System Clock
============

nRF52 has two external oscillators. The frequency of the slow clock is
32.768 kHz. The frequency of the main clock is 32 MHz.

Serial Port
-----------

96Boards Nitrogen has one UART, which is used as Zephyr console.
Default settings is 115200 8N1.

I2C
---

96Boards Nitrogen has one I2C. The default I2C mapping for Zephyr is:

- I2C0_SCL : P0.22
- I2C0_SDA : P0.20

SPI
---

96Boards Nitrogen has one SPI. The default SPI mapping for Zephyr is:

- SPI0_NSS  : P0.24
- SPI0_SCK  : P0.26
- SPI0_MISO : P0.25
- SPI0_MOSI : P0.23

Flashing Zephyr onto 96Boards Nitrogen
**************************************

The 96Boards Nitrogen board can be flashed via the `CMSIS DAP`_ interface,
which is provided by the micro USB interface to the LPC11U35 chip.

Using the CMSIS-DAP interface, the board can be flashed via the USB storage
interface (drag-and-drop) and also via `pyOCD`_.

To use ``pyOCD``, install the :ref:`pyocd-debug-host-tools` and make sure they
are in your search path.

Common Errors
=============

No connected boards
-------------------

If you don't use sudo when invoking pyocd-flashtool, you might get any of the
following errors:

.. code-block:: console

   No available boards are connected

.. code-block:: console

   No connected boards

.. code-block:: console

   Error: There is no board connected.

To fix the permission issue, simply add the following udev rule for the
NXP LPC1768 interface:

.. code-block:: console

   $ echo 'ATTR{idProduct}=="0204", ATTR{idVendor}=="0d28", MODE="0666", GROUP="plugdev"' > /etc/udev/rules.d/50-cmsis-dap.rules

Finally, unplug and plug the board again.

ValueError: The device has no langid
------------------------------------

As described by `pyOCD issue 259`_, you might get the
:code:`ValueError: The device has no langid` error when not running
pyOCD as root (e.g. sudo).

To fix the above error, add the udev rule shown in the previous section
and install a more recent version of pyOCD.

Flashing an Application to 96Boards Nitrogen
============================================

Here is an example for the :ref:`hello_world` application. This
requires installing the :ref:`pyocd-debug-host-tools`.

.. zephyr-app-commands::
   :zephyr-app: samples/hello_world
   :board: 96b_nitrogen
   :goals: build flash

Run your favorite terminal program to listen for output.

.. code-block:: console

   $ minicom -D <tty_device> -b 115200

Replace :code:`<tty_device>` with the port where the board 96Boards Nitrogen
can be found. For example, under Linux, :code:`/dev/ttyACM0`.
The ``-b`` option sets baud rate ignoring the value from config.

Press the Reset button and you should see the following message in your
terminal:

.. code-block:: console

   Hello World! arm

Debugging with GDB
==================

You can debug an application in the usual way.  Here is an example for the
:ref:`hello_world` application. This also requires pyOCD.

System clock

nRF52에는 external oscillator가 두 개 있습니다. slow clock은 32.768 kHz, main clock은 32 MHz입니다.

Serial port

Nitrogen에는 Zephyr console로 사용하는 UART가 하나 있으며 기본 설정은 115200 8N1입니다.

I2C

I2C 하나의 기본 mapping은 I2C0_SCL: P0.22, I2C0_SDA: P0.20입니다.

SPI

SPI 하나의 기본 mapping은 다음과 같습니다.

SPI0_NSS: P0.24
SPI0_SCK: P0.26
SPI0_MISO: P0.25
SPI0_MOSI: P0.23

Nitrogen에 Zephyr flashing

micro-USB를 통해 LPC11U35가 제공하는 CMSIS-DAP interface로 flash할 수 있습니다. USB storage에 drag-and-drop하거나 pyOCD를 사용할 수 있습니다. pyOCD를 쓰려면 pyOCD Debug Host Tools를 설치하고 실행 파일이 search path에 있어야 합니다.

일반 오류: 연결된 board 없음

pyocd-flashtool을 sudo 없이 실행하면 다음 오류 중 하나가 나타날 수 있습니다.

No available boards are connected
No connected boards
Error: There is no board connected.

권한 문제를 해결하려면 NXP LPC1768 interface용 다음 udev rule을 추가합니다.

$ echo 'ATTR{idProduct}=="0204", ATTR{idVendor}=="0d28", MODE="0666", GROUP="plugdev"' > /etc/udev/rules.d/50-cmsis-dap.rules

그 뒤 board의 USB를 뽑았다 다시 연결합니다.

`ValueError: The device has no langid`

pyOCD issue 259에 설명된 것처럼 pyOCD를 root 권한으로 실행하지 않으면 이 오류가 날 수 있습니다. 앞 절의 udev rule을 추가하고 더 최신 pyOCD를 설치합니다.

애플리케이션 flash

다음 hello_world 예에는 pyOCD Debug Host Tools가 필요합니다.

# Zephyr 저장소 루트에서
west build -b 96b_nitrogen samples/hello_world
west flash

원하는 terminal program으로 출력을 수신합니다.

$ minicom -D <tty_device> -b 115200

<tty_device>를 Nitrogen이 연결된 port로 바꿉니다. Linux에서는 예를 들어 /dev/ttyACM0입니다. -b option은 설정값과 무관하게 baud rate를 지정합니다. Reset button을 누르면 다음 메시지가 보여야 합니다.

Hello World! arm

GDB debugging

일반적인 방식으로 debug할 수 있으며 다음 예도 pyOCD가 필요합니다.

# Zephyr 저장소 루트에서
west build -b 96b_nitrogen samples/hello_world
west debug
