1.下载arm-linux-gcc-4.3.2.tar.gz交叉编译环境，并安装。
2.移植u-boot-1.1.6，参照网上的帖子，添加u-boot的nand read和write功能。
3.编译linux-2.6.24.4内核
arch ?= arm
cross_complie ?= /usr/local/arm/4.3.2/bin/arm-linux-
kbuild_flags 添加 “-fno-tree-scev-cprop”,解决__udivdi3的reference找不到的问题
内核需要支持EABI
make zImage 之后需要通过mkImage命令将zImage转换成uboot可以引导的uImage.命令如下：
mkImage -n "linux-2.6.24.4-safeman-arm" -A arm -O linux -T kernel -C none -a 0x30007fc0 -e 30008000 -d zImage uImage
这里解释一下参数的意义：
-A == set architecture to 'arch'
-O == set operating system to 'os'
-T == set image type to 'type'
-C == set compression type 'comp'
-a == set load address to 'addr' (hex)
-e == set entry point to 'ep' (hex)
-n == set image name to 'name'
-d == use image data from 'datafile'
-x == set XIP (execute in place)
4.设置uboot的tftp参数
setenv serverip 192.168.0.235
setenv ethaddr 00:12:13:14:15:16
setenv ipaddr 192.168.0.75
setenv netmask 255.255.255.0
saveenv
5.烧录uImage到nand flash
nand erase 0x100000 0x200000;tftp 0x30008000 uImage;nand write 0x30008000 0x100000 0x18274c
nand erase 起始地址 大小
tftp 下载地址 下载文件名
nand write 文件存储地址 文件要写入的起始地址 文件大小
6.制作根文件系统jffs2类型
编译busybox-1.16.1
选择动态编译
arch ?= arm
cross_complie ?= /usr/local/arm/4.3.2/bin/arm-linux-
制作rootfs目录项，将相应的文件copy过来。
通过arm-linux-readelf -d filename查看文件需要的动态链接库，对应s3c2410平台来说，需要 armv4t/lib/下的链接库
制作jffs2的image
/extend/src/mtd-utils-v1.4.6-baafd8a/mkfs.jffs2 -r rootfs -o jffs2.img -e 0x4000 --pad=0x400000 -n
# --pad size must be equal the size of mtdblock.
#such as: root=/dev/mtdblock7, /dev/mtdblock7 size is 0x1000000,
# then generate command should is
# mkfs.jffs2 -r rootfs -o jffs2.img -e 0x4000 --pad=0x1000000 -n
#-e means the erase block size. Deferent nand flashes have deferent erase block size.
7.烧录jffs2.img到mtdblock2分区
nand flash的分区情况：
0x00000000-0x00004000 : "Boot Agent"
0x00000000-0x00200000 : "S3C2410 flash partition 1"
0x00400000-0x00800000 : "S3C2410 flash partition 2"
0x00800000-0x00a00000 : "S3C2410 flash partition 3"
0x00a00000-0x00e00000 : "S3C2410 flash partition 4"
0x00e00000-0x01800000 : "S3C2410 flash partition 5"
0x01800000-0x03000000 : "S3C2410 flash partition 6"
0x03000000-0x04000000 : "S3C2410 flash partition 7"
tftp 0x30008000 jffs2.img;nand erase 0x400000 0x400000;nand write 0x30008000 0x400000 0x400000
8.设置启动参数
set bootcmd nand read 0x30007fc0 0x100000 0x18274c\;bootm 0x30007fc0;saveenv
setenv bootargs root=/dev/mtdblock2 rootfstype=jffs2 rw init=/linuxrc noinitrd console=ttySAC0,115200;saveenv
