之前由于某些事情比较忙，有一段比较长的时间没有更新了，被可依数次提醒了

这次就来更新了~
由于板子上面没有带有串口转USB芯片，因此需要外接一个Uart转USB的模块，我使用的是FT232的芯片，总共三根线：Tx、Rx、GND，模块上Rx接板子上Tx；模块上Tx接板子上Rx；
在软件上我使用SecureCRT软件，这个软件支持多个功能，我用它来与开发板沟通。

插上外置电源，上电，设置好串口波特率和端口后串口打印出以下内容：

Freescale i.MX Release Distro 4.1.15-2.0.1 myd-y6ul14x14 /dev/ttymxc0

复制代码

看起来启动成功，采用的是uboot+Freescale定制系统，基于Debian修改的，内存为256Mb，Nand Flash也为256Mb。登录名为root，没有设置密码~
既然上手自然要看一下原装系统的参数：
输入以下参数查看Linux内核版本

cat /proc/version

复制代码

输入以下参数查看CPU参数

cat /proc/cpuinfo

复制代码

ARMv7处理器，A7架构有点老，但是架构成熟，性价比高。

输入以下参数查看分区情况

df -h

复制代码

就只有一个256Mb分区，用了近30%，最下面那个mmcblk0p1是我插进去的16G MicroSD卡。

输入以下参数查看内存情况

cat /proc/meminfo

复制代码

作为一个有WIFI的板子，查看完参数之后就一定要连接WIFI，在配置WIFI过程中，需要使用Uart接口进行配置。别忘了在配置WIFI前装好随板子附带的WIFI天线。
在命令行中输入以下生成对应的PSK

cd ~

复制代码

其中myWIFI替换成你要连接WIFI网络的名字，myPassWord替换成WIFI网络密码。

然后输入以下命令查看有没有生成对应的PSK：

cat wifi.conf

复制代码

此时屏幕会打印出wifi.conf文件内容，看一下WIFI名字和密码对不对，PSK有没有生成就好了。此时这个wifi.conf配置文件已经保存在~中，即是用户文件夹中，下一次连接wifi就不需要再次生成了，直接导入进去。

然后接着输入以下命令导入进去，连接WIFI网络

wpa_supplicant -D wext -B -i wlan0 -c wifi.conf

复制代码

在连接了WIFI还不能上网，还需要向路由器DHCP取分配的IP地址和其他网络参数。

输入以下命令进行获取DHCP信息

udhcpc -b -i wlan0 -R

复制代码

到此步应该就成功了

输入以下命令查看是否获取成功：

ifconfig wlan0

复制代码

既然连上网了，先来测试一下是否能够ping通外网地址：
输入以下命令来测试一下是否能正确获取和链接爱板网的ip地址吧~

ping -c 5 www.eeboard.com

复制代码

如果没问题的话应该如图所示，爱板网网速还是挺快的~

既然能ping通，接下来就试试telnet功能吧，由于telnet没有加密，因此安全性并不是很好，现在基本淘汰了，但是telnet还有一个很好玩的地方，可以用来看“电影”，整个“电影”由字符串组成，主题是星战，不得不佩服国外作者的耐心~
输入以下命令即可观看：

telnet towel.blinkenlights.nl

复制代码

这个一直看就行，不用操作，退出按Ctrl+C即可

联网已经搞定了，能够联网对于我们来说就很方便了，可以通过WIFI来操作，我们可以通过一个加密的telnet来连接开发板来操作，这样就不需要Uart转USB的模块了，开发也方便多了。我所采用的是SSH2协议，SSH2是经过SSL加密处理的，更加安全，SecureCRT软件也支持该种方式进行登录。
在开始配置之前，需要查看路由器分配给开发板的IP地址，输入：

ifconfig wlan0

复制代码

查看ip地址一栏，并且记下来。然后设置SecureCRT来连接，hostname为之前查看的开发板ip地址，端口为22。

对于Linux用户来说，Linux也支持SSH登录方式，没有安装的可以去下载安装OpenSSH。
这里以Ubuntu为例，Ubuntu本身预装了，只需输入以下命令：

ssh root@192.168.1.2

复制代码

注意，192.168.1.2替换为你之前查到的开发板ip地址。

对于想通过WIFI来传输文件的用户，SecureCRT支持SFTP功能，来进行文件安全加密的互传。但是启动失败了，经查是米尔的板子安装了OPENSSH，但是并没有安装SFTP功能，缺少文件，所以没有进行。
不过，对于一般用户来说，特别是在内网中使用的话，使用简易没加密版的TFTP也可以的。米尔预装的系统中有TFTP功能，可以提供简单的文件互传功能。

对于Linux用户，需要安装tftp-server功能，这里就不说了~
对于Windows用户，系统已经自带了TFTP功能，但是很可能没有安装，需要到控制面板中安装一下。如果不想安装，可以推荐使用一个绿色版小型TFTP软件——tftpd64（32位为tftpd32），自带Client和Server模式，最重要的是占空间小。绿色包我放在论坛上，直接运行不用安装！

tftpd64.460.zip (517.06 KB, 下载次数: 1, 售价: 1 与非币)

Tftpd64界面如下，很简洁

在传输之前需要设置一下，Server interfaces中选中网卡，在此我使用的是有线网卡，因此选中它。

点击Setting，然后在TFTP选项卡中Base Directory中选择接受和发送的文件夹地址。

在DHCP选项卡中，填入下图红框中的内容，以下数值因不同设备而不同，请根据路由器参数而设置。

已经设置完成了，接下来往开发板中写入命令，在此以wifi.conf为例，往TFTP服务器（电脑）中传输这个文件。
TFTP命令很简单：

tftp (参数1) xxx.xx (参数2) (IP地址)

复制代码

参数1有 -l 本地文件； -r 服务器文件
参数2有 -g 取文件； -p 发送文件
ip地址为电脑ip地址
常用的只有两个，就是下面例子所说的：

输入以下命令

cd ~
tftp -l wifi.conf -p 192.168.1.4

复制代码

其中192.168.1.4为电脑的ip地址，可以在软件中Servers interfaces中看到。
可以看到正在传输中

可以在Log日志文件中看到已经把这个文件传输到电脑中了。

接下来要测试一下开发板中从电脑中提取一个文件。我们在电脑随便建立一个待提取的文件，这里以test.txt为测试文件，并把这个文件放在刚刚设置好的Base Directory目录中。

往开发板中输入以下命令提取文件：

tftp -r test.txt -g 192.168.1.4

复制代码

在日志中可以看出开发板已经成功提取了文件

在命令行中可以看到多了test.txt文件，用cat输出文件正是服务器中测试的文件，说明传输成功了。
