<div style="border:1px solid #000;background:#f1f1f1;">
test@test:~$ '''unzip balena-etcher-electron-1.5.109-linux-x64.zip'''<br>
Archive: balena-etcher-electron-1.5.109-linux-x64.zip<br>
inflating: balenaEtcher-1.5.109-x64.AppImage <br>
test@test:~$ '''ls'''<br>
'''balenaEtcher-1.5.109-x64.AppImage''' balena-etcher-electron-1.5.109-linux-x64.zip
</div>
<br>
6)Download the Linux operating system image file compression package you want to burn from the Orange Pi data download page, and then use the decompression software to decompress it. In the decompressed file, the file ending with ".img" is the operating system image file. The size is generally above 1GB<br>
<div style="border:1px solid #000;background:#f1f1f1;">
test@test:~$ '''ls Orangepi4_2.1.0_ubuntu_xenial_desktop_linux4.4.179'''<br>
Orangepi4_2.1.0_ubuntu_xenial_desktop_linux4.4.179.img<br>
Orangepi4_2.1.0_ubuntu_xenial_desktop_linux4.4.179.img.sha # Checksum file<br>
'''Orangepi4_2.1.0_ubuntu_xenial_desktop_linux4.4.179.img''' # Image file
</div>
<br>
7)After decompressing the image, you can first use the sha256sum -c *.sha command to calculate whether the checksum is correct. If the prompt indicates that the downloaded image is correct, you can safely burn it to the TF card. If the checksum does not match, it indicates There is a problem with the downloaded image, please try to download again<br>
<br>
<div style="border:1px solid #000;background:#f1f1f1;">
