教程:
一、配置linux内核:
进入打过at91补丁的linux2.6内核源代码树的根目录
make menuconfig进入内核配置程序。
1.
Networking --->
Networking options --->
[*] IP: kernel level autoconfiguration
[*] IP: DHCP support
[*] IP: BOOTP support
[*] IP: RARP support
2.
Device Drivers --->
Block devices --->
<*> Network block device support
3. 选中Device Drivers --->
Ethernet (10 or 100Mbit) --->
<*> Atmel MACB support
[*] Atmel MACB TX buffers in internal SRAM
4. 选中File systems --->
Network File Systems --->
<*> NFS client support
[*] Provide NFSv3 client support
[*] Provide client support for the NFSv3 ACL protocol extension
[*] Provide NFSv4 client support (EXPERIMENTAL)
[*] Root file system on NFS
5.
重新编译内核
make uImage
cp linux-2.60/arch/arm/boot/uImage /
二、烧写内核
开机回车进入Uboot。在命令编写命令烧写内核。
Hit any key to stop autoboot: 0
U-Boot>
U-Boot> nand erase 0x100000 0x200000
NAND erase: device 0 offset 0x100000, size0x200000
Erasing at 0x2e0000 -- 100% complete.
OK
U-Boot> tftp 0x22000000 uImage
macb0: Starting autonegotiation...
macb0: Autonegotiation complete

done
Bytes transferred = 1804256 (1b87e0 hex)
nand write 0x2200 0000 0x10 0000 0x20 0000 将内核烧入NandFlash中
三、 主机开启NFS服务 //// 写成脚本,方便调用
#!/bin/bash
ifconfig eth0 192.168.1.101
/etc/rc.d/init.d/portmap restart
/etc/rc.d/init.d/nfs restart
#!/bin/sh
mount -t nfs 192.168.1.101:/fs /mnt -o nolock
///// 本地测试 NFS服务是否开启,/fs为自定义的NFS根目录
echo "nfs ok!"
四、主机关闭防火墙
# lokkit //// 回车进入后, 禁用防火墙
#service iptables stop //// 停止防火墙服务
五、启动u-boot配置启动参数:
setenv bootargs
root=/dev/nfs rw console=ttyS0,115200 mem=16M nfsroot=192.168.1.101:/fs
ip=192.168.1.10:192.168.1.101:192.168.1.1:255.255.255.0::eth0:off
///// 假设 主机IP为 192.168.1.101
然后保存参数:saveenv
六、 开机进入NFS
