摘要
轨道车辆微控制器产品在开发、生产、交付、维护等环节,会遇到各种需要通过IAP对微控制器进行固件更新的应用场景,可以说IAP贯穿一款产品的整个生命周期.介绍嵌入式操作系统MicroLite的组网固件更新组件,该组件支持以太网、CAN总线通信接口对多个微控制器嵌入式设备实现组网升级,已在轨道车辆批量装车运行,效果良好.
Abstract
In the development,production,delivery,maintenance of rail vehicle microcontroller products,we will en-counter various application scenarios that need to upgrade the firmware of microcontrollers through IAP,and it can be said that IAP runs through the whole life cycle of a product.This paper introduces the networking firmware update component of embedded operating system MicroLite,which supports Ethernet and CAN bus communication interface for multiple micro-controller embedded devices to achieve networking update,and has been run in rail vehicles with good results.
