Overview

RZ/G HMI Software Development Kit (HMI SDK) is an HMI application development environment for Evaluation Board Kit of RZ/G series.

Since it contains Yocto Linux with bootloader, Linux Kernel, Cross Compiler, multimedia and graphics package, users can develop HMI Applications easily and quickly with HMI SDK.

HMI SDK is specifically made for the supported Evaluation Board Kit with fixed Linux components. If you need to customize the Linux environment—such as modifying the memory map or developing support for your own board—you will need to build Yocto Linux from source.

For detailed instructions, please refer to How to build HMI SDK.

How To Build HMI SDK

Supported Boards

  • RZ/G2L Evaluation Board Kit (RTK9744L23S01000BE)
  • RZ/G2LC Evaluation Board Kit (RTK9744C22S01000BE)
  • RZ/G2UL Evaluation Board Kit (RTK9743U11S01000BE)

SDK Components

HMI SDK provides the following packages:

  • eSD boot image and toolchain installer package

    This package is the heart of HMI SDK. You can create a bootable microSD card, set up Linux environment on the EVK, and build sample applications.

  • Yocto recipe and pre-built binary image package

    This is an optional package. If you would like to build the HMI SDK from scratch, or you would like to try QSPI boot or eMMC boot (other than eSD boot mode), get this package.

  • Source code package

    When you build the HMI SDK from scratch, you can use source code in this package for offline building.

Except for the source code package, the packages are available for each EVK.

HMI Applications

HMI SDK provides HMI demos and sample applications.
These are available as both source code and prebuilt binaries, allowing you to run them on the board immediately and customize them as needed.
