[root@itcast tools]# tar -xjvf linux-3.5_analyse.tar.bz2
1.2 配置內核
[root@itcast linux-3.5_analyse]# make clean
[root@itcast linux-3.5_analyse]# cp tiny4412_android_defconfig .config
[root@itcast linux-3.5_analyse]#
1.3 關閉TtrustZone
[root@itcast linux-3.5_analyse]# vim .config +485
註釋485行
485 #CONFIG_ARM_TRUSTZONE is not set #=y

02. 安裝dnw工具
2.1 解壓dnw工具
[root@itcast tools]# tar -xzvf dnw-linux.tar.gz
2.2 編譯
[root@itcast tools]# cd dnw-linux
[root@itcast dnw-linux]# make
2.3 安裝
[root@itcast dnw-linux]# make install
make -C /lib/modules/`uname -r`/build M=`pwd`/src/driver modules

2.4 測試
[root@itcast dnw-linux]# dnw
Usage: dwn [-a load_addr] <filename>
Default load address: 0x57e00000
[root@itcast dnw-linux]#
03. 安裝Android_tools
3.1 解壓
[root@itcast tools]# tar -xzvf android_tools.tgz
usr/local/bin/fastboot
usr/local/bin/adb
usr/local/bin/minigzip
usr/local/bin/mkbootfs
usr/local/bin/mkimage
[root@itcast tools]#
3.2 將可執行文件拷貝到/usr/local/bin目錄中
[root@itcast tools]# cd usr/local/bin/
[root@itcast bin]# ls
adb fastboot minigzip mkbootfs mkimage
[root@itcast bin]# cp * /usr/local/bin/
[root@itcast bin]#

05. 問題解決
6.1 問題一：fastboot執行失敗，動態庫找不到
[root@itcast bin]# fastboot
fastboot: error while loading shared libraries: libstdc++.so.6:
cannot open shared object file: No such file or directory
解決辦法
[root@itcast bin]# yum install libstdc++.i686
