Quick Setup

Quick Setup ###########

A Git repository is available that includes everything needed to test the Buildroot setup without following the guide. It is intended for testing purposes and can be used if you are already familiar with Buildroot concepts and architecture.

Get the repository

.. code-block:: bash

git clone --recurse-submodules https://github.com/lvgl/lv_buildroot.git

Build the image

.. code-block:: bash

./build.sh

At this point, you have an image that can be flashed on an SD and used.

Now build the SDK and install it

.. code-block:: bash

cd output
make sdk
mkdir -p ~/sdk
tar -xzf images/aarch64-buildroot-linux-gnu_sdk-buildroot.tar.gz -C ~/sdk

The SDK is installed. Compile the application.

.. code-block:: bash

cd ../application/lv_benchmark
source ../setup-build-env.sh
cmake -B build -S .
make -j $(nproc) -C build
cd ../..

Install the binary in the rootfs_overlay

.. code-block:: bash

cp application/lv_benchmark/bin/lvgl-app resources/board/rootfs_overlay/usr/bin/

Regenerate the image with the rootfs overlay updated.

.. code-block:: bash

cd output
make

Go to :ref:flash_the_image to test the system.
