一、移植環境:
1、 Ubuntu 10.10發行版
2、 u-boot.bin
3、 目標機:FS_S5PC100平台
4、 交叉編譯器 arm-cortex_a8-linux-gnueabi-gcc
u-boot.bin下載:

二、移植步驟
1、平台代碼修改
$ vim arch/arm/mach-s5pc100/mach-smdkc100.c
#if defined(CONFIG_DM9000) #include <linux/dm9000.h> #include <linux/irq.h> #endif
/** DM9000 Support **/ #if defined(CONFIG_DM9000) static struct resource dm9000_resources[] = { [0] = { .start = 0x88000000, .end = 0x88000000 + 0x3, .flags = IORESOURCE_MEM, }, [1] = { .start = 0x88000000 + 0x4, .end = 0x88000000 + 0x4 + 0x3, .flags = IORESOURCE_MEM, }, [2] = { .start = IRQ_EINT(10), .end = IRQ_EINT(10), .flags = IORESOURCE_IRQ | IRQ_TYPE_LEVEL_HIGH, }, }; static struct dm9000_plat_data s5pc100_dm9000_platdata = { .flags = DM9000_PLATF_16BITONLY, .dev_addr[0] = 0x00, .dev_addr[1] = 0x00, .dev_addr[2] = 0x3e, .dev_addr[3] = 0x26, .dev_addr[4] = 0x0a, .dev_addr[5] = 0x00, }; static struct platform_device s5pc100_device_dm9000 = { .name = "dm9000", .id = -1, .num_resources = ARRAY_SIZE(dm9000_resources), .resource = dm9000_resources, .dev = { .platform_data = & s5pc100_dm9000_platdata, }, }; #endif
#if defined(CONFIG_DM9000) &s5pc100_device_dm9000, #endif
2、配置內核
$ make menuconfig
[*] Networking support(NEW) ---> Networking option ---> <*> Packet socket <*> Unix domain socket [*] TCP/IP networking [*] IP: multicasting [*] IP: kernel level autoconfiguration [*] IP: BOOTP support
[*] Device Drivers ---> [*] Network device support ---> [*] Ethernet(10 or 100Mbit) ---> <*> DM9000 support
File systems ---> [*] Network File Systems ---> <*> NFS client support [*] NFS client support for NFS version 3 [*] NFS client support for the NFSv3 ACL protocol extension [*] Root file system on NFS
三、編譯內核,並拷貝到tftpboot目錄下
$ make zImage $ cp arch/arm/boot/zImage /tftpboot
啟動開發板,修改內核啟動參數,通過NFS方式掛載根文件系統
