IoT Yocto v24.0 - 2024 July 1

IoT Yocto v24.0 release supports Genio SoC families based on Yocto Kirkstone and Linux 5.15. This page provides an overview of the major changes and new features in v24.0.

Supported Boards

This release supports following boards based on MT8365(Genio 350/G350), MT8370(Genio 510/G510), MT8390(Genio 700/G700), and MT8395(Genio 1200/G1200) MediaTek SoC families:

MACHINE name for bitbake

Genio 350-EVK(P1V3)

  • genio-350-evk

Genio 510-EVK(P1V2)

  • genio-510-evk

Genio 700-EVK(P1V3)

  • genio-700-evk

Genio 1200-EVK(P1V2)

  • genio-1200-evk (EMMC boot)

  • genio-1200-evk-ufs (UFS boot)

Important

The Genio 700-EVK has two hardware versions, P1V3 and P1V4. The major difference between them is the DSI display module. - Genio 700-EVK(P1V3) uses startek-kd070fhfid015 - Genio 700-EVK(P1V4) uses startek-kd070fhfid078, which shares the same DSI module as the Genio 510-EVK(P1V2) and Genio 1200-EVK(P1V2)

In this v24.0 release, the Genio 700-EVK(P1V4) (with the new DSI panel) is not yet fully supported. You may still use the Genio 700-EVK(P1V3) image on the Genio 700-EVK(P1V4), but the DSI panel won’t have screen display. The display support for the new DSI panel will be provided in the future as patch release.

IoT Yocto v24.0 is available in two different packages groups:

  • You don’t need a GitLab account to download both private and public prebuilt images, but you need to agree to the Software License Agreement.

  • You don’t need a GitLab account to build the public image configurations.

  • You need a GitLab account and contracts to MediaTek to access and build the private image.

Public images are built with packages that are available without explicit access permissions to the GitLab group. Some proprietary features are excluded, and some proprietary components are provided in binary-only format. You may find the binary modules and its licenseing in the last page of the IoT Yocto Feature Table (v24.0).

Private images, on the other hand, require access to private repositories in the GitLab group. In v24.0 release, the private image provides these additional features on top of the public configuration:

  • Security features on all Genio platforms, including:

    • eFuse writer and custom data field access

    • RPMB access API

  • ISP for RAW sensors and YUV sensors support on Genio 510, Genio 700 and Genio 1200

  • Xtensa-ANN support on Genio 350

  • MT7663 proprietary Wi-Fi driver on Genio 350

  • MT7663 BlueDroid support and proprietary Bluetooth driver on Genio 350

Online APU Inference through TensorFlow Lite Stable Delegate (Genio 510, Genio 700, Genio 1200)

Users can run AI inference on APU (VPU/MDLA) with the TFLite interpreter through the Stable Delegate interface.

  • Stable Delegate is still an experimental feature in the latest TensorFlow release (v2.16).

  • TFLite models are runtime-compiled through the TFLite interpreter, which can accept more operations than offline dedicated compilation.

  • Global fallback to TFLite-CPU for unsupported operations rather than full-graph rejection.

For details, please refer to ML Section.

Known Issues

Here are some known issues in the v24.0 release. These issues are under investigation and will be fixed in future patches.

  • After upgrading the ARM Mali GPU from DDK r43 to r48, the suspend power slightly increased by 5% on the Genio 510. The root cause is still under investigation.

  • The Genio 510/Genio 700/Genio 1200 camera rarely fails in a stress test environment (repeatedly opening/closing using a script).
