摘　　要：汽车电子发展对程序开发、软件功能、应用的便利性提出要求。在面向整车应用和生产环节,基于传统BDM、JTAG等刷写工具在现场应用中缺少便利性。Bootloader作为程序运行的启动加载引导代码,为基于总线的程序刷写,提供了解决方案。在车辆应用中,基于CAN总线的Bootloader的设计开发,是进行车辆控制模块开发中最基础也是最核心的工作之一。本文基于S32K148微控制器,采用NXP S32DS IDE开发环境实现车辆网关模块Bootloader软件开发,通过VC++实现上位机软件的开发。结果表明:Bootloader能够正确引导程序运行,准确方便地下载应用程序。The development of automotive electronics puts forward requirements for the program development,software functions,and convenience of application.In the process of vehicle application and production,the traditional tools such as BDM and JTAG are inconvenient.Bootloader,as the first code for program operation,provides a solution for downloading based on CAN-Bus.In the process of application,the design and development of Bootloader based on CAN-Bus is one of the most basic and core tasks in the development of vehicle control modules.This article is based on the S32K148 microcontroller,using the NXP S32DS IDE tool to develop the Bootloader bottom software of the vehicle GateWay module,and realizing the development of the PC software through VC++.The result shows that the Bootloader can boot the application programs correctly and download accurately and easily.
