Some Chinese customers using i.MX series SoC maybe encounter some issues when they download android , u-boot & kernel source code by 'git' command, the following steps will show customer how to get them:
1. Getting repo
--No.1 methord
# cd ~
# mkdir myandroid
# mkdir bin
# cd bin
# git clone git://aosp.tuna.tsinghua.edu.cn/android/git-repo.git/
<if git failed, use : git clone https://aosp.tuna.tsinghua.edu.cn/android/git-repo.git/>
# cd git-repo
# cp ./repo ../
--No.2 methord
# cd ~
# mkdir bin
# curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
# chmod a+x ~/bin/repo
[Note]Customers can select one of above to get "repo"
2. Modifying repo File
Open ~/bin/repo file with 'gedit' and Change google address
From
REPO_URL = 'https://gerrit.googlesource.com/git-repo'
To
REPO_URL = 'git://aosp.tuna.tsinghua.edu.cn/android/git-repo'
like following:
## repo default configuration
##
REPO_URL = 'git://aosp.tuna.tsinghua.edu.cn/android/git-repo'
REPO_REV = 'stable'
3、Setting email address
# cd ~/myandroid
# git config --global user.email "weidong.sun@nxp.com"
# git config --global user.name "weidong.sun"
[ Email & Name should be yours]
4、Getting manifest
# ~/bin/repo init -u https://aosp.tuna.tsinghua.edu.cn/android/platform/manifest -b android-5.1.1_r1
# cd ~/myandroid/.repo
# gedit manifest.xml
Then change the value of fetch to " git://aosp.tuna.tsinghua.edu.cn/android/ ", like following:
<manifest>
<remote name="aosp"
fetch="git://aosp.tuna.tsinghua.edu.cn/android/" />
<default revision="refs/tags/android-5.1.1_r1"
......
[Note] android-5.1.1_r1 is version of branch,customer can change it to another.
5、# ~/bin/repo sync
[Note] During runing repo sync, maybe errors will occur like the following:
......
* [new tag] studio-1.4 -> studio-1.4
error: Exited sync due to fetch errors
Then 'repo sync' exits. But don't worry about it, continue to run the command please !
" ~/bin/repo sync", downloading source code will be continous.
6、Getting Cross Compiler
# cd ~/myandroid/prebuilts/gcc/linux-x86/arm
# git clone https://aosp.tuna.tsinghua.edu.cn/android/platform/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6
# cd arm-eabi-4.6
# git checkout android-4.4.3_r1
7、Getting linux kernel source code
Probably, customer can't normally get linux kernel by using "git clone" command, she can download it directly from the following weblink:
http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/
At first, create a temperary directory, then download kernel into the directory. see following steps:
# cd ~ /Downloads
# mkdir linux-kernel
Atfer downloading l5.1.1_2.1.0-ga.tar.gz, use 'tar zxvf l5.1.1_2.1.0-ga.tar.gz' command to decompress it.
Then you can find a subdirectory name " l5.1.1_2.1.0-ga" is created, linux source code is in the directory, we should copy all files in the directory to ~/myandroid/kernel_imx/
# cd ~/myandroid
# mkdir kernel_imx
# cd kernel_imx
# cp -a ~ /Downloads/linux-kernel/l5.1.1_2.1.0-ga ./
8、Getting uboot source code
Probably, customer can't normally get linux kernel by using "git clone" command, she can download it directly from the following weblink:
http://git.freescale.com/git/cgit.cgi/imx/uboot-imx.git/
We can use similar way to that of linux kernel to get u-boot source code:
# cd ~ /Downloads
# mkdir u-boot
Download l5.1.1_2.1.0-ga.tar.gz file, and save it in ~ /Downloads/ u-boot, then decompress it, then u-boot source code will be in ~ /Downloads/ u-boot / l5.1.1_2.1.0-ga/, we should copy all file in the path to ~/myandroid/bootable/bootloader/uboot-imx/
# cd ~/myandroid/bootable/bootloader
# mkdir uboot-imx
# cd uboot-imx
# cp -a ~ /Downloads/u-boot/l5.1.1_2.1.0-ga/* ./
9、Patch android BSP source code
android_L5.1.1_2.1.0_consolidated-ga_core_source.gz is the name of patch. Run following command to patch android.
# copy android_L5.1.1_2.1.0_consolidated-ga_core_source.gz /opt/
# tar zxvf android_L5.1.1_2.1.0_consolidated-ga_core_source.gz
# cd /opt/ android_L5.1.1_2.1.0_consolidated-ga_core_source/code/
# tar zxvf L5.1.1_2.1.0_consolidated-ga.tar.gz
# cd ~/myandroid
# source /opt/ android_L5.1.1_2.1.0_consolidated-ga_core_source/code/ L5.1.1_2.1.0_consolidated-ga/ and_patch.sh
# help
# c_patch /opt/ android_L5.1.1_2.1.0_consolidated-ga_core_source/code/ L5.1.1_2.1.0_consolidated-ga/ imx_L5.1.1_2.1.0-ga
If everything is OK, the following logs will display on console:
**************************************************************
Success: Now you can build the Android code for FSL i.MX platform
**************************************************************
10、Patch Freescale extended feathures code
Please refer to chapter 3.3 of Android_User's_Guide.pdf to patch another 2 files:
(1) android_L5.1.1_2.1.0_consolidated-ga_omxplayer_source.gz
(2) android_L5.1.1_2.1.0_consolidated-ga_wfdsink_source.gz
[Note]
As for other steps, such as compiling etc, please refer to Android_User's_Guide.pdf that released by NXP.
