基于S3C2410平臺移植Linux 2.6內核指南

安裝交叉編譯工具
Ø 下載交叉編譯工具
（本文默認所有軟件均下載在用戶主目錄下）
arm-linux-gcc-3.4.1 —— 編譯內核
URL: ftp://ftp.handhelds.org/projects/toolchain/arm-linux-gcc-3.4.1.tar.bz2
Ø 安裝
//將壓縮包移動至根目錄下
#mv arm-linux-gcc-3.4.1.tar.bz2 /
//解壓，默認路徑為 /usr/local/arm /3.4.1
#tar jxvf arm-linux-gcc-3.4.1.tar.gz2
下載Linux內核
Ø 下載Linux 2.6.14.1內核
URL: http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.14.1.tar.bz2
Ø 解壓內核
#cd ~
#tar jxvf linux-2.6.14.1.tar.bz2
建立環(huán)境變量
Ø 將交叉編譯工具路徑和內核路徑加入環(huán)境變量
#vi ~/.bashrc
export KERNEL=~/linux-2.6.14.1
export PATH=/usr/local/arm/3.4.1/bin:$PATH
內核移植
Ø 為Flash進行分區(qū)
啟動開發(fā)板，進入vivi，對vivi進行分區(qū)操作
vivi>bon part 0 128k 192k 2240k 5312k:m 64704k
分區(qū)信息如下所示：
分區(qū) 起始地址 分區(qū)大小 分區(qū)作用
Part0 0x0 0x00020000 (128k) bootloader
Part1 0x00020000 0x00010000 (64k) bootloader params
Part2 0x00030000 0x00200000 (2m) linux kernel
Part3 0x00230000 0x00300000 (3m) root filesystem
Part4 0x00530000 0x03A00000 (58m) yaffs filesystem

將vivi寫進Flash
vivi>load flash vivi x
Ø 修改Makefile
#vi $KERNEL/Makefile
找到ARCH與CROSS_COMPILE，修改為
ARCH ?= arm
CROSS_COMPILE ?= arm-linux-
Ø 將分區(qū)信息加入內核
#vi $KERNEL/arch/arm/mach-s3c2410/devs.c
添加頭文件：
#include
#include
#include
添加分區(qū)結構：
static struct mtd_partition partition_info[]={
{
name: "loader", //分區(qū)名字，任意
size: 0x00020000, //分區(qū)大小
offset: 0x0, //分區(qū)的起始地址，相對于0x0的偏移
},{
name: "param",
size: 0x00010000,
offset: 0x00020000,
},{
name: "kernel",
size: 0x00200000,
offset: 0x00030000,
},{
name: "rootfs",
size: 0x00300000,
offset: 0x00230000,
},{
name: "yaffs",
size: 0x03A00000,
offset: 0x00530000,
}
};

struct s3c2410_nand_set nandset={
nr_partitions: 5, //分區(qū)數(shù)量
partitions: partition_info, //分區(qū)表
};
struct s3c2410_platform_nand superlpplatform={
//NAND Flash芯片支持
//參數(shù)意義可參考S3C2410手冊
tacls: 0,
twrph0: 30,
twrph1: 0,
sets: &nandset,
nr_sets: 1,
};
修改s3c_device_nand，以加入NAND Flash驅動：
struct platform_device s3c_device_nand = {
.name = "s3c2410-nand", //設備名稱
.id = -1, //有效設備編號，-1表示唯一設備
.num_resources = ARRAY_SIZE(s3c_nand_resource), //寄存器區(qū)的個數(shù)
.resource = s3c_nand_resource, //寄存器區(qū)的首地址
//添加如下信息，表示NAND Flash設備
.dev={
.platform_data=&superlpplatform
}
};
Ø 指定啟動時的設備初始化
#vi $KERNEL/arch/arm/mach-s3c2410/mach-smdk2410.c
修改：
static struct platform_device *smdk2410_devices[] __initdata = {
s3c_device_usb,
s3c_device_lcd,
s3c_device_wdt,
s3c_device_i2c,
s3c_device_iis,
//添加如下信息
s3c_device_nand,
};
Ø 禁止Flash ECC效驗
內核通過vivi把數(shù)據(jù)寫入NAND Flash，而vivi的ECC效驗算法和內核的不同，內核的效驗碼是由NAND Flash控制器產(chǎn)生的，所以在此必須禁用NAND Flash ECC。
#vi $KERNEL/drivers/mtd/nand/s3c2410.c
找到s3c2410_nand_init_chip函數(shù)，將chip->eccmode的值修改為：
NAND_ECC_NONE
Yaffs2加載
Ø 下載Yaffs2
URL: http://www.aleph1.co.uk/cgi-bin/viewcvs.cgi/yaffs2.tar.gz?view=tar
Ø 解壓Yaffs2并將其加入Linux內核
#cd ~
#tar zxvf yaffs2.tar.gz
#cd yaffs2
#sh patch-ker.sh c $KERNEL
內核配置（.config）與編譯
Ø 內核配置（基于$KERNEL/arch/arm/configs/s3c2410_defconfig）
（見附錄）
Ø 編譯內核
#make zImage
修改根文件系統(tǒng)
在宿主機上進入目錄/arm2410s（博創(chuàng)2410-s平臺提供），該目錄下的root目錄就是一個制作好的根文件系統(tǒng)。在此基礎上，我們要對root/etc/fstab分區(qū)配置文件進行修改，用來掛載Yaffs文件系統(tǒng)。
#vi /arm2410s/root/etc/fstab
找到y(tǒng)affs，修改為：
/dev/mtdblock/4 /mnt/yaffs yaffs defaults 1 1
然后制作根文件系統(tǒng)鏡像。
#mkcramfs root root.cramfs
安裝內核和根文件系統(tǒng)
Ø 將編譯好的內核2.6.14.1寫入Flash
vivi>load kernel x
Ø 將制作的根文件系統(tǒng)root.cramfs寫入Flash
vivi>load root x
Ø 修改vivi啟動參數(shù)
vivi>param set linux_cmd_line “noinitrd root=/dev/mtdblock3 init=/linuxrc console=ttySAC0,115200”
vivi>param save
Ø 重啟開發(fā)板，完成工作。
