一、移植环境:
1、 Ubuntu 10.10发行版
2、 u-boot.bin
3、 目标机:FS_S5PC100平台
4、 交叉编译器 arm-cortex_a8-linux-gnueabi-gcc
---------------------------------------------------------------------
二、移植步骤
1、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) 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
- 平台设备列表的添加
#if defined(CONFIG_DM9000) &s5pc100_device_dm9000, #endif
2、配置内核
$ make menuconfig
- 网络配置
[*] Networking support(NEW) ---> Networking option ---> <*> Packet socket <*> Unix domain socket [*] TCP/IP networking [*] IP: multicasting [*] IP: kernel level autoconfiguration [*] IP: BOOTP support
- 网上驱动配置
[*] 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 support [*] NFS client support for NFS version 3 [*] NFS client support for the NFSv3 ACL protocol extension [*] Root file system on NFS
---------------------------------------------------------------------
三、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,挂载方式可参考 NFS服务器配置。
