===Setup Development Environment===
====Method 1: Using docker to cross-compile====
Please refre to [https://github.com/friendlyarm/docker-cross-compiler-novnc docker-cross-compiler-novnc]
====Method 2: Setup build environment on the host machine====
=====Install required packages=====
Install and run requirements ubuntu 20.04, install required packages using the following commands:
<syntaxhighlight lang="bash">
sudo apt-get -y update
sudo apt-get install -y sudo curl
sudo bash -c \
  "$(curl -fsSL https://raw.githubusercontent.com/friendlyarm/build-env-on-ubuntu-bionic/master/install.sh)"
</syntaxhighlight>
The following cross-compilers will be installed:
{| class="wikitable" 
|-
! Version
! Architecture
! Compiler path
! Purpose
|-
| 4.9.3
| armhf
| /opt/FriendlyARM/toolchain/4.9.3
| Can be used to build 32-bit ARM applications
|-
| 6.4
| aarch64
| /opt/FriendlyARM/toolchain/6.4-aarch64
| Can be used to build kernel 4.4
|-
| 11.3
| aarch64
| /opt/FriendlyARM/toolchain/11.3-aarch64
| Can be used to build kernel 4.19 or higher and U-Boot
|}
=====Setting the compiler path=====
Based on the table in the previous section, select the appropriate version of the compiler and add the compiler's path to PATH. For example, if you want to use the 11.3 cross-compiler, edit ~/.bashrc using vi and add the following content to the end:
<syntaxhighlight lang="bash">
export PATH=/opt/FriendlyARM/toolchain/11.3-aarch64/bin:$PATH
export GCC_COLORS=auto
</syntaxhighlight>
Run the ~/.bashrc script to make it effective in the current commandline. Note: there is a space after ".":
<syntaxhighlight lang="bash">
. ~/.bashrc
</syntaxhighlight>
To verify if the installation was successful：
<syntaxhighlight lang="bash">
$ aarch64-linux-gcc -v
Using built-in specs.
