摘　　要：详细说明了嵌入式系统中常用的NOR Flash存储器建立VxWorks TrueFFS文件系统的方法。首先配置完整的DOS文件系统支持,包含核心TrueFFS组件和翻译层组件;然后编写MTD层和Socket层驱动程序;最后在TrueFFS的NOR Flash驱动上挂接VxWorks DOS文件系统,并进行了简单的测试。This paper describes the method to establish the TrueFFS file system of embedded real-time operating system VxWorks, taking SST39VF1601 NOR Flash as an example. Firstly, DOS file system is configured, including the TrueFFS core component and the translation layer according to the technology used by SST39VF1601. Secondly, MTD layer and Socket layer Drivers are written. Lastly, the VxWorks DOS file system is mounted on a TrueFFS Flash drive, and simple test is carried out.
