Issue with HMI SDK v3.5.0.0 Toolchain Installer

Updated: September 18, 2026

Depending on the host PC environment, the HMI SDK v3.5.0.0 toolchain installer may fail and terminate with an error. In some cases, the installation may appear to complete successfully without any visible errors. However, certain internal toolchain configuration updates may not be applied, resulting in an incomplete installation. This issue only affects the installation process of the SDK toolchain used to build applications and does not impact the SD card image.
To avoid this issue, please use the HMI SDK v3.5.0.1 toolchain installer. This issue has been resolved in HMI SDK v3.5.0.1 by incorporating the following upstream openembedded-core fix:

RZ/G HMI SDK version 3.5.0.0 is available.
