Abstract: 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.
