Yocto Project Build

Start and enter a container,

docker start my_container_for_20.04
docker exec -it my_container_for_20.04 /bin/bash

According to the Linux Startup Guide, additional packages need to be installed inside the Docker container by using the command below:

$ sudo apt-get update
$ sudo apt-get install gawk wget git-core 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 p7zip-full libyaml-dev \
libssl-dev bmap-tools

Install additional packages such as Cmake and Meson that may be used later:

sudo apt update
sudo apt install software-properties-common

sudo apt-add-reporitory 'deb https://apt.kitware.com/ubuntu/ bionic main'
sudo apt update
sudo apt install cmake

sudo apt install meson ninja-build

Please follow the previous tutorial to prepare the Renesas RZ/G2L board for Yocto build step by step.

Please note that each time, we enter the container, it's necessary to run the code below to set the environment variables.

cd <work dir> 
TEMPLATECONF=$PWD/meta-renesas/meta-rzg2l/docs/template/conf/ source poky/oe-init-build-env build

There are some choices for the build option, it's recommended to use the most complete build option as below to start the Yocto build.

MACHINE=smarc-rzg2l bitbake core-image-qt

After finishing the Yocto Build, check the output directory as shown below:

cd build/tmp/deploy/images/smarc-rag2l/

The output of the build are

core-image-qt-smarc-rzg2l.wic.gz
core-image-qt-smarc-rzg2l.wic.bmap

Exit from the Docker container and copy the output file into the SD card using the command below:

sudo bmaptool copy core-image-qt-smarc-rzg2l.wic.gz /dev/sda

After that, remove the SD card, insert it to RZ/G2L and boot up. Now you can click on the Qt Demo items or open the terminal then input some Linux commands for test.
