Overview
|
|
********
|
|
|
|
Raytac MDBT53-DB-40 demo board is a development board based on the Raytac MDBT53-1M module,
|
|
using Nordic Semiconductor nRF5340 ARM Cortex-M33 SoC. Its design concept is to connect all
|
|
of the module's pins to 2.54mm pin headers. It is convenient for developers to verify whether
|
|
the modules are connected to other peripheral devices or sensors as a tool for software development.
|
|
|
|
The nRF5340 inside the MDBT53-1M module is a
|
|
dual-core SoC based on the Arm® Cortex®-M33 architecture, with:
|
|
|
|
* a full-featured Arm Cortex-M33F core with DSP instructions, FPU, and
|
|
Armv8-M Security Extension, running at up to 128 MHz, referred to as
|
|
the **application core**
|
|
* a secondary Arm Cortex-M33 core, with a reduced feature set, running
|
|
at a fixed 64 MHz, referred to as the **network core**.
|
|
|
|
The ``raytac_mdbt53_db_40/nrf5340/cpuapp`` build target provides support for the application
|
|
core on the nRF5340 SoC. The ``raytac_mdbt53_db_40/nrf5340/cpuapp`` build target provides
|
|
support for the network core on the nRF5340 SoC.
|
|
|
|
nRF5340 SoC provides support for the following devices:
|
|
|
|
* :abbr:`ADC (Analog to Digital Converter)`
|
|
* CLOCK
|

Security components
|
|
===================
|
|
|
|
- Implementation Defined Attribution Unit (`IDAU`_) on the application core.
|
|
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
|
|
*************************
|
|
|
|
nRF5340 application core supports the Armv8-M Security Extension.
|
|
Applications built for the ``raytac_mdbt53_db_40/nrf5340/cpuapp`` board by
|
|
default boot in the Secure state.
|
|
|
|
nRF5340 network core does not support the Armv8-M Security Extension.
|
|
nRF5340 IDAU may configure bus accesses by the nRF5340 network core
|
|
to have Secure attribute set; the latter allows to build and run
|
|
Secure only applications on the nRF5340 SoC.
|
|
|
|
Applications for the ``raytac_mdbt53_db_40_nrf5340`` board configuration can be
|
|
built, flashed, and debugged in the usual way. See :ref:`build_an_application` and
|
|
:ref:`application_run` for more details on building and running.
|
|
|
|
.. note::
|
|
Flashing and Debugging Zephyr onto the raytac_mdbt53_db_40_nrf5340 board
|
|
requires an external J-Link programmer. The programmer is attached to the J1
|
|
or J9 SWD connector.
|
|
|
|
|
|
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).
|
|
|
|
.. warning::
|
|
|
|
The nRF5340 has a flash read-back protection feature. When flash read-back
|
|
protection is active, you will need to recover the chip before reflashing.
|
|
If you are flashing with :ref:`west <west-build-flash-debug>`, run
|
|
this command for more details on the related ``--recover`` option:
|
|
|
|
Here is an example for the :ref:`hello_world` application.
|
|
|
|
Use a USB to TTL converter to connect the computer and raytac_mdbt53_db_40_nrf5340
|
|
J10 connector. Then 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 USB to TTL converter
|
|
can be found. For example, under Linux, :code:`/dev/ttyUSB0`.
|
|
|
|
Then build and flash the application in the usual way.
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/hello_world
|
|
:board: raytac_mdbt53_db_40_nrf5340
|
|
:goals: build flash
|
|
|
|
Debugging
|
|
=========
|
|
|
|
The ``raytac_mdbt53_db_40_nrf5340`` board does not have an on-board-J-Link debug IC,
|
|
however, instructions from the :ref:`nordic_segger` page also apply to this board.
|
|
Use the Debug out connector of nRF52x DK to connect to the J1 connector, and use SEGGER
|
|
J-Link OB IF to debug.
|
|
|
|
Refer to the :ref:`nordic_segger` page to learn about debugging Nordic
|
|
boards with a Segger IC.
