完成时间：2017/6/2 16:08
版本：V1.0
开发板：MarsBoard全志A20
SDK：MarsBoard-A20-Linux-SDK-V1.2.tar.gz
1、解压缩全志A20的ubuntu的SDK：
rootroot@rootroot-E400:~$ cd wyb/
rootroot@rootroot-E400:~/wyb$ tar zxvf MarsBoard-A20-Linux-SDK-V1.2.tar.gz
（默认配置为HDMI输出了，要通过LCD输出需要修改sys_config.fex文件）
rootroot@rootroot-E400:~/wyb/MarsBoard-A20-Linux-SDK-V1.2$ find . -name sys_config.fex

2、遵照readme.txt的步骤编译系统
（本文为直接成刷NAND的IMG系统，不喜欢用TF卡，个人总感觉不可靠）

3、生成的IMG大概有2GB，刷机大概需要10分钟+时间。
（总之，好慢好慢地呀！）

使用iwconfig命令：
搜索无线网 iwlist wlan0 scan
记下essid
连接无密码的无线网 iwconfig wlan0 essid ChinaNet 其中ChinaNet是搜索到的无线网essid
连接有密码的无线网 iwconfig wlan0 essid ChinaNet key xxxx 其中xxxx是密码
启用无线网卡 ifconfig wlan0 up
通过dhcp获取IP dhclient wlan0 或 dhcpcd wlan0

iwconfig 无线设置问题
我按照网上的做法想无线上网，但执行：
[root@www ~]# iwconfig wlan0 essid "zmd" key 12345678
Error for wireless request "Set Encode" (8B2A) :
SET Failed on device wlan0 ; Invalid argument.
用户和密码都没错，这是什么原因呢？
当我改掉密码时反而行了，但明明这个密码是错的啊！
root@www ~]# iwconfig wlan0 essid "zmd" key 012345678
[root@www ~]# iwconfig wlan0
wlan0 IEEE 802.11bgn ESSID:"zmd"
Mode:Managed Access Point: Not-Associated Tx-Power=13 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Encryption key:0012-3456-78 #这里也不明白为啥变成这样？
Power Management:on
望解答，谢谢！
系统是10.04，问题出在ubuntu对wpa加密方式不支持。
将AP配置成无密码连接，那么用iwconfig wlan0 essid xxx连接成功
AP密码全部为数字的话，不会报错，但仍连不上
AP密码是字母加数字的话，就会报楼主的错误
解决方法是用wpasupplicant软件：
#wpa_passphrase ESSID PWD > xxx.conf
#wpa_supplicant -B -i wlan0 -Dwext -c ./xxx.conf
#iwconfig wlan0
#dhclient wlan0
之后就成功啦
参考http://www.2cto.com/net/201210/160113.htm
（WIFI：rtl8188eu连网失败，原因不明。可以发现AP，但是连接不上，也许驱动有问题）
