IoT Yocto v22.0.1 - 2022 June 9

IoT Yocto v22.0.1 release is based on Yocto Dunfell 3.1 and Linux Kernel 5.10 LTS releases.

Supported Hardware 

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

Genio 350-EVK
Genio 1200-Demo Board (deprecated in v23.1)

Note

Please note that IoT Yocto plan to support MT8395(Genio 1200) staring from kernel v5.15. The current MT8395 configuration with Linux Kernel 5.10 in v22.0.1 release is for preliminary evaluation purposes only. In this release, MT8395 is using a different branch of Linux Kernel v5.10, linux-mtk-v5.10-i1200-dev (See link).

Feature Support Status - MT8395(Genio 1200)

Note

The support of MT8395 on IoT Yocto is under development. At the current alpha release, IoT Yocto enables the following features. Please note that IoT Yocto officially supported MT8395 on kernel v5.15. The v5.10 configuration is for preliminary evaluation purposes only.

These symbol represents the supporting status:

“V”: function eanbled by software and available on hardware board.
“O”: software integrated but cannot validate due to hardware board limitation.
“–”: not supported in this release; development on-going.
