S3C2440嵌入式Linux下网卡DM9000E移植(2)

三、在内核中增加对网卡DM9000的配置
在内核目录下执行“make menuconfig”命令进行如下的配置：
Device Drivers--->
[*]Network device support--->
[*]Ethernet(10 or 100Mbit)--->
<*>DM9000 support
[*]Networking support--->
Networking options--->
<*>TCP/IP networking
<*>IP:kernel leel autoconfiguration
//增加对nfs的支持
File systems--->
[*]Networking File Systems--->
<*>NFS client support
[*]NFS client support for NFS version 3
[*]NFS client support for the NFSv3 ACL protocol extension
[*]Boot file system on NFS
[*]NFS server support
四、修改根文件系统启动脚本rcS
在根文件etc/init.d/rcS文件中添加如下：
echo "network interface"
/sbin/ifconfig lo 127.0.0.1
/sbin/ifconfig eth0 192.168.1.230 up
route add default gw 192.168.1.1
五、测试和修改
至此，将修改过的内核和根文件系统下载到mini2440开发板，启动时出现如下信息：
----------munt all----------------
network interface
dm9000 dm9000.0: WARNING: no IRQ resource flags set.
eth0: link up, 10Mbps, half-duplex, lpa 0x0021

注：在挂载网络文件系统时先要在Linux系统下设置共享目录才能在从开发板挂载该目录，这里已经在虚拟机下RedHat9.0系统中的/opt下设置了共享目录nfs，虚拟机的ip为192.168.1.103，故通过mount -t nfs -o nolock 192.168.1.103:/opt/nfs /mnt命令挂载。
