  • Easy access to all ETM modes, triggers and filtering
  • Only one connection to target–both JTAG and trace are taken from a high-density, 20-pin Cortex header

Available product versions

JTAGjet-Trace for Cortex-M

Supports Cortex-M cores equipped with ETM trace logic

JTAGjet-Trace for Arm Supports all Arm7, Arm9, Arm11, Cortex-M, Cortex-A8/A9, and Cortex-R4 cores equipped with ETM trace logic

JTAGjet C2000 emulator

Note: This emulator is not compatible with IAR Embedded Workbench

Hardware Features

  • Supports TI TMS320C24xx and F28xx DSPs
  • USB 2.0 high-speed port (480 Mbps) provides faster downloads
  • Includes fully isolated JTAG adapter (ADA_ISO_TI14_E)
  • Supports all on-chip breakpoints and RTDX.
  • Powered by USB port – no external power adapters needed
  • LEDs provide status of target power, JTAG activity, PC host activity and emulator power

Software Features

  • Supports Code Composer Studio v. 3.3 to v. 6.10.0 (Newer CCS versions are not supported)
  • Includes Flash Programmer utility (does not need CCS)
  • Change JTAG clock even when the CCS is running
  • Detects and graphically shows all devices on the JTAG chain
  • Graphically monitors all pins on the JTAG header
  • Windows 7, Vista and XP compatible


Flasher-C2000 is a software utility that enables JTAGjet-C2000 to program the on-chip Flash memory of the Texas Instruments F2000 DSP devices. This utility works stand-alone and does not require the Code Composer Studio to be installed. The Flasher SW can be used in GUI mode for engineering purposes, or in batch mode for production purposes and supports both the TI COFF files and Intel HEX files for programming.
