10 Updating Firmware

Your EVM includes the ability to update the MCU firmware controlling the DRV884xEVM driver device without any additional hardware. There should be a pop-up every time the GUI Driver Control page is selected after an EVM connection is made and if a new update becomes available as can be seen in EVM Firmware Update Pop-Up.

The user can update the EVM to the latest firmware by simply going to File -> Program Device from either the EVM Home Page or the Driver Control page as shown in Figure 9-2. Successful firmware update will bring up a message window stating "Flash Successful!".
