You only need to do this one time, and then the correct nina-fw firmware will be on the NINA ESP32 chip, and you can just flash the Arduino Nano33 IoT board using TinyGo.
## Updating Adafruit ESP32 WiFi Boards
Adafruit provides very good instructions for updating their boards that provide a ESP32 WiFi-BLE co-processor. For more information, please see:
