按照飞凌嵌入式Linux手册内容编译u-boot2009-08、内核和文件系统，通过下载工具装载3个
镜像至EMMC中，通过上电启动，u-boot正常运行，引导装载运行内核和文件系统。
u-boot的默认环境变量为：
MX6Q SABRESD U-Boot > printenv
bootdelay=3
baudrate=115200
ipaddr=192.168.1.103
serverip=192.168.1.101
netmask=255.255.255.0

codec_name=audio_codec=wm8960-24M

ethprime=FEC0
splashimage=0x30000000

bootargs_nfs=setenv bootargs ${bootargs} root=/dev/nfs ip=dhcp nfsroot=${serverip}:${nfsroot},v3,tcp
bootcmd_net=run bootargs_base bootargs_nfs; tftpboot ${loadaddr} ${kernel}; bootm

bootcmd_mmc=run bootargs_base bootargs_mmc; mmc dev 3; mmc read ${loadaddr} 0x800 0x2900; bootm
bootcmd=run bootcmd_mmc
wdtenable=disable
stdin=serial
stdout=serial
stderr=serial
ethact=FEC0
Environment size: 1023/8188 bytes
执行：
1、setenv ethaddr 00:E0:C0:66:88:99
2、setenv nfsroot /nfs_rootfs
3、setenv bootcmd run bootcmd_net
按照以上命令配置好u-boot环境变量，更新ubuntu12.04宿主机IP为192.168.1.101,window10主机IP为192.168.1.102，
u-boot自身IP地址为192.168.1.103不变。各模块之间通过交换机链接。
重新上电启动后，能下载内核，但不能加载/nfs_rootfs文件夹下的文件系统，输出打印信息如下：
