笔者使用的是华恒公司提供的基于at91rm9200的开发板，公司提供的开发环境使用Linux内核是2.4, 交叉编译环境也比较老，由于笔者用到的驱动对2.4内核支持不好（尤其在arm上）。笔者决定自己移植2.6内核到该款开发板上，目前工作已经基本完成。 本文第一部分介绍了交叉编译环境的建立，基本内核的移植过程。其中对部分Linux源代码的修改方法虽然是适用于华恒的板，不过对其他平台也有借鉴价值。-author used the huaheng company based at91rm9200 development boards, provide development environment is the use of Linux kernel 2.4, cross-compiler environment is also a veteran, As I drive right to use the 2.4 kernel support well (especially in the arm.). I decided to transplant themselves to the 2.6 kernel development board which, at present the work has been basically completed. This paper first describes the cross-compiler environment of the establishment, the basic core of the transplanting process. Which part of the Linux source code modification method Although huaheng is applicable to the plate, But for other platforms are also reference value.
