UBOOT操作指令例子

1.首先确保你当前使用的uboot支持nand write功能

tftp 0x50800000 zImage

nand erase 0x100000 0x1C0000

nand write 0x50800000 0x100000 0x1C0000 // 将sdram 0x30800000位置处的数据写到nandflash的0x40000位移处,写入大小为0x1C0000

//烧写zImage: // ok

tftp 0x30800000 zImage

nand erase 0x40000 0x1C0000

nand write 0x30800000 0x40000 0x1C0000 // 将sdram 0x30800000位置处的数据写到nandflash的0x40000位移处,写入大小为0x1C0000

//烧写uImage: // ok

tftp 0x30800000 uImage

nand erase 0x40000 0x1C0000

nand write 0x30800000 0x40000 0x1C0000 // 将sdram 0x30800000位置处的数据写到nandflash的0x40000位移处,写入大小为0x1C0000

//烧写rootfs.cramfs: // ok

tftp 0x30800000 rootfs_fs2410.cramfs // 这里下载的数据大小,就是后面的0x xxx的值

nand erase 0x200000 0x2000000

nand write 0x30800000 0x200000 0x xxx // 将sdram 0x30800000位置处的数据写到nandflash的0x200000位移处,写入大小为0x1C0000

//烧写rootfs.jffs2: // ok

tftp 0x30800000 rootfs_fs2410.jffs2 // 记得先改cmdline参数

nand erase 0x200000 0x2000000

nand write.jffs2 0x30800000 0x200000 0x xxx // 将sdram 0x30800000位置处的数据写到nandflash的0x200000位移处,写入大小为0x1C0000

*************************************************************************************

用nfs烧录rootfs的时候需要先擦除nand flash，需要将rootfs文件压缩为命名为 .tgz 的后缀名称。否则用tar xvf 命令解压不了文件。会

提示以下信息：

tar: no gzip/bzip2 magic

打包根文件系统的时候需要注意，需要打包的是rootfs里面的文件，并不是连rootfs文件夹一起，否则无法加载。

本人的环境变量为：

SMDK6410 # printenv

bootcmd=nand read 0xc0008000 0x100000 0x400000;bootm 0xc0008000

bootdelay=3

baudrate=115200

ethaddr=00:40:5c:26:0a:5b

netmask=255.255.255.0

ipaddr=192.168.2.183

severip=192.168.2.204

gatewayip=192.168.2.1

serverip=192.168.2.204

bootargs=root=/dev/nfs nfsroot=192.168.2.204:/usr/nfs/rootfs/hptest/rootfs ip=192.168.2.183:192.168.2.204:192.168.2.1:255.255.255.0::eth0:off console=ttySAC0,115200

stdout=serial

stderr=serial

烧录好文件系统后需要修改bootargs的环境变量值。

setenv bootargs "root=/dev/mtdblock2 rootfstype=yaffs2 console=ttySAC0,115200"

saveenv

setenv bootargs "root=/dev/nfs nfsroot=192.168.2.204:/usr/nfs/rootfs/hptest/rootfs ip=192.168.2.183:192.168.2.204:192.168.2.1:255.255.255.0::eth0:off console=ttySAC0,115200"

saveenv

setenv bootargs "root=/dev/nfs nfsroot=192.168.2.204:/usr/nfs/rootfs/hptest/myrootfs/rootfs ip=192.168.2.183:192.168.2.204:192.168.2.1:255.255.255.0::eth0:off console=ttySAC0,115200"

saveenv

setenv bootargs "root=/dev/nfs nfsroot=192.168.8.92:/home/maozt/imcpfs ip=192.168.8.236:192.168.8.92:192.168.8.1:255.255.255.0::eth0:off console=ttySAC0,115200"

自己设置nfs

setenv bootargs "root=/dev/nfs nfsroot=192.168.2.204:/usr/nfs/rootfs/hptest

ip=192.168.2.183:192.168.2.204:192.168.2.1:255.255.255.0::eth0:off console=ttySAC0,115200"

setenv bootargs "root=/dev/nfs nfsroot=192.168.2.204:/usr/nfs/rootfs/hptest/rootfs ip=192.168.2.183:192.168.2.204:192.168.2.1:255.255.255.0::eth0:off console=ttySAC0,115200"

将文件系统写到mtdblock2中的脚本

mount -t nfs -o intr,nolock,rsize=1024,wsize=1024 -o tcp 192.168.2.67:/usr/nfs /tmp/nfs
