一, 从Git仓库中下载iMx51-android源程序
(1) 下载repo工具:
1, mkdir ~/android-imx
2, cd ~/android-imx
3, curl http://android.git.kernel.org/repo > ./repo
4, chmod a+x ./repo
说明:如果系统环境中存在repo工具,则3,4步可以省略。
(2)下载iMx51-android code
5, repo init -u git://192.168.10.225/imx/arm/platform/manifest.git
6, cd .repo/manifests
7, git branch -a
8, git checkout origin/froyo-imx -b froyo-imx
9, cd ~/android-imx
10, repo sync
说明:下载完之后,在目录 ~/android-imx下,包括了kernel_imx,和uboot-imx
二,Git操作
(1) 提交修改:
1, git checkout korg/froyo -b froyo
2, git commit -a -s -m "所提交内容的描述"
3, git push
(2) 更新git服务器的内容到本地。
1, git pull
或
2, cd ~/android-imx
repo sync
(3) 常用其它相关的命令:
1, git-log 查看修改日志
2, git-status 查看状态
3, git diff 比较不同
三,编译
(1) 设置编译环境:(imx-android-r9.2.tar.gz工具可从233上获得)
1, export ARCH=arm
2, export CROSS_COMPILE=/opt/gcc-4.1.2-glibc-2.5-nptl-3/arm-none-linux-gnueabi/bin/arm-none-linux-gnueabi-
3, export PATH=/opt/gcc-4.1.2-glibc-2.5-nptl-3/arm-none-linux-gnueabi/bin:$PATH
(2) 编译Uboot-imx
1,cd ~/android-imx/bootable/bootloader/uboot-imx
2,make distclean
3,make mx51_bbg_android_config
4,make
5,sudo dd if=./u-boot.bin of=./u-boot-no-padding.bin bs=1024 skip=1
6,sync
(3) 编译kernel-imx
export PATH=~/android-imx/bootable/bootloader/uboot-imx/tools:$PATH
1,cd ~/android-imx/kernel_imx
2,make imx5_android_defconfig
3,make uImage
4,cd ~/android-imx/kernel_imx/arch/arm/boot
5,~/android-imx/bootable/bootloader/uboot-imx/tools/mkimage -A arm -O linux -T kernel -C none -a 0x90008000 -e 0x90008000 -n "Android Linux Kernel" -d ./zImage ./uImage
(4) 编译android
1,cd ~/android-imx
2,make PRODUCT-imx51_bbg-eng 2>&1 | tee build_imx51_bbg_android.log
3,cd android-imx/out/target/product/imx51_bbg
4,~/android-imx/bootable/bootloader/uboot-imx/tools/mkimage -A arm -O linux -T ramdisk -C none -a 0x90308000 -n "Android Root Filesystem" -d ./ramdisk.img ./uramdisk.img
