Tiva™ C Series TM4C123G LaunchPad

The TM4C123GXL LaunchPad Board ICDI USB port is a composite USB port and consists of three connections:

  • Stellaris ICDI JTAG/SWD Interface – debugger connection
  • Stellaris ICDI DFU Device – firmware update connection
  • Stellaris Virtual Serial Port – a serial data connection

Using the included USB cable,

  • Connect your evaluation board’s USB emulation connector (labeled DEBUG) to a free USB port on your computer.
  • The USB port on a PC can supply up to 500 mA for each connected device, which is enough for the evaluation board.
  • If you’re using a USB hub to connect the board, be sure it’s a powered hub.


  • Switch the POWER SELECT switch to the right for DEBUG mode.
  • Connect the USB-A cable plug to an available port on the PC and the Micro-B plug to the Debug USB port on the Board.
  • Verify that the POWER LED D4 on the board is lit.
  • The drivers should download and install themselves.
