Security components
|
|
===================
|
|
|
|
- Implementation Defined Attribution Unit (`IDAU`_). 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
|
|
*************************
|
|
|
|
``nrf9151dk/nrf9151`` supports the Armv8m Security Extension, and by default boots
|
|
in the Secure state.
|
|
|
|
Building Secure/Non-Secure Zephyr applications with Arm |reg| TrustZone |reg|
|
|
=============================================================================
|
|
|
|
The process requires the following steps:
|
|
|
|
1. Build the Secure Zephyr application using ``-DBOARD=nrf9151dk/nrf9151`` and
|
|
``CONFIG_TRUSTED_EXECUTION_SECURE=y`` in the application project configuration file.
|
|
2. Build the Non-Secure Zephyr application using ``-DBOARD=nrf9151dk/nrf9151/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=nrf9151dk/nrf9151``.
|
|
|
|
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 :zephyr:code-sample:`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 nRF9151 DK
|
|
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: nrf9151dk/nrf9151
|
|
:goals: build flash
|
|
|
|
Debugging
|
|
=========
|
|
|
|
Refer to the :ref:`nordic_segger` page to learn about debugging Nordic boards with a
|
|
Segger IC.
|
|
|
|
|
|
Testing the LEDs and buttons in the nRF9151 DK
|
|
**********************************************
|
|
|
|
There are 2 samples that allow you to test that the buttons (switches) and LEDs on
|
|
the board are working properly with Zephyr:
|
|
|
|
* :zephyr:code-sample:`blinky`
|
|
* :zephyr:code-sample:`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/nordic/nrf9151dk/nrf9151dk_nrf9151_common.dtsi`.
