→Use the dd command to burn the Linux image into eMMC
<ol start="2" style="list-style-type: decimal;">
<li><p>Using the dd command to burn the Linux image to eMMC needs to be completed with the help of a TF card, so first you need to burn the Linux image to the TF card, and then use the TF card to start the development board to enter the Linux system. For the method of burning the Linux image to the TF card, please refer to the instructions in the two sections of [[Orange Pi 3B#Method of burning the Linux image to the TF card based on the Windows PC|'''the method of burning the Linux image to the TF card based on the Windows PC''']] and [[Orange Pi 3B#Method of burning the Linux image to the TF card based on the Ubuntu PC|'''the method of burning the Linux image to the TF card based on the Ubuntu PC''']].</p></li><li><p>After using the TF card to start the Linux system, we first upload the decompressed Linux image file (Debian, Ubuntu image or OPi Arch image downloaded from the official website) to the TF card. For the method of uploading the Linux image file to the development board, please refer to the description in the section of [[Orange Pi 3B#The method of uploading files to the Linux system of the development board Linux system|'''the method of uploading files to the development board Linux system''']].</p></li>
<li><p>After uploading the image to the Linux system of the development board, we enter the storage path of the image file in the command line of the Linux system of the development board. For example, I store the Linux image of the development board in the '''/home/orangepi/Desktop''' directory Download it, and then enter the '''/home/orangepi/Desktop''' directory to see the uploaded image file.</p></li>
<big>'''How to enter the command line of the development board Linux system?'''
'''1. For the method of using the serial port to log in to the terminal, please refer to the instructions in the section on [[Orange Pi 3B#how How to use the debugging serial port|how to use the debugging serial port]].'''
'''2. Use ssh to remotely log in to the Linux system, please refer to the instructions in the section of [[Orange Pi 3B#SSH remote login to the development board|SSH remote login to the development board]].'''
'''3. If HDMI, LCD and other display screens are connected, you can open a command line terminal on the desktop.'''</big>

<big>'''Note, after burning the image into eMMC, if the test finds that it cannot be started, please clear the SPIFlash and try again. For the method of clearing SPIFlash, please refer to [[Orange Pi 3B#using Using RKDevTool to clear SPIFlash|the method of using RKDevTool to clear SPIFlash]].'''</big>
