### Update the bootloader
2+
3+
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:
4+
5+
https://docs.arduino.cc/tutorials/nano-33-ble/getting-started-omv
6+
7+
### Via Arduino bootloader and BOSSA
8+
9+
Download BOSSA from https://github.com/shumatech/BOSSA/ and double tap reset button to enter the Arduino bootloader
10+
11+
```bash
12+
bossac -e -w --offset=0x16000 --port=ttyACM0 -i -d -U -R build-arduino_nano_33_ble-s140/firmware.bin
13+
```
14+
15+
Alternatively, a Linux binary can be found here: https://github.com/openmv/openmv/blob/master/tools/bossac
16+
17+
### Via nrfprog
18+
19+
This board can also be programmed via nrfjprog (with Jlink for example), from MicroPython source repository:
20+
21+
```bash
22+
make -j8 BOARD=arduino_nano_33_ble SD=s140 deploy
23+
```
