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 text Hardware Connected should be visible near the bottom left corner of the GUI.
Figure 4-6 Hardware Connected
A green indicator with the device type and the text DEVICE CONNECTED should also be visible near the top left of the GUI.
Figure 4-7 Device Connected
If the text Hardware Connected and DEVICE CONNECTED do not show in the GUI, long-press the RESET button on the EVM to try again.
If that option does not work, check different hardware COM ports under Options > Serial Port.

If the hardware still does not connect, make sure you are using the correct GUI/EVM combination.
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.
Many connectivity issues can be addressed by doing one of the following:
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.
Connect the EVM to a different USB port.
Avoid using long cables and USB hubs.
If you are using a desktop PC, try a USB port on the back.
