「linux」s3c2416uboot相关配置nfs等

• Uboot命令下查看参数命令:

print

• 设置板子IP、LINUX虚拟机服务器IP、网关IP命令：

setenv ipaddr 192.168.3.128;setenv serverip 192.168.3.15;setenv gatewayip192.168.3.255

• NFS挂载：

PC:

apt-get install nfs-common

aptitude install nfs-kernel-server

在/etc/exports文件中加入一句/opt/root_qtopia *(rw,sync,no_subtree_check)//no_root_squash

exportfs -r

/etc/init.d/portmap restart

/etc/init.d/nfs-kernel-server restart

ufw disable

shutdown -r now

mount -t nfs 192.168.0.15:/opt/nfsfile /mnt

2416板：

设置板子IP、LINUX虚拟机服务器IP、网关IP命令：

setenv ipaddr 192.168.3.128;setenv serverip 192.168.3.15;setenv gatewayip192.168.3.255

setenv bootargs noinitrd root=/dev/nfs rwnfsroot=192.168.3.15:/opt/root_qtopia/ip=192.168.3.128:192.168.3.15:255.255.255.0 console=ttySAC1,115200

• 直接板上启动命令：

set bootargs root=/dev/mtdblock2 console=ttySAC1,115200

• 参数设置完成保存命令：（每个参数设置后均要保存）

save
