### Flash the board
The board is flashed using the `adafruit-nrfutil` Python package:
```
$ pip install --user adafruit-nrfutil
```
Example with `hello-world` application:
```
make BOARD=adafruit-clue -C examples/basic/hello-world flash
```
The board is flashed using its on-board
[bootloader](https://github.com/adafruit/Adafruit_nRF52_Bootloader).
More information about how to work with this bootloader can be found in the
@ref boards_common_adafruit-nrf52-bootloader section.

```

```
The `TERM_DELAY` environment variable can be used to add a delay (in second)
before opening the serial terminal. The default value is 2s which should be
enough in most of the situations.

### Flash the board
The board is flashed using its on-board [boot loader](https://github.com/adafruit/Adafruit_nRF52_Bootloader).
Adafruit has a special version of the [nrfutil](https://github.com/adafruit/Adafruit_nRF52_nrfutil) that program needs to
be installed. It can turn the binary into a suitable zip file and send it to the DFU
bootloader.
The process is automated in the usual `make flash` target.
If RIOT is already running on the board, it will automatically reset the CPU and enter
the bootloader.
If some other firmware is running or RIOT crashed, you need to enter the bootloader
manually by double tapping the board's reset button.
Readiness of the bootloader is indicated by LD1 pulsing in blue.
Important to note that Adafruit's nrfutil is not compatible with Nordic's nrfutil.
#### nrfutil installation
On systems with Python 3, a recent version of pip is required to install all dependencies;
you may need to run `pip3 install --upgrade pip3` before being able to run `pip3 install adafruit-nrfutil` successfully.
The board is flashed using its on-board
[bootloader](https://github.com/adafruit/Adafruit_nRF52_Bootloader).
