<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 [[\lOrange Pi 3B#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 [[\lOrange Pi 3B#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 [[\lOrange Pi 3B#uploading files to 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></ol>

'''How 1. For the method of using the serial port to log in to enter the command line of terminal, please refer to the instructions in the section on [[Orange Pi 3B#how to use the debugging serial port|how to use the development board Linux system?debugging serial port]].'''

# '''For the method of using the serial port to log in to the terminal, please refer to the instructions in the section on [[\l|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 [[\lOrange Pi 3B#SSH remote login to the development board|SSH remote login to the development board]].'''# '''If HDMI, LCD and other display screens are connected, you can open a command line terminal on the desktop.'''

<li>Next, we first use the following command to confirm the device node of eMMC</li></ol>

'''<span style="color:#FF0000">/dev/mmcblk0</span>'''|}</ol>

<li>Then we can use the dd command to clear the eMMC. Note that after the '''of=''' parameter, please fill in the output result of the above command</li></ol>

{| class="wikitable" style="width:800px;" |-| orangepi@orangepi:~/Desktop$ '''sudo dd bs=1M if=/dev/zero of=<span style="color:#FF0000">/dev/mmcblk0 </span> count=1000 status=progress'''

<li><p>Please do not copy the Linux image name in the following command, but replace it with the actual image name (because the version number of the image may be updated).</p></li></ol></li></ol>{| class="wikitable" style="width:800px;" |-| '''sudo dd bs=1M if=Orangepi3b_x.x.x_debian_bullseye_desktop_xfce_Linux5.10.160.img of=<span style="color:#FF0000">/dev/mmcblk0 </span> status=progress'''

<li>After successfully burning the Linux image of the development board to the eMMC, you can use the '''poweroff''' command to shut down. Then please pull out the TF card, and then short press the power button to turn on, and then the Linux system in the eMMC will be started.</li>{| class="wikitable" style="background-color:#ffffdc;width:800px;" |-| </olbig> '''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 [[\lOrange Pi 3B#using RKDevTool to clear SPIFlash|the method of using RKDevTool to clear SPIFlash]].'''</big>|}</ol>
