A bootloader is a small application that starts when an Arduino board gets powered. Official Arduino boards come pre-flashed with a bootloader, but to guarantee the best performance and stability it needs to be updated with the latest firmware releases.
Supported boards
- Nicla Vision
Before you begin
Install the latest version of “Arduino Mbed OS Nicla Boards” in Arduino IDE.
Instructions
-
Connect your Nicla Vision to your computer and select it in Arduino IDE.
-
Go to File > Examples > STM32H747_System and open the STM32H747_manageBootloader sketch.
-
Upload the sketch. -
Open the Serial Monitor with Tools > Serial Monitor.
-
When the sketch starts running on the board it will output some device information to the Serial Monitor, check the Bootloader version to see the version currently installed.

- If the Serial Monitor is empty after uploading the sketch, press the reset button to restart the sketch.
- You may need to scroll down to show new lines in the Serial Monitor.
