2、设置U-boot网络环境

在U-boot命令提示行下使能usb和usb网卡：

$ usb start //使能usb。

$ usb reset //搜索usb网卡设备。

结果如下图所示：





从上图我们可看到网卡的MAC地址为00:00:ff:ff:00:00

3>、设置网卡地址：

$ setenv usbethaddr 00:00:ff:ff:00:00

$ saveenv

4>、设置开发板IP地址（与宿主机Ubuntu在同一个IP网段）：

$ setenv ipaddr 192.168.1.103

$ saveenv

5>、设置宿主机tftp服务器IP地址：

$ setenv serverip 192.168.1.102

$ saveenv

6> 查看U-boot环境变量：

$ printenv

3、使用TFTP服务

宿主机tftp服务器配置参考《Ubuntu14.04环境下配置TFTP服务器》。

使用TFTP服务前，先重启下宿主机的TFTP服务：

$ sudo service tftpd-hpa restart //重启服务器

$ sudo /etc/init.d/xinetd reload

$ sudo /etc/init.d/xinetd restart //重启xinetd，tftp的一个脚本

把uImage、ramdisk.img和exynos4412-tiny4412.dtb拷贝到tftp服务器目录下，在U-boot命令提示行执行如下命令下载uImage、ramdisk.img和exynos4412-tiny4412.dtb:

# tftp 0x40600000 uImage

# tftp 0x41000000 ramdisk.img

# tftp 0x42000000 exynos4412-tiny4412.dtb

# bootm 0x40600000 0x41000000 0x42000000

启动信息如下：





4、设置开发板上电从TFTP启动

完成U-boot网络环境设置后，通过设置bootcmd变量使开发板上电从tftp启动：

# setenv bootcmd 'usb start; usb reset;tftp 0x40007000 uImage; tftp 0x48000000 ramdisk.img; tftp 0x42000000 exynos4412-tiny4412.dtb; bootm 0x40007000 0x48000000 0x42000000; boot'

# saveenv

设置完成后重启开发板。
