Windows Mobile 6.5 Live Hardware Debugging Tools

Debugging software directly on physical Windows Mobile 6.5 hardware required a specialized combination of integrated development environments, software development kits, and tethering protocols. Because mobile processors like ARM differed substantially from desktop architectures, developers relied on a dedicated hardware communication pipeline to attach remote debuggers, deploy executables, inspect memory, and perform live step-through execution directly on tethered devices. This article details the primary software tools and frameworks that made real-time hardware debugging possible on the platform.

Microsoft Visual Studio 2008

Microsoft Visual Studio 2008 (Professional edition and higher) was the primary integrated development environment (IDE) for live step-through debugging on Windows Mobile 6.5 hardware. While Visual Studio 2005 also supported older versions of the mobile OS, Visual Studio 2008 provided the definitive tooling for Windows Mobile 6.5 through Service Pack 1.

Subsequent versions of the IDE, starting with Visual Studio 2010, discontinued support for Windows Mobile Smart Device projects and the .NET Compact Framework. Consequently, Visual Studio 2008 remained the industry standard for native C/C++ and managed code step-through debugging on physical Windows Mobile 6.5 devices.

Windows Mobile 6.5 Developer Tool Kit and SDKs

To bridge Visual Studio with Windows Mobile 6.5 hardware, developers installed the Windows Mobile 6.5 Developer Tool Kit, which extended the existing Windows Mobile 6 Professional and Standard SDKs.

These packages installed the device headers, libraries, and transport protocols necessary to connect to ARM-based physical devices over a local interface. They exposed the platform options in the Visual Studio target device dropdown, allowing developers to switch the target from an x86 software emulator to "Windows Mobile 6 Professional Device."

Windows Mobile Device Center and ActiveSync

Physical hardware connections required an underlying transport layer to route debugger traffic between the host workstation and the mobile unit.

  • ActiveSync: Used on host workstations running Windows XP.
  • Windows Mobile Device Center (WMDC): Replaced ActiveSync on Windows Vista and Windows 7.

These utilities managed the USB, serial, or Bluetooth tethering connection and established a virtual network link using Remote NDIS (RNDIS). This virtualized TCP/IP pipeline allowed Visual Studio’s debugging host to communicate reliably with the target device's operating system.

Core Connectivity (CoreCon) Framework

The actual runtime mechanism responsible for live step-through debugging was the Microsoft Core Connectivity (CoreCon) framework. When a developer initiated a debugging session (F5) targeting a physical device, Visual Studio silently deployed several CoreCon components to the mobile device’s \Windows or \Program Files directory:

  • Conman Client2.exe (Connection Manager Client)
  • CMAccept.exe (Connection Manager Acceptor)
  • TcpConnectionA.dll
  • eDbgTL.dll

These binaries acted as a device-side debug agent. The agent attached to the target process, managed hardware and software execution breakpoints, trapped processor exceptions, and transmitted thread states, call stacks, and variable values back to Visual Studio over the tethered link.

For devices with strict security policies or locked application environments, developers frequently had to manually copy these CoreCon files to the device using a storage card and run CMAccept.exe directly on the hardware to authorize the remote debugging session.

Execution Environments Supported

Using this toolchain, engineers could perform live, line-by-line debugging across two execution runtimes:

  • Native Win32 / C++: Debugged using the native ARM debugger inside Visual Studio, allowing register inspection, memory dumps, and real-time execution flow control across native APIs.
  • .NET Compact Framework (2.0 and 3.5): Debugged via the CLR remote debugging monitor built into the Compact Framework, allowing step-through execution, watch evaluation, and exception tracing in C# and Visual Basic .NET applications.
