x210项目重新回顾之七uboot_2013.10之nfs方式启动内核
开发板IP：131.128.52.97
虚拟机服务端ip：131.128.52.51
1）uboot设置bootargs 为nfs启动
setenv bootargs "root=/dev/nfs rw nfsroot=131.128.52.51:/tftpboot/nfs,proto=tcp,nfsvers=3,nolock ip=131.128.52.97:131.128.52.51:131.128.52.1:255.255.255.0::eth0:off console=ttySAC2,115200 init=/linuxrc"
2）Linux内编译
A）make ARCH=arm x210ii_initrd_defconfig (初步配置，生成 .config)
B) 通过menuconfig二次修改，开启nfs配置（见我之前文章s5pv210的学习之路（21）x210的kernel的NFS的根文件系统编译，使用_weixin_43097675的博客-CSDN博客）
C)>修改 .config
这里nfs文件系统为九鼎提供的 rootfs_qt4.ext3 ，我把它mount 然后拷贝到/tftpboot/nfs/
CONFIG_CMDLINE=”noinitrd mem=512M console=ttySAC2,115200 root=/dev/nfs nfsroot=131.128.52.51:/tftpboot/nfs ip=131.128.52.97:131.128.52.51:131.128.52.51:255.255.255.0::eth0:off”
D)
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- -j 4
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- zImage
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- uImage
>cp arch/arm/boot/ zImage /tftpboot/zImage-nfs
3）虚拟机服务端开启nfs服务
$ sudo apt install nfs-kernel-server
$ sudo chown nobody:nogroup /tftpboot/nfs
$ sudo chmod 777 /tftpboot/nfs
$ sudo nano /etc/exports （注意一定要可读写权限，否者内核启动会报权限问题）
/tftpboot/nfs *(rw,sync,no_root_squash,subtree_check)
3）uboot下载内核，启动
>tftp 30008000 zImage-nfs (zImage-nfs在虚拟机/tftpboot/里面)
>bootm 30008000
启动后输出：

tftp问题解决：
如果出现找不到文件，不能下载，可以尝试重新安装tftp：
sudo apt-get install xinetd tftpd tftp2）并且添加tftp用户：
sudo chmod -R 777 /tftpboot
sudo chown -R nobody /tftpboot
sudo service xinetd restart
