01. 编译内核

1.1 解压内核源码

[root@itcast tools]# tar -xjvf linux-3.5_analyse.tar.bz2

1.2 配置内核

[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 关闭TtrustZone

[root@itcast linux-3.5_analyse]# vim .config +485
注释485行
485 #CONFIG_ARM_TRUSTZONE is not set #=y

1.4 编译源码

[root@itcast linux-3.5_analyse]# make -j4

02. 安装dnw工具

2.1 解压dnw工具

[root@itcast tools]# tar -xzvf dnw-linux.tar.gz

2.2 编译

[root@itcast tools]# cd dnw-linux
[root@itcast dnw-linux]# make

2.3 安装

[root@itcast dnw-linux]# make install
make -C /lib/modules/`uname -r`/build M=`pwd`/src/driver modules
make[1]: Entering directory `/usr/src/kernels/2.6.32-431.el6.x86_64'
  Building modules, stage 2.
  MODPOST 1 modules
make[1]: Leaving directory `/usr/src/kernels/2.6.32-431.el6.x86_64'
make -C src/dnw
make[1]: Entering directory `/home/tools/dnw-linux/src/dnw'
make[1]: “dnw”是最新的。
make[1]: Leaving directory `/home/tools/dnw-linux/src/dnw'
make -C src/dnw install
make[1]: Entering directory `/home/tools/dnw-linux/src/dnw'
cp dnw /usr/bin
make[1]: Leaving directory `/home/tools/dnw-linux/src/dnw'
make -C /lib/modules/`uname -r`/build M=`pwd`/src/driver modules_install
make[1]: Entering directory `/usr/src/kernels/2.6.32-431.el6.x86_64'

cp dnw.rules /etc/udev/rules.d/
depmod
[root@itcast dnw-linux]#

2.4 测试

[root@itcast dnw-linux]# dnw
Usage: dwn [-a load_addr] <filename>
Default load address: 0x57e00000
[root@itcast dnw-linux]#

03. 安装Android_tools

3.1 解压

[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 将可执行文件拷贝到/usr/local/bin目录中

[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]#

04. 烧写Android系统

4.1 查看分区

# minicom端
DengJin # fdisk -p 0

partion #    size(MB)     block start #    block count    partition_Id 
DengJin #

4.2 分区

# minicom
DengJin # fdisk -c 0 320 806 518
fdisk is completed

partion #    size(MB)     block start #    block count    partition_Id 
   1          5788          3521760        11855580          0x0C 
   2           326           136620          667920          0x83 
   3           807           804540         1654620          0x83 
   4           518          2459160         1062600          0x83 
DengJin #

4.3 格式化分区

# minicom
DengJin # fatformat mmc 0:1
Start format MMC&d partition&d ...
Partition1: Start Address(0x35bce0), Size(0xb4e6dc)
size checking ...
Under 8G
write FAT info: 32
Fat size : 0x2d39
Erase FAT region................................................................................
Partition1 format complete.

4.4 烧写Android镜像

images\Superboot4412.bin        Bootloader
images\Android\zImage           Android 内核
images\Android\ramdisk-u.img    Android 根分区映象
images\Android\system.img       Andorid 系统分区映象
image\Android\userdata.img      Andorid Data 分区映象
images\FriendlyARM.ini          系统烧写配置文件

# 在minicom中:
DengJin #fastboot

烧写内核

[root@itcast boot]# pwd
/home/tools/linux-3.5_analyse/arch/arm/boot
[root@itcast boot]# ls
bootp  compressed  dts  Image  install.sh  Makefile  zImage


[root@itcast boot]# fastboot flash kernel zImage

OKAY [  1.078s]
writing 'kernel'...
OKAY [  0.376s]
finished. total time: 1.530s
[root@itcast boot]#

格式化data分区和cache分区

[root@itcast boot]# fastboot -w
erasing 'userdata'...

[root@itcast boot]#

烧写根分区映像

[root@itcast Android]# fastboot flash ramdisk  ramdisk-u.img 
sending 'ramdisk' (703 KB)...
OKAY [  0.185s]
writing 'ramdisk'...
OKAY [  0.055s]

[root@itcast Android]#

烧写系统分区

[root@itcast Android]# fastboot flash system system.img

设置启动参数

DengJin # set bootargs console=ttySAC0,115200n8 androidboot.console=ttySAC0 lcd=S70 ctp=2
DengJin # save
Saving Environment to SMDK bootable device...
done
DengJin # reset

等会Android系统就启动了。

06. 问题解决

6.1 问题一：fastboot执行失败，动态库找不到

[root@itcast bin]# fastboot
fastboot: error while loading shared libraries: libstdc++.so.6: 
cannot open shared object file: No such file or directory

解决办法

[root@itcast bin]# yum install libstdc++.i686
