Abstract
Description
上記課題を解決するために本発明は、情報処理装置と、前記情報処理装置を外部からオンラインでデバッグするデバッグ装置とを有するオンラインデバッグシステムであって、前記情報処理装置は、記憶装置が記憶するデータを取得するために前記記憶装置に接続される接続端子を有し、前記情報処理装置は、該情報処理装置で実行されるソフトウェアを外部からの指示に基づいてデバッグするデバッグ実行部と、前記記憶装置から読み込んだ前記データを有効化させるデータ展開部とを有し、前記記憶装置が記憶する前記データは、前記デバッグ実行部に前記接続端子を介して外部と通信させるための通信ドライバ群を有し、前記接続端子に接続された前記記憶装置から前記データ展開部が前記通信ドライバ群を読み出して有効化すると、有効化された前記通信ドライバ群は、前記接続端子に接続されて前記情報処理装置の外部から指示を伝達する前記デバッグ装置を、前記デバッグ実行部と通信可能にする。
このような構成によれば、記憶装置とデバッグ装置との管理を容易にすることができるようになる。
このような構成によれば、一般的な規格に基づいた通信経路により、情報処理装置と記憶装置とデバッグ装置の間の通信がなされるようになるので、情報処理装置に接続可能なデバッグ装置の制約が少なくなる。これにより、このような情報処理装置のオンラインデバッグシステムの利用価値が高められる。
このような構成によれば、オンラインデバッグシステムを、車両に搭載されるナビゲーションシステムなどの車載情報処理装置をオンラインデバッグするように適用することができる。よって、カーディーラなどによって、ナビゲーションシステムをオンラインデバッグなどすることが可能にもなる。これにより、ユーザの感じる情報処理装置の違和感などに迅速に対応することが可能となり、情報処理装置のオンラインデバッグシステムの利便性の向上などが図られるようになる。
本発明にかかる情報処理装置のオンラインデバッグシステムの構成について図1~図4に従って説明する。
図5のフローチャートに示すように、ナビゲーションシステム20は、USBプラグ27にUSBメモリ40が挿入されたことをUSBホスト26により検出すると(図5のステップS10)、データ展開部24によりUSBメモリ40から検索テーブル41を取得する(図5のステップS11)。このとき、図6の通信経路図に示すように、ナビゲーションシステム20とUSBメモリ40との間では、記憶装置用ドライバ25、USBホスト26、及びUSBハブ30の第1の接続端子30A(Aプラグ)とによって構成される第1通信経路40Rにより、データ通信が可能となる。
(1)ナビゲーションシステム20は、デバッグ装置50との接続に用いられる端子であるUSBプラグ27を利用して、デバッグ装置50の利用時にUSBメモリ40から通信ドライバ群115を読み出し有効化する。すなわち、ナビゲーションシステム20が通信ドライバ群115の実行に要する領域は、デバッグ装置50の利用時にのみ、デバッグ用通信経路(第1通信経路40Rと第2通信経路50R)として確保されるようになる。これにより、ナビゲーション動作を行う製品として出荷時や通常使用時には開発用のデバッグ用通信経路などが取り除かれたナビゲーションシステム20にあっても、ナビゲーションシステム20で実行するソフトウェアのデバッグを必要に応じて随時可能とする。つまりナビゲーションシステムそのものとしては、デバッグ装置50の接続に要する通信経路を含めたインタフェース等を普段はナビゲーションシステム20から割愛することができるようになる。
なお上記各実施形態は、以下の態様で実施することもできる。
・上記実施形態では、USBメモリ40とデバッグ装置50とでUSBホスト26を共用する場合について例示した。しかしこれに限らず、USBメモリとデバッグ装置とにそれぞれ各別のUSBホストでナビゲーションシステム20が対応するように構成してもよい。例えば、図8に示すように、ナビゲーションシステム20が、USBメモリ40に接続される第1USBインタフェース27Aと、デバッグ装置50に接続される第2USBインタフェース27Bとを有してもよい。この場合に第1USBインタフェース27Aは、USBメモリ40と記憶装置用ドライバ25の間を中継し、第2USBインタフェース27Bは、デバッグ装置50とシリアル通信ドライバ23の間を中継する。この場合にはナビゲーションシステム20は、USBメモリ40から取得した通信ドライバ群を、第2USBインタフェース27Bに対して有効化させればよい。またナビゲーションシステム20は、USBメモリ40が第1USBインタフェース27Aから取り外しされたことを検出すると、第2USBインタフェース27Bを介した通信経路を切断することもできる。これにより、情報処理装置のオンラインデバッグシステムの構成の自由度が高められる。
