3.3.1 Hardware Connection

Open the GUI software and plug the USB cable into the USB port of the computer. The Hardware Connection Status Bar on the left down corner of the GUI illustrates the hardware connection status.

Click the connection button to initiate the software connection to the EVM board through the USB2ANY. The connection status shows the connection result of the GUI and EVM board.

  • Hardware Connected indicates the EVM is connected to the GUI successfully
  • Hardware not Connected indicates the EVM is not connected to the GUI successfully

In case the USB2ANY tool has been used to evaluate other EVMs and updated to other firmware version (such as, 2.8.2.0), the firmware version is required to updated to the mapping version of the LP581x_RUKA GUI. After clicking the connection button, the firmware update window appears as shown in Figure 3-4. Follow the steps to complete the firmware update.
