Software: Chameleon Debugger


Chameleon Debugger is designed for a variety of hardware emulation interfaces to target boards (JTAG, BDM, ICE, STAG) on one end, and a communication channel to the host PC on the other. The program provides a consistent user interface to an embedded project at all stages of the development cycle from CPU evaluation to production testing.

Chameleon supports many different CPUs and DSPs in plain or Multi-Core (SoC) targets in a single debugging environment. Regardless of the number of CPUs being debugged, Chameleon offers... more .

JTAGjet in Tandem with Chameleon: Key Benefits


Ideal for homogeneous and heterogeneous Multi-Core and Multi-CPU targets (SoC) with optional support for:


ARM, XScale, Cortex, OMAP, DaVinci, TMS470, TMS570, TMS320, Tricore and C166.

• Remote debugging over TCP/IP networks.
•   Virtual I/O to give the target CPU access to the host PC console and disk files during development.
•   Graphical Virtual I/O devices (VIPER) to targets to speed-up debugging of prototypes.
•   Drag and drop variables and addresses between windows.
•   Trace window with customizable columns, filters and queries (with ETM or ETB options).
•   Time stamping on all trace entries with CPU cycle resolution (with optional ETM module).

Powerful breakpoints, step-into, step-over and step-out at the C, C++ and assembler levels.

•   Variable values pop-up when the mouse moves over the source code.
•   Variables displayed according to their definitions (structures, unions, strings, etc.).
•   Grouping of on-chip registers together according to function for easy access.
•   Command mode facility with macros (scripts) for automated debug and testing.
•   Real-time logging to outside applications for graphing or post-processing.
• Made in USA.
