4.2.1.3.2 GUI to EVM Connection

To operate the GUI, follow these steps:

  1. Connect to and launch the GUI as described in Section 4.2.1.3.1.
  2. Check to make sure that the EVM connected to the GUI, then close the README.md file page to initiate the connection. If successful, the Hardware Connected message should be visible near the bottom-left corner of the GUI as in Figure 4-6.

    1. A green indicator with the device type and the text DEVICE CONNECTED should also be visible near the top-left of the GUI window, as shown in Figure 4-7.

    2. If Hardware Connected and DEVICE CONNECTED do not show in the GUI, check the different hardware COM ports under Options >> Serial Port, as shown in Figure 4-8.

    3. If the hardware still does not connect, make sure you are using the correct GUI/EVM combination.
      1. If you are using the correct GUI/EVM combination, you may need to reprogram the firmware of the SCB, as described in Section 4.2.1.2.1.
