And the increasingly wide range of applications,the complexity of embedded systems is constantly increasing. Now,the embedded operating system has become one of the most important part of the embedded system. 下载后可任意编辑In the embedded operating systems,The Linux operating system has become more and more attened ， because of its open source,small core,good performance;what’s more,Linux2.6 introduces many new features that make it an excellent and suitable operating system for embedded computing. Undoubtedly, the embedded Linux operating systemwill bring large economic value and application prospects. This thesis is accomplished based on the automatic meter reading system for a power company in Nanjing, and the main contribution is to introduce transplantation of the embedded Linux system, as well as the driver development of corresponding peripheral device. This paper accomplish the transplantation of the embedded Linux system based on AT91SAM9260EK,and including build the development platform,build the embedded cross-compile environment; Based on the analysis of the booting and loading process—BootLoader of the embedded system,implements the transplantation of Uboot on the platform. After the detailed analysis of the kernel structure and booting process of Linux system, according to the terminal hardware platform,analyze the process of transplantation and cut of the Linux kernel. In accordance with the application requirements,we select the YAFFS2 as our root file syetem,and detailedly introduce the process of the implementation of the YAFFS2 f...
