i.MX8M Plus Development Tools and dependencies

In this section, we are going to install some dependencies required for the development. In general terms, we are going to need:

1. Ubuntu 18.04 LTS as a development environment.
2. Yocto (Hardknott or Gatesgarth) as the main development tool.
3. Python for scripting.
4. GNU gcc/g++ compiler.

Specific dependencies

Once in Ubuntu, install some of the required dependencies with the commands below:

sudo apt-get install gawk wget git diffstat unzip texinfo gcc-multilib \
build-essential chrpath socat cpio python python3 python3-pip python3-pexpect \
xz-utils debianutils iputils-ping libsdl1.2-dev xterm

sudo apt-get install autoconf libtool libglib2.0-dev libarchive-dev python-git \

libncurses5 libncurses5-dev libncursesw5-dev libelf-dev zlib1g-dev bc rename bmap-tools

Installing and Configuring 'repo'

In order to get the NXP-based images, we are going to need repo, so configure it by following the next steps:

In case you do not have bin directory at $HOME, please create it please:

mkdir ~/bin

For downloading 'repo' use curl by executing the following command:

curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo

Give 'repo' execution permissions by doing:

chmod a+x ~/bin/repo

If you had to make the bin directory, please add this folder to the $PATH environment variable:

export PATH=~/bin:$PATH
