    2. Deploy development environment 2. Deploy development environment Before the development, you need to install the Linux operating system on the PC. It is recommended to use the Ubuntu 16.04 64bit distribution, 8G memory, and more than 500G free hard disk. Connect the network cable and configure the network. For subsequent operations, you need to connect to the Internet to install or download related software packages. You can also refer to the official NXP document <Android_User's_Guide.pdf>. Repalce the Ubuntu sources-list Notice that this only applies to the developer in china. If you are in china ,the tuna resource should instead of the default. The website is as follows： https://mirrors.tuna.tsinghua.edu.cn/help/ubuntu/ Choose 16.04 ，and then copy the contents to update /etc/apt/source.list . Operating procedures ： 1.Backup the default file cp /etc/apt/sources.list /etc/apt/sources.list-bak 2.Copy contents from the tuna 16.04 column to /etc/apt/sources.list file. 3.Update source apt-get update PS: If error happens to appstream3 ,you can remove the package first and then update. apt-get remove libappstream3 apt-get update Host packages Essential Yocto Project host packages are: sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib build-essential chrpath socat libsd l1.2-dev u-boot-tools sudo apt-get install libsdl1.2-dev xterm sed cvs subversion coreutils texi2html docbook-utils python-pysqlite2 help2man make gcc g++ desktop-file-utils libgl1-mesa-dev libglu1-mesa-dev mercurial autoconf automake groff cu rl lzop asciidoc Set repo file The repo file is used to download resources, and it is located in 03-Tools/Repo for chinese, it should be installed on your computer by performing these step: mkdir ~/bin cp ~/03-Tools/Repo/repo ~/bin chmod a+x ~/bin/repo export PATH=~/bin:$PATH Please follow below steps instead of above ,if you are able to access google.
