1.检查<br> 
<span style="background:#CCCCCC">check</span><br>
底板跟核心板的连接。如果核心板跟底板是单独分开，请按照附录中的核心板的插拔方法将核心板插在底板上 <br>
<span style="background:#CCCCCC">connection between base board and core board. if core board and base board is seperated,please insert core board in the base board in the way described in the appendix.</span><br>
2.准备<br> 
<span style="background:#CCCCCC">prepare</span><br>
准备好串口线（跟 PC 机直连的串口线，也可以用 USB 转串口线），以太网线，电源（直流 5V，2A 及以上）。 <br>
<span style="background:#CCCCCC">get ready serial port line(serial port line which can be connected directly with PC,or USB to serial port line),ethernet line,power supply(DC 5V,2A or above)</span><br>
3.配置串口<br> 
<span style="background:#CCCCCC">configure serial port</span><br>
选择合适的串口 <br>
<span style="background:#CCCCCC">choose proper serial port</span><br>
[[文件:MY_I.MX6_DEMO_Android4.2.2_1.png]]<br>
<br>
端口做如下设置 <br>
<span style="background:#CCCCCC">set interface as below</span><br>
<br>
[[文件:MY_I.MX6_DEMO_Android4.2.2_2.png]]<br>
3.操作 <br>
<span style="background:#CCCCCC">operation</span><br>
将核心板 2 位拨码开关拨到 1：OFF，2：ON 处 <br>
<span style="background:#CCCCCC">turn  2 bit dial switch to 1：OFF，2：ON </span><br>
将串口线连接到 MY-I.MX6X 底板上的串口上（图 1 中的图示 11） <br>
<span style="background:#CCCCCC">connect serial port line to serial port of base board of MY-I.MX6X (icon 11 in figure1)</span><br>
将开关（图 1 中的图示 12）拨到断开状态（—：闭合，O:断开） <br>
<span style="background:#CCCCCC">turn swtich(icon12 in figure1) to be off status(1:closed,0:off)</span><br>
将 5V 电源插到电源接口（图 1 中的图示 13）。<br> 
<span style="background:#CCCCCC">plug 5V power supply in the power interface</span><br>
闭合开关，串口将有信息输出 <br>
<span style="background:#CCCCCC">close the swtich, there will be output of information in the serial port</span><br>
系统默认是从 SPI 启动，加载 SD 或 EMMC 中的内核和文件系统，系统默认的液晶显示接口是 LVDS1 接口（图 1 中图示 3） <br>
<span style="background:#CCCCCC">defaulted booting by system start with SPI,load SD or kernel and file system in EMMC,defaulted display interface of crystal liquid by system is LVDS1(icon3 in figure1)</span><br>
开机之后，会有启动 logo，如果发现开机 logo 不能够显示正常，请关闭电源 3 秒，再开机等待系统起来之后 进入 android 界面。进入界面之后，即可正常的 android 操作。Android 系统上配置了电容屏，用户可以像操 作手机一样操作 android 系统。启动完毕之后，即可开始功能模块的测试。Android 测试方式请参考 《MY-I.MX6-DEMO-V2.2 Android 测试手册》 <br>
<span style="background:#CCCCCC">after starting up,there will be a logo booting,if the starting up logo can't be displayed normally,please turn off power for 3 seconds,re-start up and wait untill the system is started up,enter android interface,then android operations can be done normally.capacitor screen is configured in android system,users can operate android system as they operate mobile phones.after the booting,test for function module can be conducted. test method for android can be refered to 《MY-I.MX6-DEMO-V2.2 Android test manual</span><br>
