如果不是用qboot做的bootloader，那么跳转代码最好参考qboot中hc32的跳转代码做些修改

代码我是抄的华大官方的iap 例子,已对修改成和你的一样了，仍然不能运行，下面是bootloader跳转代码

```c
/**
 * @brief  Jump from boot to app function.
 * @param  [in] u32Addr                 APP address
 * @retval LL_ERR                       APP address error
 */
int32_t IAP_JumpToApp(uint32_t u32Addr)
{
    uint32_t u32StackTop = *((__IO uint32_t *)u32Addr);
    uint32_t WriteOk = *((__IO uint32_t *)(u32Addr - 4));     //获取APP程序是否写入完成标志
    if(WriteOk == 0x01){        //如果写成0x01,表示SD卡程序已经顺利写进flash,可以执行跳转检查
        /* Check stack top pointer. */
        if ((u32StackTop > SRAM_BASE) && (u32StackTop <= (SRAM_BASE + SRAM_SIZE))) {
						__disable_irq();
            IAP_PeriphDeinit();
						qbt_reset_periph();
						for(int i=0; i<144; i++)
						{
								NVIC_DisableIRQ((IRQn_Type)i);
								NVIC_ClearPendingIRQ((IRQn_Type)i);
								//enIrqResign(i);
						}
						SysTick->CTRL = 0;
						SysTick->LOAD = 0;
						SysTick->VAL = 0;
						CLK_MrcCmd(ENABLE);
						CLK_SetSysClockSrc(CLK_SYSCLK_SRC_MRC);
						EFM_FWMC_Cmd(ENABLE);
						EFM_SetWaitCycle(EFM_WAIT_CYCLE0);
						EFM_FWMC_Cmd(DISABLE);
						//__enable_irq();
            /* Jump to user application */
            uint32_t JumpAddr = *(__IO uint32_t *)(u32Addr + 4U);
            JumpToApp = (func_ptr_t)JumpAddr;
            /* Initialize user application's Stack Pointer */
						//__set_PSP(u32StackTop);
						//__set_CONTROL(0);
            //__set_MSP(u32StackTop);
						__set_CONTROL(0);
						__set_MSP(u32StackTop);
						
						
						
            JumpToApp();
        }
    }
    return LL_ERR;
}
```
下面是app跳转的偏移，地址为0xA004,多偏移了4字节，是我用来存放app写入完成标志的，防止APP写的时候SD卡被拔出来,APP未写入完成，bootloader就跳转了程序

```c
/**
 * This function will initial your board.
 */
void rt_hw_board_init()
{
		SCB->VTOR = 0xA004UL;
    SysCLK_Init();
		GPIOInit();
    /* System Clock Update */
    SystemCoreClockUpdate();
    /* System Tick Configuration */
    _SysTick_Config(SystemCoreClock / 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
}
```

我使用MDK分散加载文件如下配置，偏移地址是0x00020000

```c
; ****************************************************************
; Scatter-Loading Description File
; ****************************************************************
LR_IROM1 0x00020000 0x00058000  {    ; load region size_region
    ER_IROM1 0x00020000 0x00058000  {  ; load address = execution address
        *.o (RESET, +First)
        *(InRoot$$Sections)
        .ANY (+RO)
        .ANY (+XO)
    }
    RW_IRAM1 0x1FFF8000 0x0002F000  {  ; RW data
        .ANY (+RW +ZI)
    }
}

```
app偏移自己写就是了，参考这个，地址根据自己偏移地址就好了。

```c
/**
 * Function    ota_app_vtor_reconfig
 * Description Set Vector Table base location to the start addr of app(RT_APP_PART_ADDR).
*/
static int ota_app_vtor_reconfig(void)
{
    //#define NVIC_VTOR_MASK   0x3FFFFF80
    /* Set the Vector Table base location by user application firmware definition */
    SCB->VTOR = RT_APP_PART_ADDR ;

return 0;
}
INIT_BOARD_EXPORT(ota_app_vtor_reconfig);
```
boot程序配置，可以参考楼上写的QBOOT代码，其中跟平台相关配置我是这样处理的

```c
/*
 * qboot_stm32.c
 *
 * Change Logs:
 * Date           Author            Notes

跳转时注意时钟切换问题，我是发现在boot跳转前把时钟切换到内部8M，在app切换成外部时钟时，尽管已经检测时钟稳定标志，但实际切换运行不起来。所以我BOOT直接不切换了，直接把BOOT跟APP时针配置得一样。
