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

    3. If the hardware still does not connect, check to make sure the correct GUI/EVM combination is being used.
      1. If the correct GUI/EVM combination is being used, the firmware of the SCB needs to be reprogrammed as described in Firmware Debug.
      2. Many connectivity issues can be addressed by performing one of the following actions:
        1. Long-press the reset (RST) button on the EVM with the EVM and SCB connected to each other.
          • Refreshing the GUI can also sometimes help.
        2. Connect the EVM to a different USB port.
          • Avoid using long cables and USB hubs.
          • If a desktop PC is being used, try a USB port on the back.
