摘要
为克服车载嵌入式设备难以集中回收进行软件升级的缺点,提出了一种基于WiFi通信的远程软件升级方法。该方法对微控制器FLASH存储空间进行有效分配,设计IAP功能,利用WiFi通信接口采用TFTP协议下载新软件到FLASH,实现嵌入式软件在线升级。给出了升级方法的详细设计和程序流程,升级速度快,受环境影响小。该方法可应用于移动分布式嵌入式设备中。
To overcome the difficulty of gathering all automotive embedded devices to upgrade software, this paper proposes a remote software upgrade method based on WiFi Communication. The method allocates the microcontroller FLASH memory space effectively, and designs IAP function by using WiFi communication interface to download new software to FLASH memory. This article gives a detailed design and program flow method. This method can be applied to distributed embedded mobile devices.
