Connect EK-TM4C123GXL LaunchPad Board to PC

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

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.
