From the Windows Start menu, go to the Texas Instruments folder and under BOOSTXL-TECDRV start the GUI application. A cloud version of the GUI is also available from dev.ti.com in the software gallery. The communication between the GUI and the LaunchPad should be automatically established. If the hardware does not connect, manually try to make the connection by clicking on the connect icon in the lower left portion of the GUI. If the correct serial COM port cannot be found, the desired port can be selected from the Options drop down menu and selecting Serial Port. When the firmware program is successfully downloaded, the GUI software can now communicate with the LaunchPad.
