Overview
4+
********
5+
6+
.. note::
7+
You can find more information about the nRF7120 SoC on the `nRF7120 website`_.
8+
For the nRF7120 technical documentation and other resources (such as
9+
SoC Datasheet), see the `nRF7120 documentation`_ page.
10+
11+
The nRF7120 Development Kit hardware provides support for the Nordic Semiconductor
12+
nRF7120 Arm Cortex-M33 CPU and the following devices:
13+
14+
* :abbr:`SAADC (Successive Approximation Analog to Digital Converter)`
15+
* CLOCK
16+
* :abbr:`GPIO (General Purpose Input Output)`
17+
* :abbr:`TWIM (I2C-compatible two-wire interface master with EasyDMA)`
18+
* MEMCONF
19+
* :abbr:`MPU (Memory Protection Unit)`
20+
* MRAM
21+
* MSPI
22+
* :abbr:`NVIC (Nested Vectored Interrupt Controller)`
23+
* :abbr:`PWM (Pulse Width Modulation)`
24+
* :abbr:`GRTC (Global real-time counter)`
25+
* Segger RTT (RTT Console)
26+
* :abbr:`SPI (Serial Peripheral Interface)`
27+
* :abbr:`UARTE (Universal asynchronous receiver-transmitter)`
28+
* :abbr:`WDT (Watchdog Timer)`
29+
30+
Hardware
31+
********
32+
33+
nRF7120 DK has two crystal oscillators:
34+
35+
* High-frequency 62 MHz crystal oscillator (HFXO)
36+
* Low-frequency 32.768 kHz crystal oscillator (LFXO)
37+
38+
The crystal oscillators can be configured to use either
39+
internal or external capacitors.

Programming and Debugging
47+
*************************
48+
49+
.. zephyr:board-supported-runners::
50+
51+
Applications for the ``nrf7120dk/nrf7120/cpuapp`` board target can be
52+
built, flashed, and debugged in the usual way. See
53+
:ref:`build_an_application` and :ref:`application_run` for more details on
54+
building and running.
55+
56+
Applications for the ``nrf7120dk/nrf7120/cpuflpr`` board target need
57+
to be built using sysbuild to include the ``vpr_launcher`` image for the application core.
58+
59+
Enter the following command to compile ``hello_world`` for the FLPR core:
60+
61+
.. code-block:: console
62+
63+
west build -p -b nrf7120dk/nrf7120/cpuflpr --sysbuild
64+
65+
66+
Flashing
67+
========
68+
69+
As an example, this section shows how to build and flash the :zephyr:code-sample:`hello_world`
70+
application.
71+
72+
.. warning::
73+
74+
When programming the device, you might get an error similar to the following message::
75+
76+
ERROR: The operation attempted is unavailable due to readback protection in
77+
ERROR: your device. Please use --recover to unlock the device.
78+
79+
This error occurs when readback protection is enabled.
80+
To disable the readback protection, you must *recover* your device.
81+
82+
Enter the following command to recover the core::
83+
84+
west flash --recover
85+
86+
The ``--recover`` command erases the flash memory and then writes a small binary into
87+
the recovered flash memory.
88+
This binary prevents the readback protection from enabling itself again after a pin
89+
reset or power cycle.
90+
91+
Follow the instructions in the :ref:`nordic_segger` page to install
92+
and configure all the necessary software. Further information can be
93+
found in :ref:`nordic_segger_flashing`.
94+
95+
To build and program the sample to the nRF7120 DK, complete the following steps:
96+
97+
First, connect the nRF7120 DK to you computer using the IMCU USB port on the DK.
98+
Next, build the sample by running the following command:
99+
100+
.. zephyr-app-commands::
101+
:zephyr-app: samples/hello_world
102+
:board: nrf7120dk/nrf7120/cpuapp
103+
:goals: build flash
104+
105+
Testing the LEDs and buttons in the nRF7120 DK
106+
************************************************
107+
108+
Test the nRF7120 DK with a :zephyr:code-sample:`blinky` sample.
