Abstract

The Joint Test Action Group (JTAG) protocol is a primary means of communicating with a microcontroller (MCU) during product development, emulation, and application debug. All of Texas Instruments (TI) C2000™ devices support JTAG emulation and the C2000 evaluation products, such as controlCARDs and LaunchPad™ Development Kits, incorporate onboard JTAG Emulation. The this application report provides a brief overview of JTAG implementation and explains the steps used to resolve common JTAG connectivity errors when using Code Composer Studio™ software.

If you are having problems using JTAG to communicate with the C2000™ device, TI strongly recommends that users follow this debug guide before seeking help through a platform such as TI's E2E™ forum. As part of the screening process, TI support personnel asks about your progress with this guide.
