ビルド・動作確認方法

プロジェクト設定では「\Application\_Exclude\IP」フォルダはビルド対象外に設定しています。以下のどちらかの方法で動作確認を行うサンプルアプリケーションを選択します。

  1. 「\_Exclude\IP」フォルダ下の対象テストサンプルファイルをビルド対象設定の「\Application」フォルダ下にコピーします。
  2. 「\_Exclude\IP」フォルダ下の対象テストサンプルファイルのみ「ビルド対象外」の設定を解除します。

各テストアプリケーションの動作確認方法はテストサンプルアプリケーションのヘッダのコメント情報を参照ください。

テスト環境の設定：

評価ボードのLANポートをテスト用パソコンに接続して、TCP/IPネットワーク通信が正常にできることを確認してください。

PC Setup

ネットワーク環境に合わせて評価ボード側のemNetスタックのコンフィグレーション設定を編集してください。
