3. G2L00 Yocto Introduction
This section provides instructions for building and Yocto systems on the
G2L100. If you need the source code, please contact us and we will publish the
source code. Let's use our server as an example to compile.
3.1 Building Environment
This release note describes the contents, building procedures and important points of the G2L Board
Support Package (hereinafter referred to as “BSP”)
The recommended environment for BSP is shown below. The equipment and
software used in this environment are listed in the following table.

3.2 Building Instructions of a BSP
3.2.1 Building images to run on the board
This section describes the instructions to build the BSP. Before starting the
build, run the command below on the
Linux Host PC to install packages used for building the BSP.
Please refer to the URL below for detailed information:
•https://docs.yoctoproject.org/3.1.5/brief-yoctoprojectqs/brief-
yoctoprojectqs.html
Run the commandsbelow and set the user name and email address before
starting the build procedure. Without this setting, an error occurs when
building procedure runs git command to apply patches.
1) Create a working directory (user_work) at your home directory, and
decompress Yocto recipe package
Run the commands below. Copy the compressed Yocto recipe package files
(rzg2l_bsp_v1.0.tar.gz) into your home directory prior to this step.
Note) When you use the WS1 version of the G2L LSI, please refer to the Section 3.2.3 Notes - (1) and apply the
patches before the step (4) in the section 3.2.1.
2) Setup a build environment
Run the commands below. The environment to build is set by the source
command.
$ sudo apt-get update
$ sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib \
build-essential chrpath socat cpio python3 python3-pip python3-pexpect xz-utils \
debianutils iputils-ping python3-git python3-jinja2 libegl1-mesa libsdl1.2-dev \
pylint3 xterm
$ git config --global user.email "[e-mail]"
$ git config --global user.name "Your Name"
$ mkdir ~/user_work
$ cd ~/user_work
$ tar zxvf ~/rzg2l_bsp_v1.0.tar.gz

3) Prepare the default configuration files for the target board
Run the commands below.
4) Start a build
Run the commands below to start a build. Please connect the Linux Host PC to
the network when building. Building an image can take up to a few hours
depending on the user’s host system performance.
After the build is successfully completed, a similar output will be seen, and the
command prompt will return.
3.2.2 Building SDK
To build Software Development Kit (SDK), run the commands below after the
steps (1) – (4) of section 3.2.1 are finished.
The SDK allows you to build custom applications outside of the Yocto
environment, even on a completely different PC. The results of the commands
below are ‘installer’ that you will use to install the SDK on the same PC, or a
completely different PC.
For building general applications:
The resulting SDK installer will be located in build/tmp/deploy/sdk/
The SDK installer will have the extension .sh
To run the installer, you would execute the following command:
$ cd ~/user_work
$ source poky/oe-init-build-env
$ cd ~/user_work/build
$ cp ../meta-rzg2/docs/template/conf/minimal/smarc-rzg2l/*.conf ./conf/
$ bitbake core-image-minimal
NOTE: Tasks Summary: Attempted 7427 tasks of which 16 didn't need to be rerun
and al l succeeded.
$ cd ~/user_work/build
$ bitbake core-image-minimal -c populate_sdk
