2440+2.6.33 DM9000移植（四）

分类： 嵌入式

2011-04-05 19:15:04

1.linux内核的DM9000网卡的移植完全和   [连载]2440+30.4 DM9000-platform（四）  一样，
   从 第一步 到 第六步 都是 和 2440+30.4 DM9000-platform

2. 文件系统的建立 参考TQ10年文件系统移植手册

   1.修改文件系统的 “/etc/init.d/rcS”,添加如下内容
 
  1. ifconfig lo 127.0.0.1   # 设置本地会还设备IP地址，缺省值
  2. net_set&                # 调用网络配置文件
 
   2.在文件系统的 “/sbin”目录下新建可执行文件 “net_set”,内容如下
  1. #!/bin/sh

  3. echo Try to bring eth0 interface up ...>/dev/ywx-serial0

  5. source /etc/nettype.conf
  6. if [ -f /etc/net.conf ] ; then
  7. source /etc/net.conf

  9. if [ $NETTYPE -eq 1 ] ; then
  10. ifconfig eth0 down
  11. ifconfig eth0 hw ether $MAC
  12. echo ifconfig eth0 hw ether $MAC >/dev/ywx-serial0
  13. ifconfig eth0 $IPADDR netmask $NETMASK up
  14. echo ifconfig eth0 $IPADDR netmask $NETMASK up >/dev/ywx-serial0
  15. route add default gw $GATEWAY
  16. echo add default gw $GATEWAY >/dev/ywx-serial0
  17. elif [ $NETTYPE -eq 2 ] ; then
  18. source /etc/wifi.conf
  19. ifconfig eth0 down
  20. ifconfig wlan0 $IPADDR netmask $NETMASK up
  21. echo ifconfig wlan0 $IPADDR netmask $NETMASK up >/dev/ywx-serial0
  22. route add default gw $GATEWAY
  23. echo route add default gw $GATEWAY >/dev/ywx-serial0
  24. iwconfig wlan0 essid "$NETNAME" key "$PASSWORD"
  25. echo iwconfig wlan0 essid "$NETNAME" key "$PASSWORD" >/dev/ywx-serial0
  26. fi
  27. else

  29. ifconfig eth0 hw ether 10:23:45:67:89:ab
  30. ifconfig eth0 192.168.1.6 netmask 255.255.255.0 up
  31. route add default gw 192.168.1.2
  32. echo ifconfig eth0 hw ether 10:23:45:67:89:ab >/dev/ywx-serial0
  33. echo ifconfig eth0 192.168.1.6 netmask 255.255.255.0 up >/dev/ywx-serial0
  34. echo route add default gw 192.168.1.2 >/dev/ywx-serial0
  35. fi

  37. echo Done > /dev/ywx-serial0

   注意： 我这里 都是 ywx-serial0  这里使用第一个串口
原因如下：
    2.1.在tq自己制作好的文件系统下 ，sbin/net_set
                       >/dev/tq2440_serial0
      drivers/serial/samsung.c
      第888 行 .devname=tq2440_serial
  
    2.2.所以，仿照tq的做法，   sbin/net_set
                      >/dev/ywx-serial0
      drivers/serial/samsungd.
      第888行，.devname=ywx-serial
   

 
3.在文件系统 “/etc/”目录下新建 net.conf  存放网络配置的信息
  1. IPADDR=192.168.1.6
  2. NETMASK=255.255.255.0
  3. GATEWAY=192.168.1.2
  4. MAC=10:23:45:67:89:ab

  当我们需要修改网卡的IP等的时候，只需要修改 “/etc/net.conf”文件的内容执行一下
net_set 命令即可。

到这里，我们设置完文件系统了，mkyaffs2imag root-2.6.33 roo-2.6.33.bin 就可以了下载到板子了


4.下载启动过程中，出现一个错误
  1. /sbin/net_set: source: line 5: can't open '/etc/nettype.conf
  2. Please press Enter to activate this console.
    [root@yuweixian /]# ifconfig
修改如下：
   1.在文件系统新建  /etc/nettype.conf     
  1. CDMAUSE=0
  2. NETTYPE=1
  2.或者 直接复制 tq 文件系统 /etc/nettype.conf  到自己的文件系统下


5. 做完 上面的，开发板连上网线，就可以了
   注意：这里PC主机 和 开发板 要使用相同的网段 如：192.168.1.6  192.168.1.7

   启动，OK!!!!!!!!
