这家伙很懒，什么也没写！

具体什么错误，boot 跳转 到 app 是否正常? 以下供参考

BOOT:
```c
//boot跳转app
void boot_jump_to_app(u32 application_addr)
{
    typedef void (*app_func_t)(void);
    u32 app_addr = application_addr;
    u32 stk_addr = *((volatile u32*) app_addr);
    app_func_t app_func = (app_func_t) (*((volatile u32*) (app_addr + 4)));
    if ((((u32) app_func & 0xff000000) != 0x08000000) || ((stk_addr & 0x2ff00000) != 0x20000000))
    {
        printf_error("no legitimate application!\r\n");
        return;
    }
    printf_info("jump to application running!\r\n");
    delay_ms(200);

/* 恢复运行环境到初始状态 */
    __disable_irq();
    SysTick->CTRL = 0;
    SysTick->LOAD = 0;
    SysTick->VAL = 0;
    __set_CONTROL(0);
    /************************/

__set_MSP(stk_addr);  //set msp and jump
    app_func();  //Jump to application running
    printf_error("bootloader jump to application failed!\r\n"); //if success,never go here!
}
```

APP:
