linux-2.6.35内核移植—网卡驱动的移植
一、移植环境:
1、 Ubuntu 10.10发行版
2、 u-boot.bin http://download.csdn.net/detail/baby_afu/4412826
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
