RZ/G Family

Supported boards in the RZ/G Family:

  • RZ/G2L-EVKIT

  • RZ/G2UL-EVKIT

Run the Project

  • The RZ/G boards are MPUs with support for running Linux. Projects are built for them using a cross-compiler CLI toolchain SDK in a Linux PC environment (WSL, Docker, etc. can be used on Windows).

  • The G2L has a Wayland desktop and the project appears as a Wayland window. The G2UL does not have a desktop so the project is fullscreen and uses the fbdev driver.

  • The SDK currently uses LVGL v8.3 so this project uses this version to mirror the SDK version, even though LVGL is statically linked. You may try using newer versions of LVGL.

  • Clone the ready-to-use repository for your selected board:

    git clone https://github.com/lvgl/lv_port_renesas_rz-g2l-evkit --recurse-submodules

    Downloading the .zip from GitHub doesn't work as it doesn't download the submodules.

  • Follow the instructions in the project README.md to obtain the SD Card image and toolchain installer, build, and upload the project to the board.

  • Stop any automatically started demos (on G2UL run systemctl stop demo-launcher in the terminal).

  • Run the project

    ./lvgl_demo_benchmark

Modify the project

Open a demo

The entry point is contained in src/main.c.

You can disable the LVGL demos (lv_demo_benchmark()) (or just comment them out) and call some lv_example_...() functions, or add your custom code.

Configuration

Edit lv_conf.h and lv_drv_conf.h to configure LVGL. The board image contains LVGL and lv_drivers as dynamically linkable libraries. This project builds LVGL statically for customizability and to port the LVGL v9 benchmark LVGL v8.3.

Support

In case of any problems or questions open an issue in the corresponding repository.
