20100608_u-boot参数配置

nand flash uboot参数.最原始参数.可启动nfs文件系统 tftp有问题...
bootdelay=1
baudrate=115200
ethaddr=08:08:11:18:12:27
tekkaman=bmp d 70000
 stdin=serial
stdout=serial
stderr=serial
mtdids=nand0=nandflash0
bootargs=noinitrd root=/dev/nfs rw nfsroot=192.168.1.111:/work/nfs ip=192.168.1.8:192.168.1.111:192.168.1.1:255.255.255.0 console=ttySAC0,115200 init=/linuxrc mem=64M
bootcmd=nfs 0x30000000 192.168.1.111:/work/nfs/uImage;bootm
filesize=1BD699
fileaddr=30000000
netmask=255.255.255.0
ipaddr=192.168.1.8
autostart=no
serverip=192.168.1.199

nor flash 参数,配置好.nfs,tftp均可正常使用,使用国嵌移植后源代码编译,烧定到nor上面
Mini2440 # printenv
bootdelay=3
baudrate=115200
netmask=255.255.255.0
serverip=192.168.1.111
ethaddr=08:08:11:18:12:27
ipaddr=192.168.1.156
bootargs=noinitrd root=/dev/nfs rw nfsroot=192.168.1.111:/work/nfs ip=192.168.1.8:192.168.1.111:192.168.1.1:255.255.255.0 console=ttySAC0,115200 init=/linuxrc mem=64M
bootcmd=nfs 0x31000000 192.168.1.111:/work/nfs/uImage;bootm
stdin=serial
stdout=serial
stderr=seria

手册上参数设置
PS:网卡配置
vim /etc/sysconfig/network-scripts/ifcfg-eth0
目前新的网络环境
DHCP 192.168.10.XXX
GATEWAY:192.168.10.1
所以进行如下改动
serverip 192.168.10.111
ipaddr 192.168.10.125
netmask 255.255.255.0

以下是配置步骤
setenv serverip 192.168.10.111
setenv ipaddr 192.168.10.125
saveenv
OK
如果配置好tftp可以下载测试一下
Mini2440 # tftp 31000000 uImage-uboot
