The GUI displays a README.md prompt each time the GUI is launched. The prompt can be disabled for subsequent sessions by selecting the I checkbox at the bottom of the window. The README.md information is always available in the Help tab at the top of the GUI.

The GUI automatically attempts to connect to the flashed LaunchPad, with the connection status displayed in the bottom left hand corner of the GUI window. Once connected to the LaunchPad, the GUI attempts to read the register information of the PMIC populated in the socket. If the PMIC appears unresponsive, verify the serial port connection and confirm that all relevant shunts are populated according to Figure 2-2. If all shunts are populated properly, pressing the RST button on the LaunchPad (S3) below the socketed board can often recover USB communication.
