简介
开发板首先移植好以太网驱动
主机端
安装 TFTP
root@ubuntu:/opt/android_linux-4.4# apt-get install tftp-hpa tftpd-hpa
root@ubuntu:/opt/android_linux-4.4# mkdir /opt/tftpboot/
root@ubuntu:/opt/android_linux-4.4# chmod 777 /opt/tftpboot/ 配置 TFTP
root@ubuntu:/opt/android_linux-4.4# vim /etc/default/tftpd-hpa
# /etc/default/tftpd-hpa
TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/opt/tftpboot"
TFTP_ADDRESS=":69"
TFTP_OPTIONS="-l -c -s"重启 tftp
root@ubuntu:/opt/android_linux-4.4# service tftpd-hpa restart安装NFS
apt-get install nfs-kernel-server配置NFS
root@ubuntu:/opt/fs/rootfs# vim /etc/exports
# /etc/exports: the access control list for filesystems which may be exported
# to NFS clients. See exports(5).
#
# Example for NFSv2 and NFSv3:
# /srv/homes hostname1(rw,sync,no_subtree_check) hostname2(ro,sync,no_subtree_check)
#
# Example for NFSv4:
# /srv/nfs4 gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check)
# /srv/nfs4/homes gss/krb5i(rw,sync,no_subtree_check)
#
/opt/fs/rootfs/rootfs *(rw,sync,no_root_squash)重启
NFS服务root@ubuntu:/opt/fs/rootfs# /etc/init.d/nfs-kernel-server restart [ ok ] Starting nfs-kernel-server (via systemctl): nfs-kernel-server.service.测试
root@ubuntu:/opt/fs/rootfs/rootfs# showmount -e Export list for ubuntu: /opt/fs/rootfs/rootfs *

<*> NFS client support开发板
[root@TINY4412:/]# mount -o nolock 192.168.2.40:/opt/fs/rootfs/rootfs /mnt
[root@TINY4412:/]# cd mnt/rootfs/
[root@TINY4412:/mnt/rootfs]# ls
bin etc mnt root sys
dev linuxrc proc sbin tmp这样便进入主机端挂载的根目录，这是在开发板端挂载，我们希望能不进入开发板的目录，直接将主机端的目录作为开发板的目录，实现无盘工作站的效果。
U-BOOT
TINY4412 # setenv bootargs noinitrd root=/dev/nfs rw nfsroot=192.168.2.40:/opt/fs/rootfs/rootfs/ ethmac=1C:6F:65:34:51:7E ip=192.168.2.39:192.168.2.40:192.168.2.1:255.255.255.0:TINY4412:eth0:off console=ttySAC0,115200 init=/linuxrc
TINY4412 # setenv bootcmd usb start\;tftp 0x41000000 uImage\;tftp 0x42000000 ramdisk.img\;tftp 0x43000000 exynos4412-tiny4412.dtb\;bootm 0x41000000 0x42000000 0x43000000
TINY4412 # setenv ipaddr 192.168.2.39
TINY4412 # setenv serverip 192.168.2.40noinitrd：必须配置，否则还是进入内存文件系统。
