IAR J-Trace, JTAG+ Trace for ARM

J-Trace

IAR J-Trace is a small hardware debug trace device for ARM processors; it connects via USB to the PC host running Windows. IAR J-Trace integrates seamlessly into IAR Embedded Workbench and also works as a standard JTAG debugger through a separate JTAG port

 

 

General features

 

 

  • USB-driven JTAG and Trace (38-pin Mictor) interface

  • Supports all ARM7 and ARM9 devices.

  • No power supply required, powered through USB, although external power supply plug is available

  • JTAG speed 12 MHz

  • Auto speed recognition

  • USB-2 full speed (12Mbit/sec)

  • Adaptive clock based on RTCK JTAG signal

  • All signals can be monitored, target voltage can be measured

  • 20-pin standard JTAG connector, 38-pin standard Trace Mictor connector

  • USB, 20-pin flat cable and 38-pin trace cable included

  • Full integration with the C-SPY Debugger; advanced debugging features available from C-SPY.

  • Integration into IAR Embedded Workbench for ARM makes setup and use easy

  • Supported platforms: Windows 2000 and Windows XP

 

Trace features

 

  • Trace supports up to 200 MHz full and 100 MHz half clock rate

  • Trace based on ARM ETM (Embedded Trace Macrocell)

  • Trace support for devices with built-in trace ports

  • 2 Mbyte trace memory buffer

  • Compact housing, fits easily on the desk

  • Silent, fanless design

  • Support for cycle accurate and compressed tracing

  • Supports 4 / 8 / 16 bit trace port at both full and half-rate clocking

  • Trace window synchronizes to source and disassembly window

  • Function trace shows called functions hierarchically
