### Update the bootloader
Before deploying any firmware, make sure you have the updated Arduino Nano 33 BLE bootloader, which relocates the bootloader so the softdevice doesn't overwrite it. Please see:
https://docs.arduino.cc/tutorials/nano-33-ble/getting-started-omv
Before deploying any firmware images, make sure the board is running the
updated Arduino Nano 33 BLE bootloader (which is relocated to the end of
the flash), otherwise the bootloader will be overwritten by the softdevice.
For more information on how to update the bootloader, see the
[Getting Started with OpenMV/MicroPython](https://docs.arduino.cc/tutorials/nano-33-ble/getting-started-omv) tutorial.
### Via Arduino bootloader and BOSSA
Download BOSSA from https://github.com/shumatech/BOSSA/ and double tap reset button to enter the Arduino bootloader
Download the latest BOSSA flash programmer from the
[Arduino BOSSA fork](https://github.com/arduino/BOSSA/releases/latest).
Note this version adds support for nRF devices, and must be used with the
Nano 33 BLE. Double tap the reset button to enter the bootloader, and run
the following command:
```bash
bossac -e -w --offset=0x16000 --port=ttyACM0 -i -d -U -R build-arduino_nano_33_ble_sense-s140/firmware.bin
```
Alternatively, a Linux binary can be found here: https://github.com/openmv/openmv/blob/master/tools/bossac
### Via nrfprog
This board can also be programmed via nrfjprog (with Jlink for example), from MicroPython source repository:
