# 1 IAP ## 1.1 IAP简介 IAP（In Application Programming）即在应用编程。是用户自己的程序在运行过程中对User Flash的部分区域进行烧写。实现代码升级，可通过UART、SPI、IIC、USB等等传递需要升级的固件。实现即将flash或者其他存储器分成多个段，存储升级的代码，一般设计分为两个部分，第一部分用于实现通讯升级代码，叫bootloader，第二部分为应用程序，即正常运行的代码。 ## 1.2 启动流程 程序启动后，先从 0x08000004 处取出复位中断向量地址，执行完复位中断函数后跳转到IAP 程序 main 函数中执行[①]。 当发生中断请求后，程序跳转到中断向量表中取出中断函数入口地址，再跳转到中断服务函数中执行[②]，执行完中断函数后返回 main 函数中[③]，然后执行 IAP 过程，成功后跳转到 APP程序[④]。 从偏移后的中断向量表得到相应中断函数地址，执行相应新的中断服务函数后，回到 APP的 main 函数中[⑤]。后面[⑥⑦⑧]的过程和前述一致。 <ignore_js_op> <img style="cursor:pointer;" id="aimg_795224" aid="795224" src="static/image/common/none.gif" onclick="zoom(this, this.getAttribute('zoomfile'), 0, 0, '0')" zoomfile="data/attachment/forum/202403/16/213350idqn1qdr7r73dyiy.png" file="data/attachment/forum/202403/16/213350idqn1qdr7r73dyiy.png.thumb.jpg" inpost="1" onmouseover="showMenu({'ctrlid':this.id,'pos':'12'})" /> <div class="tip tip_4 aimg_tip" id="aimg_795224_menu" style="position: absolute;

老兄，文章中 2.1 Bootloader 设计，第一处应用程序的地址是 0x08010000,你打错了写成 0x0801000 少了一个零
