摘　　要：Linux作为一种优秀的免费操作系统,近几年在嵌入式领域异军突起,成为了最有潜力的嵌入式操作系统。然而处理器的多样性决定了不可能有构造一个通用的操作系统,必须根据处理器的不同进行相关的移植。基于目前在i.MX21处理器上还没有对Linux2.6内核进行成功的移植,详细介绍了嵌入式Linux2.6内核在i.MX21处理器上的移植过程。对硬件终端平台,U-BOOT的移植,交叉工具链的制作,BSP(板级支持包)的开发,根文件系统制作,内核调试等核心技术都进行了详细的论述。最终实现了Linux2.6内核的成功移植。As an excellent free OS （operation system）, Linux becomes the most potential OS of embedded system recently. The diversity of processor decides that it is impossible to architect a general OS, and OS should be transplanted by different type of processor. The transplant of Linux2.6 core haven＇ t been succeed based on i. MX21, and describes the transplant process of embedded Linux2.6 core in the i. MX21 proessaor. It is discussed in detail that the hardware platform, U-BOOT transplant, cross-tool chain,BSP, root file system production process and debug core technology. In the end, the research successfully achieved the transplant of Linux2.6 kenel.
