HTTP模式下STM32程序远程升级设计

Remote Upgrade Design of STM32 Program in HTTP Mode

针对嵌入式终端设备架设分散、数量庞大以及应用程序更新迭代速度快带来的程序升级困难局面,运用STM32微控制器的在应用中编程(IAP)原理,设计了通过以太网远程升级程序的方案。HTTP协议和LwIP协议的使用,不仅让整个方案具备高安全性、可靠性、易用性,还有效降低了硬件资源的消耗。该方案稳定、可靠,操作简单,可以广泛应用于网络环境下的IAP升级,具有较高的推广价值。

In response to the difficulty of upgrading programs due to the scattered and large number of embedded terminal devices and the rapid iteration of application updates,a solution is designed to upgrade programs remotely via Ethernet using the STM32 microcontroller in application programming(IAP)principle.The use of HTTP and LwIP protocols not only provides high security,reliability and ease of use,but also effectively reduces the consumption of hardware resources.The solution is stable,reliable and simple to operate,and can be widely used for IAP upgrades in a network environment,which has high promotion value.
