摘要
提出了一种针对采用的STM32控制器的基于CAN总线的分布式系统程序在线更新方案,主控节点利用TFTP协议从以太网获得更新程序,再利用CAN通过分块文件传输协议更新各个节点的程序。并简要介绍了STM32的启动流程以及程序加载的方法。
This paper presents a design of online updating for the can bus based distributed control system.By using TFTP protocol, the system gets firmware from the internet.Then firmware is transmitted to the corresponding node through can bus by using a chunked transfer protocol.Also there is a briefly description of the boot sequence of stm32 and how to load the application.
