摘　　要：嵌入式系统固件文件格式是远程固件更新和升级的基础,固件映像文件格式不尽相同,这些格式对远程固件进行更新和升级的灵活性和简便性有重要影响。为了使固件更新程序能够正确完成Flash写入操作,固件文件就需要克服现有格式中未包含关于映像文件详细信息的缺点。通过分析几种可更新固件文件的代码、数据和其他辅助信息,得出现有的几种固件文件的信息格式,并在现有格式基础上添加映像文件的详细信息。文中研究出的固件文件格式更加具有灵活性和高效性。The format of the embedded system＇s firmware files is the basis of remote firmware updating and upgrading, the image formats of firmware may be different, thee formats have an important impact on the flexibility and simplicity of remote firmware updating and upgrading. In order to make firmware updating procedure to finish Flash- writing operation correctly, firmware files need to overcome the shortcoming of the existing format of the image files that did not contain detail information. Based on the analysis to the code, data and other supporting information of several updated firmware files, the format of information of several existing firmware files can be found in this article, and the detail information of image files will be added to the existing formats. The format of firmware files researched on this paper will be flexibility and efficiency.
