将Android移植到FS2410开发板上

一、现在发展

1．Android现已能够经过NFS在FS2410开发板上运转

二、现在缺点

1．触摸屏没有校准

2．Android中时钟中止，完毕zygote进程，体系重启，时钟更新，但再次中止不动

3．串口无法与GPRS模块通讯

三、移植过程

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、修正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

修正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、添加当时途径进入环境变量，如export PATH=$PWD:$PATH，或修正~/.bashrc文件并从头登录

9、进入内核文件夹，如cd ~/kernel.git/

10、修正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（留意：config前面有个“.”）放入kernel.git文件夹

12、运转make menuconfig

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

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

(3) 撤销挑选与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) 挑选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内核有必要选项

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) 其他CONFIG选项，如体系支撑请同时挑选

CONFIG_ANDROID_POWER =y

CONFIG_ANDROID_POWER_STAT =y

CONFIG_ANDROID_POWER_ALARM =y

（能够在Kconfig文件中查找ANDROID_POWER等字段进行挑选，或许直接修正.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、 修正arch/arm/mach-s3c2410/mach-smdk2410.c文件，如gedit arch/arm/mach-s3c2410/mach-smdk2410.c

(1) 添加头文件#include

(2) 添加两给结构体

static struct s3c2410fb_display smdk2410_lcd_cfg __initdata = {

.lcdcon5 = S3C2410_LCDCON5_FRM565 |

S3C2410_LCDCON5_INVVLINE |

S3C2410_LCDCON5_INVVFRAME |

S3C2410_LCDCON5_PWREN |

S3C2410_LCDCON5_HWSWP,

.type = S3C2410_LCDCON1_TFT,

.width = 320,

.height = 240,

.pixclock = 174757,

.xres = 320,

.yres = 240,

.bpp = 16,

.left_margin = 16,

.right_margin = 59,

.hsync_len = 9,

.upper_margin = 2,

.lower_margin = 6,

.vsync_len = 16,

};

static struct s3c2410fb_mach_info smdk2410_fb_info __initdata = {

.displays = &smdk2410_lcd_cfg,

.num_displays = 1,

.default_display = 0,

.gpccon = 0xaa955699,

.gpccon_mask = 0xffc003cc,

.gpcup = 0x0000ffff,

.gpcup_mask = 0xffffffff,

.gpdcon = 0xaa95aaa1,

.gpdcon_mask = 0xffc0fff0,

.gpdup = 0x0000faff,

.gpdup_mask = 0xffffffff,

.lpcsel = 0xf82,

};

(3) 在smdk2410_init（）函数中添加s3c24xx_fb_set_platdata(&smdk2410_fb_info);

三、移植触摸屏驱动到Linux-2.6.25内核（拜见《根据linux-2.26.5内核的FS2410开发板触摸屏驱动移植》）并制造zImage文件，如make

这儿提一下，保证现已勾选Device Drivers —> Input device support —> <*> Event interface，自己从前在这儿徜徉，感谢游教师尽心教导！

四、制造支撑ARMv4的Android根文件体系

1、从http://www.rayfile.com/files/d4660882-de04-11dd-af0d-0014221b798a/下载Android的ARMv4版别根文件

2、在/dev下添加null和console两个设备节点

mknod -m 660 null c 1 3

mknod -m 660 console c 5 1

3、在U-boot中修正发动参数init为/init，完好的指令行如：root=nfs nfsroot=169.254.7.118:/source/rootfs ip=169.254.7.119 console=ttySAC0,115200 init=/init

4、修正/init.rc文件，去除除mount tmpfs tmpfs /sqlite_stmt_journals size=4m之外的一切mount指令

体系制造完结，现在应该能够看到美丽的大表了。初次发动需求创立文件，大约17分钟。然后每次发动只需求2分钟。
