SecureCRT & USB串口3 示例配置如下：SecureCRT & USB serial port3 configuration example as below: 网线的连接(Connection of network cable)将网线一端插入开发板的U12（开发板正面图的图示18），网线另一端插入计算机的网口。Connect one end of network cable with development board U12（icon 18 on front view），another end inserted into lan port of computer. USB下载线的连接(connection of USB download line)将USB线一端连接到开发板的J5（开发板正面图的图示22），另外一端插入计算机的USB接口。Connect one end of USB line with development board J5（icon 22 on front view），another end inserted into USB port of computer. 连接电源线(connection of power supply cable)将电源线一端连接到开发板的J4（开发板正面图的图示29），一端连接电源插座。Connect one end of power supply cable with development J4（icon 29 on front view），another end connected with power supply socket. 开发板的启动(booting of development board)在“开发板与计算机的连接”中按照顺序进行操作后，我们的开发板与计算机的连接已经完成了。要使开发板启动，我们需要为开发板上电。After all the operations in "connection between development board and computer"were completed in order，the connection of development board with computer is ready. To boot the board, we need to power on the development board. 为开发板上电(power on development board)将开发板电源开关J3（开发板正面图的图示28）按到闭合状态（—：闭合，O：断开）。Press development board power supply switch J3（icon 28 on front view）to closed status（—：closed，O：off）观察启动状况(observe booting condition)U-boot启动动态(U-boot dynamics)会看到液晶屏被点亮，并显示 Freescale 与 明远智睿 的LOGO。You will see the LCD screen lit up and display Freescale and MYZR’s LOGO. 串口终端动态(serial port terminal dynamics)会看到计算机的串口终端有开发板启动过程中输出的启动过程信息。You can see the information about booting process outputed during the course of development board booting through serial port terminal.内核启动动态(kernel booting dynamics)内核启动到一定阶段后，在液晶屏上会看到小企鹅。After the kernel boots at a certain stage, you can see the penguins on the LCD screen. < br >系统动态(system dynamics)1）Linux系统(Linux system) 系统启动完成后，在液晶屏上会保持小企鹅的显示。After the system booting is completed, the little penguin will be still displayed on the LCD screen. 串口输出信息会提示用户按下“Enter” ，这时候按下计算机上的“Enter”即可进入系统。示例如下：The serial port output message prompts the user to press " Enter " , and then press " Enter " on the computer to enter the system . For example: 2）Linux QT系统(Linux QT system)系统启动完成后，开发板会运行一个QT的示例程序，在液晶屏上可以看到QT示例程序的运行。After the system booting is completed, the development board will run a QT sample program, and you can see the QT sample program running on the LCD screen. < br >3）Ubuntu系统(Ubuntu system)系统启动完成后，在液晶屏上可以看到Ubuntu系统界面。After the system booting is completed, you can see the interface on the LCD screen.
