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。

「\_Exclude\IP」フォルダ下の動作確認を行う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。
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。
