The TI TM4C123G LaunchPad evaluation board does not come with an external debug connector. Therefore, in order to use an external debug probe like the J-Link, at the first, the Tiva C Series TM4C123G LaunchPad board needs to be manually setup:

  • Solder a strip header to DBG (see image below)
  • Connect the debug interface signals manually (e.g. using jumping wires) as described in the table below
