使用devkit8000移植android 21.docx

1、使用devkit8000移植android 21(Enhancd)使用devkit8000移植android 2.1 Eclair使用DevKit8000移植Android2.1 Eclair详细步骤。效果图如下。（使用devkit8000 + 4.3LCD样例）(更新主题之后)下面的步骤将告诉你如何建立你的开发环境，以及交叉编译等。一jdk 1.5的准备你的开发机（Ubuntu）需要安装jdk1.5，如果是其它版本比如1.6，我建议你还是使用jdk1.5版本。1将这两行添加到你的/etc/apt/sources.list中deb jaunty multiversedeb jaunty-upd

2、ates multiverse2更新你的源并安装Sun JDK 1.5:$ sudo apt-get update$ sudo apt-get install sun-java5-jdk3为了使你的系统使用Java 5，你应该做一定的选择配置$ sudo update-alternatives -config java4选择使用java-1.5.0-sun二下载源码这里仍然使用git下载，并使用repo工具来同步1安装git工具，如果想对git工具详细的了解，请查看使用git建立远程仓库，让别人git clone下来一文。$ sudo apt-get install git-core2安装re

3、po工具$ curl -o /bin/repo http:/android.git.kernel.org/repo$ chmod a+x /bin/repo3下载源码Where BRANCH_NAME is:* beagle-eclair - for Eclair version of android* beagle-donut - for Donut version0fandroid* beagle-cupcake - for Cupcake version of android$ mkdir BRANCH_NAME$ cd BRANCH_NAME$ repo init -u git:/gi

4、torious.org/0xdroid/manifest.git -b BRANCH_NAME$ repo sync三编译你的android版本1将这些添加（新建）buildspec.mk文件中$ echo TARGET_PRODUCT := devkit8000 buildspec.mk$ echo INSTALL_PREBUILT_DEMO_APKS := true buildspec.mk$ make -j22一旦编译成功，检查你的成果。* out/target/product/devkit8000/root/* out/target/product/devkit8000/system/

5、* out/target/product/devkit8000/system.img3安装uboot制作工具$sudo apt-get install uboot-mkimage4编译内核（和你的BRANCH_NAME平级目录）$ cd .$ git clone git:/gitorious.org/0xlab-kernel/kernel.git$ cd kernel$ git checkout -b kernel_omap3 origin/omap3-2.6.32$ make ARCH=arm devkit8000_defconfig # build for devkit80005 buil

6、d kernel image along with kernel modules:$ make ARCH=arm CROSS_COMPILE=./beagle-eclair/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/arm-eabi- uImage$ make ARCH=arm CROSS_COMPILE=./beagle-eclair/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/arm-eabi- modules四准备移植现在你的工作基本完成！1准备一张SD卡，并建立格式为vfat的第一

7、分区，大小100M。关于如何制作请参见，本网站：实例解说 fdisk 使用方法2在第一分区你需要这些文件：(1)out/target/product/beagleboard/system.img但需要改名为system.img - system.ubi(2)arch/arm/boot/uImage同样需要改名uImage - kernel.bin(3)建立install.conf文件，并添加如下内容installerKERNEL_IMAGE= kernel.binROOTFS_IMAGE= system.img# Uncomment the following to reflash the b

8、oot loader# U_BOOT_IMAGE= flash-uboot.bin# Uncomment the following to install to SD card# INSTALL_TO_SD = y# Uncomment the following to grab images from network# NET_INSTALL=y# IPADDRESS=192.168.0.202# REMOTE_KERNEL_IMAGE=http:/192.168.0.201/0xkernel-beagle.bin# REMOTE_ROOTFS_IMAGE=http:/192.168.0.2

10、关于第4.5这两个必需品，我暂时不在该页面提供下载地址，如有需要，请跟贴联系【www.ourunix.org】站长会尽快回复你的o五适配和移植1第四步所有材料都有有了，请按照下面步骤测试，你肯定被编译的时候已经搞的精疲力尽了，呵呵，下面是犒劳自己的时候了。2刚才让你添加的install.conf，你需要取消注释U_BOOT_IMAGE这一行；并且选择你的显示器尺寸，简单的英文应该可以看懂吧！3将你的SD卡取下并插入到你的DEVKit8000中去，并重新启动。4打开你的超级终端（minicom）或者其它；跟着这些代码走：mmcinitfatload mmc 0 80300000 flash-ub

11、oot.bingo 80300000这个时候你可以看到你的DevKit8000的显示器有一个安装图形工具的进步条了，不要急，你快要成功了哦。等进度条完成boot片刻之后，根据你的终端显示，你关掉你的板子，最后拔掉SD卡，重新启动。当然你的东西已经完全烧到NandFlash中了。是不是进去拉。GoodLuck！Precondition: Sun JDKYou would need Sun JDK version 1.5 to build Donut. However, Sun JDK version 1.5 is known to be EOL (End-Of-Line), and Ubuntu

12、 Linux 9.10 no longer ships with sun-java5-jdk.If you are using Ubuntu Linux 9.10, just add these two line in file /etc/apt/sources.list:deb karmic-updates multiversedeb-src karmic-updates multiverseand install Sun JDK 1.5:$ sudo apt-get update$ sudo apt-get install sun-java5-jdkTo set the system to

13、 use Java 5, you need to update your java alternatives by running$ sudo update-alternatives -config javaChoose java-1.5.0-sun and it should be done.Precondition: git and repoBefore you download the source, you will needgitandrepotools.On an Ubuntu 9.04 host, you can do the following:Getting git:$ su

14、do apt-get install git-coreGetting repo: (make sure /bin is included in $PATH)$ curl https:/dl- /bin/repo$ chmod a+x /bin/repoFor reference details about Repo, seeUsing Repo and Git.Get 0xdroid sourceDownload the 0xdroid source code:$ mkdir beagle-donut$ cd beagle-donut$ repo init -u git:/gitorious.

15、org/0xdroid/manifest.git -b BRANCH_NAME$ repo syncWhere BRANCH_NAME is: beagle-eclair - for Eclair version of 0xdroid beagle-donut - for Donut version 0f 0xdroid beagle-cupcake - for Cupcake version of 0xdroidAlternatively, use faster git mirror if encountering the problem during repo sync:$ repo in

16、it -u git:/gitorious.org/0xdroid/manifest.git -b BRANCH_NAME -m mirror.xml$ repo sync Build 0xdroid from sourceSetup beagleboard specific configurations and enabled components:$ echo TARGET_PRODUCT := beagleboard buildspec.mk$ echo INSTALL_PREBUILT_DEMO_APKS := true buildspec.mkNOTE: If you want to

17、build DevKit8000 instead of Beagleboard, replace the context TARGET_PRODUCT := beagleboard to TARGET_PRODUCT := devkit8000.Build as expected:$ makeOnce successfully built, the generated root file system is here: out/target/product/beagleboard/root/ out/target/product/beagleboard/system/And the corre

18、spondingUBIFSsystem image for NAND flash: out/target/product/beagleboard/system.imgFor advanced usage, fetch and build Linux kernel from scratch. You need uboot-mkimage installed in host machine:# apt-get install uboot-mkimageThe instructions for building kernel image:$ cd .$ git clone git:/gitoriou

19、s.org/0xlab-kernel/kernel.git$ cd kernel$ git checkout -b kernel_omap3 origin/omap3-2.6.32Select proper default kernel configuration to match the machine. Beagleboard:$ make ARCH=arm omap3_beagle_defconfigor DevKit8000:$ make ARCH=arm devkit8000_defconfig # build for devkit8000Finally, build kernel

20、image along with kernel modules:$ make ARCH=arm CROSS_COMPILE=./beagle-eclair/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/arm-eabi- uImage$ make ARCH=arm CROSS_COMPILE=./beagle-eclair/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/arm-eabi- modulesFlash images to targetAfter this long building

21、process, we should get our own Android kernel and system images. Then we can usehappy Installerand then do a SD card booting. Here are the steps as below: Format the first partition over than 100MB with VFAT on a SD card. Download the installeruImage.bin Rename out/target/product/beagleboard/system.

22、img to android-beagle.ubi Rename arch/arm/boot/uImage to 0xkernel-beagle.bin Copy above three files into the first partition of SD/MMC card Plug the SD card in Beagle board SD slot and restart the Beagleboard Wait for UI installer over. The installer would perform NAND flashing and u-boot environment setup. Unplug SD card from the Beagleboard and reboot Enjoy!
