移植Android内核到FS2410开发板上的方法与步骤 Android, 开发

苹果也疯狂

作者：王安





一、目前进展

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、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=$PWDPATH，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 Android''S 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
