简介一边听听音乐，一边写写文章。

内核分区空间：
Creating 4 MTD partitions on "NAND 64MiB 3,3V 8-bit":
0x00000000-0x00080000 : "Bootloader"
0x00080000-0x00280000 : "Linux Kernel"
0x00280000-0x00680000 : "Root File System"
0x00680000-0x04000000 : "User Space"
烧写u-boot：
tftp 0x30008000 u-boot.bin
nand erase 0x0 0x80000
nand write 0x30008000 0x0 0x80000
烧写内核：
tftp 0x30008000 uImage
nand erase 0x80000 0x200000
nand write 0x30008000 0x80000 0x200000
烧写文件系统：
tftp 0x30008000 root.cramfs
nand erase 0x280000 0x400000
nand write 0x30008000 0x280000 0x400000
[smdk2410#]setenv bootcmd nand read 0x30008000 0x80000 0x200000\;bootm
[smdk2410#]saveenv
[smdk2410#]setenv bootargs root=/dev/mtdblock2 init=/linuxrc console=ttySAC0,115200
[smdk2410#]saveenv
Saving Environment to NAND...
Erasing Nand...Writing to Nand... done
[smdk2410#]printenv
bootargs=root=/dev/mtdblock3 init=/linuxrc console=ttySAC0,115200
bootcmd=tftp; bootm
bootdelay=3
baudrate=115200
ethaddr=08:00:3e:26:0a:5b
ipaddr=192.168.1.131
serverip=192.168.1.132
netmask=255.255.255.0
bootfile="uImage"
stdin=serial
stdout=serial
stderr=serial
修改ROOT分区
[smdk2410#]setenv bootargs root=/dev/mtdblock2 init=/linuxrc
console=ttySAC0,115200
[smdk2410#]saveenv
修改TFTP到NANDFLASH
[smdk2410#]setenv bootcmd nand read 0x30008000 0x80000 0x200000\; bootm
[smdk2410 #]printenv
bootargs=root=/dev/mtdblock2 init=/linuxrc console=ttySAC0,115200
bootdelay=3
baudrate=115200
ethaddr=08:00:3e:26:0a:5b
ipaddr=192.168.1.131
serverip=192.168.1.132
netmask=255.255.255.0
bootfile="uImage"
stdin=serial
stdout=serial
stderr=serial
bootcmd=nand read 0x30008000 0x80000 0x160000; bootm
Environment size: 298/16380 bytes
[smdk2410#]saveenv
Saving Environment to NAND...
Erasing Nand...Writing to Nand... done
[smdk2410#]reset
这样重启过后就会进入我们所移植的linux系统中，所有烧写工作完成。
