AIoT Yocto v22.1 - 2022 Aug 03

AIoT Yocto v22.1 release provides two hardware configurations supported by separate software configurations:

  • Genio 1200 lands on Linux Kernel 5.15 (mtk-v5.15-dev) and Yocto Kirkstone.

  • Genio 350 is supported by Linux Kernel 5.10 (mtk-v5.10) and Yocto Dunfell, same as the previous release.

We plan to upgrade the support for Genio 350 to Kernel 5.15 and Yocto Kirkstone in future releases.

Supported Hardware

This release supports following boards based on MT8365(Genio 350) and MT8395(Genio 1200) MediaTek SoC families:

Notable New Features and Changes in v22.1

  • MT8395 SoC and Genio 1200-demo board support on Linux kernel version 5.15, notably:

    • AI Processor Unit(APU) support through MediaTek Neuron SDK for MT8395

    • Hardware video decoder and encoder support for MT8395

    • HDMI & DisplayPort support for MT8395

    • Wi-Fi & Bluetooth connectivity with external M.2 MT7921 PCIe module (AzureWave AW-XB468NF) for Genio 1200-demo board

  • In this release, the template configuration is builds Public images that skips access controlled repositories. Please update the NDA_BUILD config if you have access to proprietary source packages.

Public & Private Prebuilt Images

AIoT Yocto v22.1 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 AIoT 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 access permissions to AIoT GitLab group. This lacks some proprietary features and also some proprietary components are provided in binary-only format.

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

  • Xtensa-ANN support on Genio 350-EVK

  • Neuron SDK support on Genio 1200-demo

  • MT7663 proprietary Wi-Fi driver on Genio 350-EVK

  • eFuse writer

Software Packages

Important

Please read and agree AIoT Software License Agreement before accessing or using AIoT Yocto software. If you do not agree to the terms and conditions of AIoT Software License Agreement, you must not access or use the software.

To download AIoT Yocto recipes for v22.1 release, determine the SoC and board hardware you’d like to use first:

Genio 1200

For MT8395 & Genio 1200-demo, use the following manifest:

repo init -u https://gitlab.com/mediatek/aiot/bsp/manifest.git -b refs/tags/rity-kirkstone-v22.1

Genio 350

For MT8365 & Genio 350-EVK, use the following manifest:

repo init -u https://gitlab.com/mediatek/aiot/bsp/manifest.git -b refs/tags/rity-dunfell-v22.1

Private (NDA) configuration

In v22.1 release configures to public image by default (NDA_BUILD = "0"). To build the private image configuration, set the configuration flag NDA_BUILD = "1" in local.conf:

echo NDA_BUILD = \"1\" >> ${BUILD_DIR}/conf/local.conf

Before building with the bitbake commands.

Please refer to Get Started with AIoT Yocto for detailed steps.

Tools

aiot-tools is released to load built images to the development boards. Please refer to Get Started with AIoT Yocto and AIoT Tools for detailed usage.
