7 Launching the DRV884x-EVM-GUI Application

Whether using the desktop or web version of the GUI, the user experience and steps covered below is the same. These steps assume the hardware setup steps in the previous section have already been completed.

1. Launch the GUI application using Chrome web browser or from your local desktop installation. Note you’ll have to log-in to the TI Dev Gallery using your myTI log-in credentials prior to launching the app while running from a web browser.
   1. Hyperlink for running app in Chrome: Web GUI
2. Select the desired EVM type from the screen referenced in the Figure 7-1 below

3. After clicking the correct EVM type, the GUI application initiates communications with the EVM. Connection confirmation is displayed as shown below:
   Figure 7-2 Successful EVM Connection
4. If the GUI app connection with the EVM is repeatedly not successful, follow the below listed steps to debug the issue.
   1. Check if the serial communications parameters were properly configured. In the GUI, click on the “Options” menu, and select “Serial Port”. Verify if the port selected matches the MSP Application UART1 enumerated in the Device Manager, Windows system Control Panel. The baud rate must be set to 9600 (recommended). If no MSP COMxx ports were enumerated and displayed in the Windows Device Manager, ensure proper power sequencing was followed. If necessary do a power off and on cycle. If the following Windows Device Manager information is still not visible after the power cycle it points to a hardware connection issue.

   2. It is possible that the EVM has a much older version of the firmware. Perform a firmware update using the procedure described in Updating Firmware.
   3. Check if the MCU_STATUS LED D6 is blinking at approximately 1 Hz. If the STATUS LED is not blinking, perform a firmware reset using the push button S1 with jumper J6 in 1-2 RST position. Attempt to connect the GUI app with the EVM again.
5. At this point, the user may set-up the EVM for device evaluation
   • Driver Control page with configuration and diagnostic options.
   • GUI Home page to re-select the EVM if necessary.

6. The "Driver Control" tab will display the firmware version in the top right corner. When you click on "Help > About" it should display the GUI version, Device Rev ID, and the EVM firmware version.
