3.2.1.3.2 GUI to EVM Connection

To connect the GUI to the EVM, follow these steps:

  1. Set up and launch the GUI as described in Initial Setup

    1. Make sure to connect the EVM to the SCB before powering on

  2. Close the README.md file page to initiate a connection between the EVM and the GUI. If successful, the Hardware Connected message should be visible near the bottom-left corner of the GUI

    1. A green indicator with the device type and the text DEVICE CONNECTED should also be visible near the top-left corner of the GUI

    2. If Hardware Connected and DEVICE CONNECTED do not show in the GUI, long-press the RESET button on the EVM to try again.
      1. If the long-press reset does not work, check different hardware COM ports under Options ➞ Serial Port, as shown in Figure 3-8.

    3. If the hardware still does not connect, make sure you are using the correct GUI and EVM combination.
      1. If you are using the correct GUI and EVM combination, you may need to reprogram the firmware of the SCB described in Firmware Debug.
      2. Many connectivity issues can be addressed by doing one of the following:
        1. Long-press the RESET button on the EVM with the EVM and SCB connected to each other.
          • Refreshing the GUI may also help
        2. Connect the EVM to a different USB port
          • Avoid using long cables and USB hubs
          • If using a desktop PC, try a USB port on the back
