#################
Overview
********
The nRF9160 innblue22 is a cellular IoT sensor development board, which
is based on the nRF9160 SiP, and features NB-IoT and LTE-M connectivity.

Supported Features
==================
The nrf9160_innblue22 board configuration supports the following
hardware (as of nRF9160) features:
+-----------+------------+----------------------+
| Interface | Controller | Driver/Component |
+-----------+------------+----------------------+
| CLOCK | on-chip | clock_control |
+-----------+------------+----------------------+
| FLASH | on-chip | flash |
+-----------+------------+----------------------+
| GPIO | on-chip | gpio |
+-----------+------------+----------------------+
| I2C(M) | on-chip | i2c |
+-----------+------------+----------------------+
| MPU | on-chip | arch/arm |
+-----------+------------+----------------------+
| NVIC | on-chip | arch/arm |
+-----------+------------+----------------------+
| PWM | on-chip | pwm |
+-----------+------------+----------------------+

Connections and IOs
===================
LED
---
* LED1 ( red ) = P0.7
* LED2 (green) = P0.6
* LED3 ( blue) = P0.5
* LED4 ( red ) = P0.4
Push buttons and Switches
-------------------------
* BUTTON1 = P0.31
Security components
===================
- Implementation Defined Attribution Unit. The IDAU is implemented
with the System Protection Unit and is used to define secure and non-secure
memory maps. By default, all of the memory space (Flash, SRAM, and
peripheral address space) is defined to be secure accessible only.
- Secure boot.
Programming and Debugging
*************************
nrf9160_innblue22 supports the Armv8m Security Extension, and by default boots
in the Secure state.
Building Secure/Non-Secure Zephyr applications
==============================================
The process requires the following steps:
1. Build the Secure Zephyr application using ``-DBOARD=nrf9160_innblue22`` and
``CONFIG_TRUSTED_EXECUTION_SECURE=y`` in the the application project configuration file.
2. Build the Non-Secure Zephyr application using ``-DBOARD=nrf9160_innblue22_ns``.
3. Merge the two binaries together.
When building a Secure/Non-Secure application, the Secure application will
have to set the IDAU (SPU) configuration to allow Non-Secure access to all
CPU resources utilized by the Non-Secure application firmware. SPU
configuration shall take place before jumping to the Non-Secure application.
Building a Secure only application
==================================
Build the Zephyr app in the usual way (see :ref:`build_an_application`
and :ref:`application_run`), using ``-DBOARD=nrf9160_innblue22``.
Flashing
========
Follow the instructions in the :ref:`nordic_segger` page to install
and configure all the necessary software. Further information can be
found in :ref:`nordic_segger_flashing`. Then 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.
First, 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 nRF9160 innblue22
can be found. For example, under Linux, :code:`/dev/ttyACM0`.
Then build and flash the application in the usual way.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: nrf9160_innblue22
:goals: build flash
Debugging
=========
Refer to the :ref:`nordic_segger` page to learn about debugging Nordic boards with a
Segger IC.
