Connecting the board


Tiva™ C Series TM4C123G LaunchPad

The TM4C123GXL LaunchPad Board ICDI USB port (marked DEBUG and shown in the picture below) 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 the USB emulation connector on your evaluation board (marked DEBUG) to a free USB port on your PC. A PC’s USB port is capable of sourcing up to 500 mA for each attached device, which is sufficient for the evaluation board. If connecting the board through a USB hub, it must be a powered hub. The drivers should install automatically.


Make sure that the power switch in the upper left hand corner of your board is in the right-hand DEBUG position as shown:


  • 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.
