LynuxWorks rolled out news versions of two of its embedded system development tools at the Embedded Systems Conference in San Francisco today: version of 2.0 SpyKer, an embedded system trace tool; and version 5.0 of VisualLynux, a cross development tool which now enables BlueCat Linux and LynxOS RTOS application development using Microsft's new .NET products including Visual Studio .NET and Visual C++ .NET.

SpyKer is described as a dynamically instrumented system trace analyzer that enables developers to display and interact with data concerning their embedded Linux or LynxOS RTOS based applications, thus performing the functions of a "software logic analyzer". SpyKer's dynamic kernel instrumentation capability eliminates the annoyance and configuration management associated with switching to a specially instrumented kernel for debug and trace purposes. Version 2.0 includes new features that enhance visualization capabilities, provide greater system execution visibility, and allow developers to better analyze and understand the causes of system crashes, the company said. Version 2.0 provides more options for save, state, zoom out display, current priority display, and display filtering, allowing for greater and more refined visibility into the system; it also adds histogram capability, allowing both the length of time spent in interrupt context and the timing information between two event points to be displayed as a histogram of timings over the entire trace. Another new feature is the addition of library code instrumentation, which provides detailed information on system operation with minimal intrusion into system performance. Additionally, the ability to display a trace post mortem is included (requires addition of a separate memory board).

According to LynuxWorks, VisualLynux installs on top of an existing installation of Microsoft Visual Studio, and provides the necessary commands and tools for developing applications targeted to LynxOS RTOS and BlueCat embedded Linux based systems. Version 5.0 adds support for Microsft's new .NET products, including Visual Studio .NET and Visual C++ .NET. The new version of VisualLynux also adds Wizard Dialog Boxes which are used to capture LynxOS and BlueCat Linux specific configuration information, as well as Application Wizards that create application skeleton code utilizing many POSIX API features. Remote debugging and target download/viewing tools are also included to allow the Visual Studio environment to function as a true cross-development IDE.
