开发平台：

RedHat 9.0 ＋ mini2440开发板

使用内核版本类型：

linux-2.6.25-android-1.0_

下载地址：/p/android/downloads/list

交叉编译器：

2

下载地址：

/sgpp/lite/arm/portal/release642或者直接复制下面地址

/sgpp/lite/arm/portal/package3686/public/arm-none-eabi/2

第一部分：内核映像及文件系统介绍

1、zImage：andriod内核映像文件。支持触摸屏（目前没有校屏程序，点击不太准），支持nfs文件系统启动，支持RTC(可以正确显示google时钟)，支持DM9000网卡，支持yaffs文件系统，电源管理等。

2、nfs_root_：nfs方式启动文件系统，可以看到很绚丽的google大钟和google浏览器。

3、final_：内核配置文件（可以自己用命令mv final config .config 放到内核下进行编译）。

（为何不提供yaffs文件系统而采用NFS启动方式：主要原因是mini2440开发板提供的nand

flash太小，只有64M空间，这里需要至少80M的空间）

第二部分：使用说明

（注意：开发环境和redhat9.0系统的安装大家可以参考mini2440开发板手册。这里给出一些新的修改。）

使用方法：

（以下步骤1－4在windows下操作，5－7在linux下操作）

1、打开DNW工具，切换到norflash启动方式,给开发板上电,启动supervivi的菜单。如下图所示：

2、选择“k”，（[k] Download linux kernel），然后通过usb下载内核zImage(就是上面的zImage)。

3、选择“b”（[b] Boot the system），启动内核看看是否可以正确引导内核。

出现下面内容表示已经正确引导了。

。。。。。。

[s] Set the boot parameters

[t] Print the TOC struct of wince

[u] Backup NAND Flash to HOST through USB(upload)

[r] Restore NAND Flash from HOST through USB

[q] Goto shell of vivi

Enter your selection: b

Root-NFS: Unable to get nfsd port number from server, using default

Looking up port of RPC 100005/1 on 192.168.1.100

4、设置nfs启动参数

首先复位mini2440开发板，回到supervivi的菜单, 选择“s”，可以到设置启动

参数的菜单（如下图所示）。

继续选“s”，设置参数。

出现下面界面：

输入修改启动命令行，linux_cmd_line

回车后，输入"console=ttySAC0 root=nfs nfsroot=192.168.1.100:/nfs_root

ip=192.168.1.70 init=/init”。

回到刚刚设置菜单下面选择“w”,写入修改后的参数。

这里可以用”v”,查看修改是否成功和正确。

5、修改nfs设置文件/etc/exports

/nfs_root *(rw,sync,no_root_squash)

6、设置主机IP地址

地址：192.168.1.100 子网掩码：255.255.255.0 默认网关：255.255.255.255

7、nfs_root_拷贝到/目录下,解压tar zxvf nfs_root_

这样在根目录下就存在一个nfs_root目录，里面就是andriod启动所需要的文件系统。最后在终端中输入命令 exportfs –r命令更新/etc/exports(在提示找不到文件系统时，试试这个命令)。
