摘　　要：本文阐述Boot在嵌入式程序刷写中的架构设计研究与应用。嵌入式程序主要包含两部分:一部分是用来更新应用程序的引导加载程序,即Boot程序;另一部分是应用程序,即APP程序。随着客户需求的多样性和智能化,应用程序也不断地迭代升级,Boot程序也需要升级,所以还需要一段程序来升级Boot程序。升级Boot程序时存在风险性,所以要保证升级Boot程序和App程序时正确稳定,安全可靠。This paper describes the architecture design and application of Boot in embedded program writing.Embedded program mainly consists of two parts,one is used to update the application software,that is,the Bootloader.The other part is the application software,the APP program.With the diversity and intelligence of customer demand,the application is also constantly iterative upgrade,Bootloaderalso needs to upgrade,so also need a program to upgrade the Bootloader.The upgrade is risky,it is necessary to ensure that the upgrade of the Boot program and App program to be correct and stable,safe and reliable.
