3.1.3.2 GUI to EVM Connection

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

  1. Setup 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, then the text Hardware Connected is visible near the bottom left corner of the GUI.

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

    2. If Hardware Connected and DEVICE CONNECTED do not show in the GUI, then long-press the RESET button on the EVM to try again.
      1. If that option does not work, then check different hardware COM ports under Options > Serial Port.

    3. If the hardware still does not connect, then make sure the correct GUI and EVM combination is being used.
      1. If the correct GUI and EVM combination is being used, then the user needs to reprogram the firmware of the SCB, as 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 can also sometimes help this.
        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.
