Transplantation in the Linux system, the first transplant carried out the design and build environment, installation and configuration of the cross-compiler.Secondly, a design and implementation of the system bootloader, main contents, including transplantation of open source software U-BOOT, since the processor S3C2410 in the U-BOOT only SMDK2410 board of standards support in use must be transplanted toARM9-2440EP hardware environment, and finally, in the following steps to achieve the whole process. This is a linux system using the terminal command modified by gcc cross-compiler, and generates a target need uboot, kernel, logo, and file system image file required, and the windows XP system to download and byDNW and Super Terminal will be programmed into the target image file TQ2440 download mode, restart the development board NANDFlash mode until you see the system interface, you can begin to enter the development stage. Embedded Linux text discusses in detail the process of transplantation is given to build the embedded development environment, hardware platform based on ARM920Ts bootloader, Linux kernel and root file system migration implementations. Keywords: linux federal10 system, uboot transplantation, kernel porting. 目 录 第一章 绪 论 - 1 - 1.1嵌入式系统的概述 - 1 - 1.1.1
