嵌入式操作系统VxWorks中TFFS文件系统的构建

包含Tornado之TrueFFS编程者指南.pdf 参考内容二_VxWorks_IO和文件系统.pdf TrueFFS学习.doc等vxworks tffs的相关资料

摘要：目前的嵌入式系统多使用FLASH作为主存，因此，如何有效管理FLASH上的数据非常重要。文章以MX29LV160BT芯片为例，讨论了在VxWorks操作系统下Nor Flash上建立TFFS文件系统的一般步骤，从而为FLASH上的数据管理提供了理想的选择方式，同时也为开发者和用户升级程序提供了方便。关键词：VxWorks Flash MTD TFFS 文件系统 嵌入式系统正随着Internet的发展而在各个领域得到广泛的应用，作为一个优秀的操作系统，VxWorks实现了比其他实时操作系统更好的有效性、商用性、可裁减性以及互操作性，广泛应用在通信、军事、航空、航天等高精尖技术及实时性要求
