零代码玩转OTA升级
本帖最后由 akqbdlk 于 2020-6-22 09:50 编辑前言： 前边讲过stm32通用bootloader的实现方法，没有看过的，可以参考这一篇**：STM32通用Bootloader——FOTA：https://blog.csdn.net/sinat_31039061/article/details/106344081，这一篇将在上篇bootloader的基础上，介绍app如何通过多种固件下载器实现OTA升级。先看下演示视频，此视频演示了四种升级方式，分别是：
[*]阿里云物联网平台OTA
[*]HTTP OTA
[*]Ymodem OTA
[*]不用app，使用Bootloader中的Ymodem OTA
演示视频：https://www.bilibili.com/video/bv1zK411p7uH
此项目硬件使用的是STM32F429开发板，代码全部使用RT-Thread Studio搭积木的方式实现，仅仅改动了几行代码，开发效率非常高。此项目的地址：https://gitee.com/Aladdin-Wang/RT-FOTA-STM32L431.git使用到的软件包和组件：
1.准备工作1.1 新建工程
由于此项目使用的esp8266需要一个串口，我使用的是uart2，所以需要还需要配置uart2
增加uart接收缓冲区大小：
1.2 打开fal和at device软件包
打开fal软件包
配置sfud组件
配置SPI

编译工程，将bin文件上传到阿里云：阿里云不支持rbl格式的文件，直接将rt_ota_packaging_tool生成的rbl文件后缀改为bin，上传即可。最后使用ali_ota_sample命令升级：https://img-blog.csdnimg.cn/20200620140025680.png
3.HTTP OTA和Ymodem OTA配置ota_downloader软件包如果暂时没有自己的服务器，可以使用MyWebServer进行测试：配置完MyWebServer，可以打开浏览器输入IP地址查看：使用http_ota命令进行http_ota升级：https://img-blog.csdnimg.cn/20200620135917276.png使用ymodem_ota命令进行ymodem_ota升级：https://img-blog.csdnimg.cn/20200620135956526.png4.不适用APP进行升级rt-fota集成了ymodem_ota，上电短按恢复出厂设置按钮即可进入rt-fota命令行模式，通过ymodem_ota命令即可进行升级：联系作者：欢迎关注本人公众号，加**流：
