移植Android2.1（附获取freerunner 2.1 源码的方法）

一、获取freerunner2.1源码
目前freerunner的主线已经2.2(froyo)版本，当我们下载源码是指定branch为eclair时，发现已经编译不过了。究其原因是google官方已经将eclair部分代码移到eclair分支，而freerunner的eclair部分的代码依然留在master分支，导致两部分代码不一致而编译不过。好在git是一个强大的版本库管理软件，我们还是有办法拿到一个完整的freerunner2.1源码的。具体方法如下：
1）初始化版本库，使用默认的master分支
      repo init -u git://gitorious.org/android-on-freerunner/freerunner_platform_manifest.git
2）修改.repo/manifest.xml文件，将default的revision改为eclair，将freerunner部分项目的revision改为master。具体见附件
3）同步源码 ,执行repo sync，所需时间视网络环境而定
4）同步完源码后，还不能直接编译，因为目前freerunner的master分支目前已经是2.2的代码，我们需要利用git的回溯功能来时光倒流一下。步骤如下：
      1.将附件的goback.py拷贝到源码的根目录下
      2.执行 ./goback.py "2010-04-11 00:00"
5）经过以上的步骤后，我们已经可以得到一个完整的Android2.1源码了，但这时候的源码还没有解决mp3播放的问题，我们还需要将opencore的源码checkout到较新的版本
      进入 external/opencore，然后执行git checkout  ea1f1c41
6）编译源码
  manifest.xml.zip (3 K) 下载次数:453    goback.py.zip (1 K) 下载次数:369

二、移植Android2.1到mini2440
最近有点时间，尝试了移植Android on Freerunner开源项目所提供的Android2.1，还是使用之前的2.6.27内核，在上面做了一点少少的修改。
到目前为止，触摸屏已经校正，网络正常，声卡驱动用原来的OSS驱动，拨号有声音，但不能播放音乐，估计是libmediaplayer库的问题。

下面简单介绍一下移植的过程：
一、文件系统:
1.下载源文件：
建立源文件目录 mkdir ~/android_src
初始化repo  cd ～/android_src & repo init -u git://gitorious.org/android-on-freerunner/freerunner_platform_manifest.git (主线是2.1版本)
同步源文件 repo sync
整个过程会比较慢，可以同时开几个窗口来分别同步一些较大的project，例如 repo sync kernel，repo sync prebuilt，repo external/opencore，这样会快很多。
2.编译文件系统：
make
大概需要3─4个小时，这个跟机器的性能有关。
3.修改文件系统以适应Mini2440。
1)添加tslib触摸屏校正工具已经tslib所依赖的libc库和c++库，android系统本身使用的是Bionic c库。
2)添加buzybox，/myDev文件夹，/system/etc/shine文件夹
3)创建linuxrc启动脚本，/system/etc/myInit.rc初始化脚本，/system/etc/net.conf网络配置文件。
4)修改init.rc,去掉除mount tmpfs tmpfs /sqlite_stmt_journals size=4m之外所有的mount命令,并添加以下语句：
symlink /dev/snd/dsp /dev/eac 创建声卡的软连接
service console /bin/busybox sh //让系统使用buzybox的shell控制台
    console
service myInit /bin/busybox sh /system/etc/shine/myInit.rc //运行myInit.rc脚本，进行网络初始化等
    oneshot
5)将无线网卡的库文件复制的/system/etc/firmware下

二、内核
在原来2.6.27内核的基础下，做了以下的改动：
1.添加kasim大侠所提供的power supply class驱动，但是不能将该设备添加到smdk2440_devices[] __initdata下，否则不能用linuxrc启动脚本来启动系统。
2.配置内核是要选上Power management options中的Wake lock，Wake lock stats和Userspace wake locks，否则触摸屏会没有反应。
3.使SD卡能够被系统识别，必须要选上General setup-->Create deprecated sysfs files，并修改/system/etc/vold.conf文件，将media_path设置为/devices/platform/s3c2440-sdi/mmc_host/mmc0/
4.修改LCD驱动（drivers/video/s3c2410fb.c）以支持双重缓冲，android的显示系统需要双缓冲的支持。
5.修正触摸屏驱动中坐标方向错误的问题。

三、精简系统
64M内存对与Android系统来说实在是太少了，加载所有系统程序后，再打开其他程序会变得很慢。
为此可以删掉一些暂时用不到的系统软件如Phone，AlarmClock等（位于/system/app下），甚至可以只保留以下六个较为重要的系统程序：
LatinIME.apk，Launcher.apk，PackageInstaller.apk，Settings.apk，SettingsProvider.apk，UserDictionaryProvider.apk
然后再安装自己的软件，经过精简后，系统运行的效率会有很大的提高，个人感觉要比1.5版本系统更为流畅。



四、其他问题
系统休眠后不能唤醒，目前的解决办法是将系统设置成保持唤醒状态：
设置-->应用程序-->开发-->保持唤醒状态



在精简后的系统上安装最新的Android版QQ，运行很流畅，Android版QQ的UI也做得非常漂亮的说，下面是运行截图：



希望这些内容对大家用所帮助，也欢迎大家一起来分享自己的移植经验以及成果！

根文件系统：下载
内核镜像：下载
内核源码：下载

ps:
安装文件系统之前先把/system/etc/shine/pointercal删掉，否则触摸屏可能会不准。如果想重新校正触摸屏，也可以先删掉pointercal文件再重启系统。
为了能正确配置网络，还需要创建ifconfig和route的软连接，具体如下：
rm /system/bin/ifconfig
rm /system/bin/route
cd /bin
ln -s busybox ifconfig
ln -s busybox route

楼主啊，我用您的文件系统源码，用mkfs.jffs2 制作了jffs2映像文件 ，下载后只显示只企鹅，我用的是mini2440 64M 7inch 的LCD ，请问是我制作的文件系统映像有问题呢？还是？？ 有没有制作好的文件映像共享一下？
谢谢！！

版主啊，android默认的init.rc支持那种文件格式的文件系统？
我以jffs2格式的文件的话，需要怎么修改？

支持yafs映像格式吗？

版主啊，楼主提供的文件系统源文件需要生成可用在mini2440 64M的映像需要怎么做？

呵呵，问题比较低级，别笑话，刚入门，就是困难多多！！
多谢支持！！

非常感谢版主的指导，俺尝试了用SD卡启动，
按照 《SD卡启动系统步骤(可用于64M板)》说明，操作了，过程中在Ubuntu里面拷贝
android2.1-armv4t-rootfs.tar.gz 到SD卡里的FAT32里面并解压，解压过程中报出了很多
“无法创建到 “xxx文件”的符号连接：不允许的操作”
...

tar: ./myDev/TS0:无法mknod： 不允许的操作
tar: 由于前次错误，将以上次的错误状态退出



我还是强行的解压，然后在XP里的ghost做了镜像到SD卡里的linux ext3里去
下载到开发板上去，启动后，出现如下显示：

好的，谢谢，试一下，用解压的方式到 SD卡的第二个分区

版主啊，新问题啊：添加和不添加rootdelay参数 结果内核启动打印出来的错误不一样，是不是我内核配置有问题啊？

1.添加rootdelay的打印出来的命令行参数 linux command line is: "console=ttySAC0 root=179:2 rootdelay=3 init=/linuxrc"
2.没添加rootdelay的打印出来的命令行参数 linux command line is: "console=ttySAC0 root=179:2 init=/linuxrc"
