2、添加配置文件<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
a.將smdk2410.h複製爲tocore2440.h，其文件修改如下：
1)添加宏#undef CONFIG_SKIP_LOWLEVEL_INIT (line40)
2)註釋2410宏定義：
//#define CONFIG_S<?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />3C2410 1
//#define CONFIG_SBC2410X 1
3)添加2440宏定義：
#define CONFIG_S3C2440 1
#define CONFIG_TOCORE2440 1
#define CONFIG_TOCORE2440_LED 1 //添加點燈宏定義
#define CONFIG_S3C2440_NAND_BOOT 1//Nandflash啓動
4)註釋CS8900網卡宏定義（在line72添加#if 0,在line76 添加#endif），添加DM9000網卡宏定義：
#define CONFIG_DRIVER_DM9000 1
#define CONFIG_DM9000_USE_16BIT 1
#define CONFIG_DM9000_BASE 0x20000300
#define DM9000_IO 0x20000300
#define DM9000_DATA 0x20000304
#define CONFIG_DM9000_NO_SROM 1
#undef CONFIG_DM9000_DEBUG
#define CONFIG_NET_MULTI
5)在命令行宏定義中添加如下宏定義：
#define CONFIG_CMD_ASKENV
#define CONFIG_CMD_DHCP
#define CONFIG_CMD_PING
#define CONFIG_CMD_NAND
#define CONFIG_CMD_SAVEENV
#define CONFIG_BOOTDELAY 3 //設置系統啓動等待時間
#define CONFIG_BOOTARGS "console=ttySAC0 root=/dev/nfs "
"nfsroot=192.168.2.199:/fs " /
"ip=192.168.2.69:" //NFS支持
#define CONFIG_ETHADDR 08:00:3e:26:0a:5b //打開MAC
#define CONFIG_IPADDR 192.168.2.69 //定義自身IP
#define CONFIG_SERVERIP 192.168.2.105 //定義服務器IP
#define CONFIG_BOOTCOMMAND "dhcp; bootm" //打開DHCP
//line154之後添加如下宏定義
#define CONFIG_SYS_PROMPT "[tocore2440 ]# " //修改啓動標識
#define CONFIG_SYS_LOAD_ADDR 0x31000000 //下載地址
#define CONFIG_ENV_ADDR 0x060000 //斷電保存地址
#define CONFIG_ENV_IS_IN_NAND 1 //Nandflash
#define CONFIG_ENV_OFFSET 0X60000 //整個寄存器偏移地址
#define CONFIG_ENV_SIZE 0x20000 //ENV分區大小
#define MTDPARTS_DEFAULT "mtdparts=nandflash0:384k(bootloader),"/
"128k(params)," /
"5m(kernel)," /
"-(root)" //Nandflash默認設置
#define NAND_MAX_CHIPS 1 //Nandflash最大個數
#define CONFIG_MTD_NAND_VERIFY_WRITE //校驗
#if defined(CONFIG_TOCORE2440_LED) //點燈宏定義
/* 添加對GPIO寄存器設置的宏定義 */
#define GPIO_CTL_BASE 0x56000000
#define oGPIO_B 0x10
#define oGPIO_CON 0x0
#define oGPIO_DAT 0x4
#define oGPIO_UP 0x8
#endif
#define STACK_BASE 0x33f00000
#define STACK_SIZE 0x10000
