= '''Prepare development board kits''' =
----
Development board kits consist of development board and its accessories.<br>
== '''Development board''' ==
Development board consist of following components:<br>

* MYZR-RK3288-CB314 (core board),one unit<br>

* MYZR-RK3288-MB314 (bottom board),one unit<br>

* Circuit board of screen panel,one unit<br>

* Crystal liquid screen,one piece<br>

* Touch screen,one unit<br>

== '''Development board accessory''' ==

Development board accessories include: <br>

* Adaptor,one unit<br>

* USB download cable,one piece<br>

* Internet cable,one piece<br>

* Serial line,one piece<br>

= '''Overview of development board interface''' =
----
Before starting the development board, we need to recognize some interfaces and connect them to the computer correctly.Here I first know the interface of MYZR-RK3288-MB314 .<br>

= '''Fast boot development board''' =
----
1）Skip to "off power switch" and "connect power line" in the section "connection between development board and computer". <br>

2）Skip to "power the development board" in the section "start the development board" and proceed from there. <br>

Note: the development board is not connected to the computer in the fast start mode, but the system start state can be seen from the LCD screen.<br>

== '''Development board is connected to the computer''' ==
Because in many cases we need to connect the development board to the computer, the following describes how the development board connects to the computer.<br>

=== '''Power switch off''' ===
1) Before connecting the development board to the computer, we need to check the power switch status of the development board and ensure that the power switch is disconnected.<br>

2) The way to keep the POWER switch on the development board in a disconnected state is to press the POWER switch on the development board (the MAIN POWER SW shown in the drawing on the front of the development board) to a disconnected state (-- : close, O: disconnect).<br>

=== '''Connection of serial lines''' ===
Connect one end of the serial port line to the DEBUG UART interface on the front of the development board, and the other end to the computer.<br>

Introductions：
1)If the computer does not have a serial port, you need to prepare your own USB cable and connect it.<br>

2)If there is no connection to the serial port line, you will not be able to interact with the development board in a serial port manner.However, it does not affect the starting and burning system of the development board.<br> 

== '''Serial port terminal tool configuration''' ==

1）Find the port number we use on the computer through the Windows device manager.<br>

2）Configure the parameters of the serial port terminal tool.<br>

::The SecureCRT & USB serial port 3 example configuration is as follows：<br>

== '''Network connection''' ==

Connect one end of the wire to the 1000M or 10M/100M Ethernet interface on the front of the development board, and insert the other end of the wire into the computer's network port.<br>

== '''USB download the connection''' ==

Connect one end of the USB cable to the OTG interface on the front of the development board, and insert the other end into the USB interface of the computer.<br>

== '''Connect the power cord''' ==

Connect one end of the power cord to the DC_5V_IN interface on the front of the development board, and one end to the power socket.<br>

== '''Start the development board''' ==
1)After working in sequence in "development board to computer connection", our development board to computer connection has been completed.<br>

2)To enable the development board to start up, we need to power the development board.<br>

3)Press the MAIN POWER SW to the closed state (-- : close, O: disconnect) on the front of the development board POWER switch.<br>

4)Then hold down the SLEEP WAKE button on the front of the development board until the LED light of the development board lights up.<br>

== '''Observe booting condition''' ==

=== '''Serial port terminal dynamics''' ===

You can see the information about booting process outputed during the course of development board booting through serial port terminal.<br>

:After starting, the serial port printing information is as follows:<br>

=== '''Display status''' ===

If the LCD is properly connected, you will see an output image of the display during the startup of the development board.<br>
