：ARM Linux 在AT91RM9200 平台上的移植，步骤包括下载安装内核源码、建立交叉编译环境及以压缩或非压缩方式配置和编译内核。其文件系统的建立及程序开发均在宿主机上完成，再通过串口、网口或者JTAG口烧写至目标板。-: AT91RM9200 ARM Linux platform in the transplant, steps include download and install the kernel source code, the establishment of cross

本代码是基于linux嵌入式的交叉编译器，已经配置好了，适合大多数用户尤其是初学者对交叉编译环境还很陌生的同学-This code is based on embedded linux cross compiler has been configured, for most users, especially beginners cross-compiler environment are still unfamiliar with the students

一个可以在Arm Linux环境下运行的对时程序，基于socket编写，可移植性强。 配置好了交叉编译工具链之后，直接make即可。 代码采用C++的面向对象开发，简单易用，模块清晰，便于裁剪和模块复用。(A time program that can run in Arm Linux environment is written based on socket, and has strong portability. After configuring the cross compila
