如何將Android移植到FS2410開發(fā)板上

一、目前進(jìn)展
1．Android已經(jīng)可以通過NFS在FS2410開發(fā)板上運行

二、目前缺陷
1．觸摸屏沒有校準(zhǔn)
2．Android中時鐘停止，結(jié)束zygote進(jìn)程，系統(tǒng)重啟，時鐘更新，但再次停止不動
3．串口無法與GPRS模塊通訊

三、移植步驟
一、移植Android內(nèi)核到FS2410開發(fā)板上
1、下載linux-2.6.25-android-1.0_r1.tar.gz

2、將內(nèi)核解壓到用戶目錄，如/home/wangan/kernel.git

3、進(jìn)入kernel.git文件夾，如cd ~/kernel.git/

4、修改arch/arm/plat-s3c24xx/common-smdk.c文件中的nand flash分區(qū)設(shè)置，如gedit arch/arm/plat-s3c24xx/common-smdk.c
修改static struct mtd_partition smdk_default_nand_part[]結(jié)構(gòu)體為：
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、在網(wǎng)站上下載IA32 GNU/Linux TAR。

6、將文件解壓到用戶目錄，如/home/wangan/arm-2008q3

7、進(jìn)入arm-2008q3/bin文件夾，如cd ~/arm-2008q3/bin/

8、添加當(dāng)前路徑進(jìn)入環(huán)境變量，如export PATH=$PWD:$PATH，或修改~/.bashrc文件并重新登錄

9、進(jìn)入內(nèi)核文件夾，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、從華清遠(yuǎn)見Linux-2.6.8.1內(nèi)核壓縮包中提取.config文件（注意：config前面有個“.”）放入kernel.git文件夾

12、運行make menuconfig
(1) 確保System Type ---> ARM system type ()中的內(nèi)容為Samsung S3C2410, S3C2412, S3C2413, S3C2440, S3C2442, S3C2443
(2) 確保System Type ---> S3C2410 Machines ---> [*] SMDK2410/A9M2410被勾選
(3) 取消選擇與Goldfish相關(guān)的內(nèi)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) 選擇S3C2410 LCD相關(guān)的內(nèi)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) 選中Android內(nèi)核必須選項
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) 盡量選中Android內(nèi)核可選選項
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選項，如系統(tǒng)支持請一并選擇
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等字段進(jìn)行選擇，或者直接修改.config文件）

13、退出并保存.config
