2. Compile environment

• Only support Ubuntu 18.04. So you need to have a PC or virtual machine installed with Ubuntu 18.04.

3. Download the source code

• First download the OrangePi_Build, which can be used to download all the linux sdk for the Orange Pi development board.

git clone https://github.com/orangepi-xunlong/OrangePi_Build.git

• Enter the OrangePi_Build and run Build_OrangePi.sh.

$ cd OrangePi_Build
$ ./Build_OrangePi.sh

• First, you need to enter the root password for your ubuntu18.04.

Note that you are not entering root, but the password for root.

• Follow the prompts to continue, and finally select the model of your Orange Pi development board.

• If more than one kernel is supported for the Orange Pi board, you will also be prompted to select the kernel version for the board.

• Press enter key, OrangePi_Build will download the corresponding linux sdk based on your choice. It may take some time, so please be patient. After this finishes, you will get a new folder outside the OrangePi_Build:

Board model	Folder name
OrangePi Win/WinPlus	OrangePiA64
OrangePi OrangePi RK3399	OrangePiRK3399
OrangePi 2G-IOT/I96	OrangePiRDA
OrangePi 3G-IOT	OrangePi3G-iot
OrangePi 4G-IOT	OrangePi4G-iot

• This new folder is the downloaded linux sdk, mainly contains:

build.sh -> scripts/build.sh    Start the compile and select different features
external                        Sys_config.fex and the rootfs configuration files and others
kernel                          Linux kernel source directory
scripts                         Directory of all compiled scripts

$ cd OrangePiH3   //For different sdk, the name will be different.
$ ./build.sh
