<li><p>Download the compressed Linux operating system image file you want to burn from [http://www.orangepi.org/html/hardWare/computerAndMicrocontrollers/service-and-support/Orange-Pi-CM4-1.html '''Orange Pi's data download page'''], and then use the decompression software to decompress it. Files ending with "'''.img''' "in the decompressed files are the image files of the operating system, and the size is generally more than 2GB</p>
<p>The following command is used to decompress the compressed package ending in 7z</p>

<p>test@test:~$ '''7z x Orangepicm4_1.0.0_debian_bullseye_desktop_xfce_linux5.10.160.7z'''</p>
<p>test@test:~$ '''ls Orangepicm4_1.0.0_debian_bullseye_desktop_xfce_linux5.10.160.*'''</p>
<p>Orangepicm4_1.0.0_debian_bullseye_desktop_xfce_linux5.10.160.7z Orangepicm4_1.0.0_debian_bullseye_desktop_xfce_linux5.10.160.sha #Checksum file</p>
<p>Orangepicm4_1.0.0_debian_bullseye_desktop_xfce_linux5.10.160.img #Image file</p>|}</li>
<li><p>After decompressing the image, you can first use the '''sha256sum -c *.sha''' command to calculate whether the checksum is correct, if the success indicates that the downloaded image is not wrong, you can rest assured to burn to the TF card, if the '''checksum does not match''' that there is a problem with the downloaded image, please try to re-download</p>
