<li>If you are compiling the server version of the image, you can also choose to compile the Standard version or the Minimal version. The Minimal version will have much less pre-installed software than the Standard version ('''please do not choose the Minimal version without special needs, because many things are not pre-installed by default. Some functions may not be available''')</li></ol>

</div></ol>

<li>If you are compiling a desktop version of the image, you also need to select the type of desktop environment. Currently, only XFCE is maintained, so please select an XFCE type desktop.</li></ol>

<li>Then the compilation of the linux image will begin. The general process of compilation is as follows</li></ol>

::a. Initialize the compilation environment of Ubuntu PC and install the software packages required for the compilation process.

::b. Download the source code of u-boot and linux kernel (if already cached, only update the code)

::c. Compile u-boot source code and generate u-boot deb package

::d. Compile linux source code and generate linux-related deb packages

::e. Make the deb package of linux firmware

::f. Make the deb package of orangepi-config tool

::g. Create a deb package with board-level support

::h. If you compile the desktop version image, you will also create a desktop-related deb package.

::i. Check whether rootfs has been cached. If not, re-create rootfs. If it has been cached, decompress it directly and use it.

::j. Install the deb package generated previously into rootfs

::k. Make some specific settings for different development boards and different types of images, such as pre-installing additional software packages, modifying system configurations, etc.

::l. Then create the image file and format the partition. The default type is ext4.

::m. Then copy the configured rootfs to the mirror partition.

::n. Then update initramfs o. Finally, write the bin file of u-boot into the image through the dd command.
