为用户代码指向的栈顶地址。
		__set_MSP(*(__IO uint32_t*) APPLICATION_ADDRESS);
		__set_CONTROL(0);
		
		//跳转到新的复位函数。
		JumpToApplication();
	}
}
```

```c
void rt_hw_board_init(void)
{

App_SystemClkInit_RCH(SysctrlRchFreq16MHz);  //
    Sysctrl_SetHCLKDiv(SysctrlHclkDiv1);
    Sysctrl_SetPCLKDiv(SysctrlPclkDiv1);
		Sysctrl_SetRTCAdjustClkFreq(SysctrlRTC16MHz);  //补偿高速时钟源   
    Sysctrl_ClkSourceEnable(SysctrlClkRCL,TRUE);     //配置内部低速时钟作为RTC时钟
    Sysctrl_SetRCLTrim(SysctrlRclFreq32768);
		SysTick_Config(SystemCoreClock / RT_TICK_PER_SECOND);
		 __enable_irq();
   
    /* 
     * TODO 1: OS Tick Configuration
     * Enable the hardware timer and call the rt_os_tick_callback function
     * periodically with the frequency RT_TICK_PER_SECOND. 
     */

/* Call components board initial (use INIT_BOARD_EXPORT()) */
#ifdef RT_USING_COMPONENTS_INIT
    rt_components_board_init();
#endif

#if defined(RT_USING_USER_MAIN) && defined(RT_USING_HEAP)
    rt_system_heap_init(rt_heap_begin_get(), rt_heap_end_get());
#endif
}

#ifdef RT_USING_CONSOLE

{
	
    return 0;
}
