前言: 当了解了stm32通用bootloader的实现方法,今天给大家在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:

  1. 阿里云物联网平台OTA
  2. HTTP OTA
  3. Ymodem OTA
  4. 不用app,使用Bootloader中的Ymodem OTA

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:

writefile error_temporary file write failure

在这里插入图片描述

1.准备工作

1.1 新建工程

writefile error_temporary file write failure

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:

writefile error_temporary file write failure

增加uart接收缓冲区大小:

1.2 打开fal和at device软件包

配置fal软件包

writefile error_temporary file write failure

配置sfud组件

writefile error_temporary file write failure

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。

writefile error_temporary file write failure

最后使用ali_ota_sample命令升级:

writefile error_temporary file write failure

3.HTTP OTA和Ymodem OTA

配置ota_downloader软件包

writefile error_temporary file write failure

如果暂时没有自己的服务器,可以使用MyWebServer进行测试:

writefile error_temporary file write failure

配置完MyWebServer,可以打开浏览器输入IP地址查看:

writefile error_temporary file write failure

使用http_ota命令进行http_ota升级:

writefile error_temporary file write failure

使用ymodem_ota命令进行ymodem_ota升级:

writefile error_temporary file write failure

4.不使用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:

writefile error_temporary file write failure
