Zephyrのwestでtflite-microをビルドしたい場合
Zephyr(RTOS)のようなEdge(エッジ)環境でAIを動かしたい場合です。
ビルドする際にtflite-microを含める必要が出てきます。
但し、何も設定しないで、ビルドすると下記のようなエラーがでます。

デフォルトだとtflite-microの環境には(重いためか)、入っていません。
このエラーの対応で、Zephyrのmanifestにどのように記載するかを紹介します。
「Zephyr(west)」と「nRF Connect」の2つの環境で紹介します
Zephyr
Zephyr(West)の環境では、下記を実行すればOKです
west config manifest.project-filter -- +tflite-micro
west update
west update
参考
https://wiki.seeedstudio.com/XIAO-nRF52840-Zephyr-RTOS/#tflite---hello-world
nRF Connect
NordicのnRF Connectの環境についてです。
インストールしたnRF Connectのwest.ymlを開きます。
筆者の例だと、C:\ncs\v*.* .*\nrf\west.yml の name-allowlist:にtflite-microを追加します
その後、nRF環境でwestをアップデートします。
west update
参考
https://devzone.nordicsemi.com/f/nordic-q-a/106613/ncs-2-5-hello-world-tensorflow-example
Hello Worldでテスト
Zephyr公式のサンプルにある、tflite-macroでテストします。
https://github.com/zephyrproject-rtos/zephyr/tree/main/samples/modules/tflite-micro/hello_world
今回は、nRF ConnectでXIAO nRF54L15 Senseのボード向けにビルドしています
問題なくビルド出来ます。
tflite-macroが入るので、ビルドが長めになります

まとめ
Zephyr(RTOS)のようなEdge(エッジ)環境でAIを動かしたい場合です。
ビルドする際にtflite-microを含めたい必要が出てきます。
Zephyrのmanifestにどのように記載するかを紹介しました。
