• A clear and concise description of what the bug is.
  On Windows trying to use customLaunchSetupCommands to configure a target launch on an embedded arm device I am getting the error message "Unable to start debugging. Specified argument was out of the range of valid values. PArameter name: arch".

This needs a cross compile project to repro and some setup for the embedded debugger. I have some projects that can be shared for the repro.

C/C++ 拡張機能の customLaunchSetupCommands の処理から始め、クロスコンパイルされた組み込み ARM プロジェクトとデバッガー構成を使用して Windows で問題を再現します。custom launch コマンドが無効な引数 "arch" のエラーなしでデバッグを開始できれば完了です。
