This will set your power shield to launch the USB DFU bootloader, which is the interface we will use to upgrade the firmware.
Step 3. Connect the power shield using a USB cable to your host device and launch the STM32CubeProgrammer application.
You can find, download, and install the latest version of STM32CubeProgrammer on st.comStep 4. We will be using the USB DFU interface to update the power shield’s firmware version. Establish a connection between STM32CubeProgrammer and the power shield by changing the interface via the drop-down menu to USB and clicking on the “connect” icon.
Step 5. Click on the open file tab.
Step 6. Locate and select the power shield's firmware. This is the '.hex' file included within the .zip file downloaded earlier in step 1.
Step 7. Click on the 'download' icon, and STM32CubeProgrammer should state that the download of the file to the target has been completed.
Congratulations! Your power shield should now be upgraded with the latest firmware version. To verify this new firmware version, disconnect your power shield from STM32CubeProgrammer and power cycle the board.
