@brief Support for the nRF52840-MDK
### General information
The Makerdiary [nRF52840-MDK](https://github.com/makerdiary/nrf52840-mdk) board
is an opensource, micro development kit using the nRF52840 SoC.
This board provides 802.15.4 and BLE connectivity.
### Pinout
<img src="https://github.com/makerdiary/nrf52840-mdk/blob/master/docs/images/nrf52840-mdk-pinout.jpg"
alt="pinout" style="height:800px;"/>
### Flash the board
By default, the board is flashed with PyOCD programmer via a DAPLink.
PyOCD can be installed using Python package manager:
```
pip install pyocd --user -U
```
To flash the board `BOARD=nrf52840-mdk` with the `make` command.<br/>
Example with `hello-world` application:
```
make BOARD=nrf52840-mdk -C examples/hello-world flash
```
OpenOCD can also be used. For the moment, the latest stable version of OpenOCD
(0.10) doesn't contain any support for nrf52 but versions built against the
actual development version can be used.
To flash the board with OpenOCD, use the `PROGRAMMER` variable:
```
PROGRAMMER=openocd make BOARD=nrf52840-mdk -C examples/hello-world flash
```
### Accessing STDIO via UART
The STDIO is directly accessible via the USB port. On a Linux host, it's
generally mapped to `/dev/ttyACM0`.
Use the `term` target to connect to the board serial port<br/>
```
make BOARD=nrf52840-mdk -C examples/hello-world term
```
