摘要
采用RISC(精简指令集计算机)架构的32位ARM(高级RISC)微控制器,具有低功耗(内核工作电压一般为1.8 V)、高性能、运算速度快(一般以MIPS为单位)、执行效率高等优点。介绍了韩国三星公司的基于ARM920T内核的S3C2410芯片嵌入式Linux系统移植过程,构建出最基本的ARM9的Linux开发环境。所做的工作有移植U-Boot,移植并裁剪Linux内核以及用busybox制作的根文件系统。
Using RISC （ Reduced Instruction Set Computer） construction, an ARM （Advanced RISC Machines） of 32 bits Microcontroller has low power comsumption consume （VDDCORE power supply voltage is 1.8 V）, high capability, and high executing speed （the unit is MIPS）. This paper introduces the embedded Linux system transplantation process on ARM920T-core-based S3C2A10 chip of Samsung company and a basic ARM9＇s Linux development environment is established. What we have done are transplantation of U-Boot, transplantation and cutting Linux kernel, as well as creation of own cramfs root file system using busybox.
