将Android移植到FS2410开发板上

1．Android已经可以通过NFS在FS2410开发板上运行

二、目前缺陷

1．触摸屏没有校准

2．Android中时钟停止，结束zygote进程，系统重启，时钟更新，但再次停止不动

3．串口无法与GPRS模块通讯

三、移植步骤

一、移植Android内核到FS2410开发板上

1、从de.google.com/p/android/downloads/list">http://code.google.com/p/android/downloads/list上下载linux-2.6.25-android-1.0_r1.tar.gz

2、将内核解压到用户目录，如/home/wangan/kernel.git

3、进入kernel.git文件夹，如cd ~/kernel.git/

4、修改arch/arm/plat-s3c24xx/common-smdk.c文件中的nand flash分区设置，如gedit arch/arm/plat-s3c24xx/common-smdk.c

修改static struct mtd_partition smdk_default_nand_part[]结构体为：

static struct mtd_partition smdk_default_nand_part[] = {

[0] = {

.name = "Boot Agent",

.size = SZ_256K,

.offset = 0,

},

[1] = {

.name = "Linux Kernel",

.offset = SZ_256K,

.size = SZ_2M - SZ_256K,

},

[2] = {

.name = "File System",

.offset = SZ_2M,

.size = SZ_32M - SZ_2M,

},

[3] = {

.name = "Other",

.offset = SZ_32M,

.size = SZ_32M,

}

};

5、在http://www.codesourcery.com/gnu_toolchains/arm/portal/release644网站上下载IA32 GNU/Linux TAR。

6、将文件解压到用户目录，如/home/wangan/arm-2008q3

7、进入arm-2008q3/bin文件夹，如cd ~/arm-2008q3/bin/

8、添加当前路径进入环境变量，如export PATH=$PWD:$PATH，或修改~/.bashrc文件并重新登录

9、进入内核文件夹，如cd ~/kernel.git/

10、修改Makefile文件，如gedit Makefile

更改ARCH和CROSS_COMPILE

#ARCH ?= $(SUBARCH)

ARCH ?= arm

#CROSS_COMPILE ?= arm-eabi-

CROSS_COMPILE ?= arm-none-eabi-

11、从华清远见Linux-2.6.8.1内核压缩包中提取.config文件（注意：config前面有个“.”）放入kernel.git文件夹

12、运行make menuconfig

(1) 确保System Type ---> ARM system type ()中的内容为Samsung S3C2410, S3C2412, S3C2413, S3C2440, S3C2442, S3C2443

(2) 确保System Type ---> S3C2410 Machines ---> [*] SMDK2410/A9M2410被勾选

(3) 取消选择与Goldfish相关的内容

Device Drivers ---> Character devices ---> < > Goldfish TTY Driver

Device Drivers ---> Power supply class support ---> < > Goldfish battery driver (NEW)

Device Drivers ---> Real Time Clock ---> < > GOLDFISH (NEW)

Device Drivers ---> Graphics support ---> Support for frame buffer devices ---> < > Goldfish Framebuffer

(4) 选择S3C2410 LCD相关的内容

Device Drivers ---> Graphics support ---> Support for frame buffer devices ---> <*> S3C2410 LCD framebuffer support

Device Drivers ---> Graphics support ---> [*] Bootup logo ---> [*] Standard black and white Linux logo

Device Drivers ---> Graphics support ---> [*] Bootup logo ---> [*] Standard 16-color Linux logo

Device Drivers ---> Graphics support ---> [*] Bootup logo ---> [*] Standard 224-color Linux logo

(5) 选中Android内核必须选项

Kernel Features ---> [*] Use the ARM EABI to compile the kernel

General setup ---> [*] Use full shmem filesystem

General setup ---> [*] Enable Androids Shared Memory Subsystem

System Type ---> [*] Support Thumb user binaries

Device Drivers ---> Android ---> [*] Android log driver

Device Drivers ---> Android ---> <*> Binder IPC Driver

(6) 尽量选中Android内核可选选项

Device Drivers ---> Android ---> [*] RAM buffer console

Device Drivers ---> Android ---> [*] Android timed gpio driver

Device Drivers ---> Android ---> [*] Only allow certain groups to create sockets

(7) 其余CONFIG选项，如系统支持请一并选择

CONFIG_ANDROID_POWER =y

CONFIG_ANDROID_POWER_STAT =y

CONFIG_ANDROID_POWER_ALARM =y

（可以在Kconfig文件中查找ANDROID_POWER等字段进行选择，或者直接修改.config文件）

13、退出并保存.config

二、移植LCD驱动到Linux-2.6.25内核

1、 进入kernel.git文件夹，如cd ~/kernel.git/

2、 修改arch/arm/mach-s3c2410/mach-smdk2410.c文件，如gedit arch/arm/mach-s3c2410/mach-smdk2410.c

(1) 增加头文件#include

(2) 增加两给结构体

static struct s3c2410fb_display
