fsc100开发板
交叉编译工具：arm-cortex_a8-linux-gnueabi-gcc
- 平台代码修改
vim arch/arm/mach-s5pc100/mach-smdkc100.c
- 添加需要的头文件
#if defined (CONFIG_DM9000)
#include <linux/dm9000.h>
#include <linux/irq.h>
#endif
- 平台设备的添加
/* DM9000 Support */
#if defined(CONFIG_DM9000)

};
#endif
- 平台设备列表的添加：
在smdkc100_devices[]结构体数组中添加如下内容：
#if defined(CONFIG_DM9000)
&s5pc100_device_dm9000,
#endif
- 配置内核
$ make menuconfig
- 网络配置：
[*] Networking support (NEW) —>
Networking options —>
<*> Packet socket
<*> Unix domain sockets
[*] TCP/IP networking
[*] IP: multicasting
[*] IP: kernel level autoconfiguration
[*] IP: BOOTP support
- 网卡驱动配置
Device Drivers —>
[*] Network device support —>
[*] Ethernet (10 or 100Mbit) —>
<*> DM9000 support
- 网络文件系统的配置
File systems —>
[*] Network File Systems —>
<*> NFS client suppor
[*] NFS client support for NFS version 3
[*] NFS client support for the NFSv3 ACL protocol extension
[*] Root file system on NFS
- 编译内核，并拷贝到tftpboot目录下
$ make zImage
$ cp arch/arm/boot/zImage /tftpboot
- 启动开发板，修改内核启动参数，通过NFS方式挂载根文件系统
