Overview¶

The HMI SDK provides a Yocto-based Linux environment with development tools, system libraries, graphics and multimedia support, and HMI frameworks such as HTML5, LVGL, or Flutter, making it easy to create and run HMI applications.

The HMI SDK is specifically designed for the supported RZ/G EVKs and includes fixed Linux components. The source is also provided for further development and customization.

For an easy setup and quick access to the out-of-the-box demo applications, please refer to Getting Started. For a customized Linux environment—such as modifying the memory map or adding support for your own board, please refer to Building the HMI SDK with Yocto.

Supported Boards¶

• RZ/G3E Evaluation Board Kit (RTK9947E57S01000BE)

SDK Components¶

HMI SDK provides the following packages:

• HMI SDK Package -eSD Boot Image & Toolchain Installer

  This package lets you get started right away. You can create a bootable microSD card for the EVK, set up the Linux environment, run the prebuilt demo applications, and build sample HMI applications using the included toolchain installer.
  
  Please go to Getting Started to get started with this HMI SDK Package.

  
  

• HMI SDK Yocto Build Package -Yocto Recipes & Pre-built Binary for QSPI Boot

  This package is for when you want more flexibility. You can build and customize the entire HMI SDK from source. You can also try other boot modes such as QSPI or eMMC, in addition to eSD.

  • Source Code -Supplementary for HMI SDK Yocto Build Package
    Note that this is optional; the supplementary source code used in the Yocto build is provided for offline builds or as a backup if online fetching fails.

  
  Please go to Building the HMI SDK with Yocto to get started with this HMI SDK Yocto Build Package (and Source Code).

The packages are designed for specific board models, while the source code is universal and can be used across all boards.

HMI Application Contents¶

HMI Demo Applications

When the HMI SDK Linux system boots, the Demo Application Launcher starts automatically. The pre-installed demo applications can then be launched from the Demo Application Launcher—for example, the Chromium Home Panel Demo shown below.

Follow the instructions under Demo Applications in the HMI Applications section to view these demos. They come as pre-built binaries, with source code also provided in the table below:

HMI Sample Applications

The sample applications are not pre-built and require additional building and deployment. Follow the instructions under Sample Applications in the HMI Applications section to try them, with source code also provided in the table below:
