Browse source 
Add support for u-blox EVK-NINA-B4, which uses the nRF52833

This board is similar to the nrf52833dk_nrf52833, though it
uses a u-blox NINA-B40x openCPU module with DC-DC support
included.
Simplified pwm LED aliases
Corrected LED assignments for red, green, and blue
Addressed review comments (spi & gpio 0 0)

Tested with blinky, button, and Bluetooth peripheral_hr

Connections and IOs
===================
LED
---
* LED0 (red) = P0.13
* LED1 (green) = P1.01
* LED2 (blue) = P1.00
Push buttons
------------
* BUTTON1 = SW1 = P1.01 (Shared with green LED)
* BUTTON2 = SW2 = P0.02
General information on module pin numbering
-------------------------------------------
The numbering of the pins on the module and EVK do not follow the GPIO
numbering on the nRF52833 SoC. Please see the `NINA-B40 Data Sheet`_ for
information on how to map NINA-B40 pins to the pin numbering on the
nRF52833 SoC.
The reason for this is the u-blox module family concept where different
modules share the same pinout and can be interchanged, see
`NINA module family Nested design`_.
Programming and Debugging
*************************
Applications for the ``ubx_evkninab4_nrf52833`` board configuration can be
built and flashed in the usual way (see :ref:`build_an_application`
and :ref:`application_run` for more details); however, the standard
debugging targets are not currently available.
Flashing
========
Build and flash applications as usual (see
:ref:`build_an_application` and :ref:`application_run` for more details)
Here is an example for the :ref:`hello_world` application.
Open a terminal program to the USB Serial Port installed when connecting
the board and listen for output.
Settings: 115200, 8N1, no flow control.
Then build and flash the application in the usual way.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: ubx_evknina4_nrf52833
:goals: build flash
Debugging
=========
Refer to the :ref:`nordic_segger` page to learn about debugging boards
containing a Nordic Semiconductor chip with a Segger IC.
Testing the LEDs and buttons in the EVK NINA-B40x
*************************************************
There are 2 samples that allow you to test that the buttons (switches)
and LEDs on the board are working properly with Zephyr:
.. code-block:: console
samples/basic/blinky
samples/basic/button
You can build and flash the examples to make sure Zephyr is running
correctly on your board. The button and LED definitions can be found in
:zephyr_file:`boards/arm/ubx_evkninab4_nrf52833/ubx_evkninab4_nrf52833.dts`.
Note that the buttons on the EVK-NINA-B4 are marked SW1 and SW2, which
are named sw0 and sw1 in the dts file.
Also note that the SW1 button and the green LED are connected on HW level.
Using UART1
***********
The following approach can be used when an application needs to use
more than one UART for connecting peripheral devices:
1. Add device tree overlay file to the main directory of your application:
.. code-block:: console
$ cat ubx_evk_ninab4nrf52833.overlay
&uart1 {
compatible = "nordic,nrf-uarte";
current-speed = <115200>;
status = "okay";
tx-pin = <14>;
rx-pin = <16>;
};
In the overlay file above, pin P0.16 is used for RX and P0.14 is used for TX
2. Use the UART1 as ``device_get_binding("UART_1")``
Overlay file naming
===================
The file has to be named ``<board>.overlay`` and placed in the app main directory to be
picked up automatically by the device tree compiler.
Selecting the pins
==================
To select the pin numbers for tx-pin and rx-pin:
.. code-block:: console
tx-pin = <pin_no>
Open the data sheet for the NINA-B4 at `NINA-B40 Data Sheet`_, Section 3 'Pin definition'.
In the table 7 select the pins marked 'GPIO_xx'. Note that pins marked as 'Radio sensitive pin'
can only be used in under-10KHz applications. They are not suitable for 115200 speed of UART.
Translate 'Pin' into number for Device tree by using the following formula::
pin_no = b\*32 + a
where ``a`` and ``b`` are from the Pin value in the table (Pb.a).
For example, for P0.1, ``pin_no = 1`` and for P1.0, ``pin_no = 32``.
.. note:
Pins are defined according to the "nRF52" pin number, not the module pad number.
