Overview
7+
********
8+
9+
This demo board features a Microchip CEC1702 cryptographic
10+
embedded controlled based on an ARM Cortex-M4.
11+
12+
Highlights of the board:
13+
14+
- CEC1702 32-bit ARM® Cortex®-M4F Controller with Integrated Crypto
15+
- Compact, high-contrast, serial graphic LCD Display Module with back-light
16+
- 2x4 matrix of push buttons inputs
17+
- USB-UART Converter as debug interface
18+
- Potentiometer to ADC channel
19+
- Serial Quad I/O (SQI) flash
20+
- OTP programmable in CEC1702
21+
- Two expansion headers compatible with MikroElektronika mikroBUS™ Expansion interface
22+
23+
More information can be found on the `SecureIoT1702 website`_ and
24+
`CEC1702 website`_, and SoC programming information is available
25+
in the `CEC1702 datasheet`_.
26+
27+
Supported Features
28+
==================
29+
30+
The following devices are supported:
31+
32+
- Nested Vectored Interrupt Controller (NVIC)
33+
- System Tick System Clock (SYSTICK)
34+
- Serial Ports (NS16550)
35+
36+
37+
Connections and IOs
38+
===================
39+
40+
Please refer to the `SecureIoT1702 schematics`_ for the pin routings.
41+
Additional devices can be connected via mikroBUS expansion interface.
42+
43+
Programming and Debugging
44+
*************************
45+
46+
This board comes with a 10-pin Cortext Debug port and a separate SPI
47+
flash programming header.
48+
49+
Applications for the ``secureiot1702`` board configuration can be
50+
built the usual way (see :ref:`build_an_application` for more details) which
51+
is then programmed directly to the external SPI flash chip.
52+
53+
Flashing
54+
========
55+
56+
# Add extra configuration :code:`CONFIG_BOOT_DELAY=4000` in :code:`prj.conf`.
57+
This is needed for the host USB drivers to be ready to see the boot messages.
58+
Build :ref:`hello_world` application. The build will result
59+
in :code:`zephyr_spi_image.bin`.
60+
61+
.. zephyr-app-commands::
62+
:zephyr-app: samples/hello_world
63+
:board: secureiot1702
64+
:goals: build
65+
66+
#. Connect your SPI programmer to SecureIoT1702 connector X12 in order to flash.
67+
Then proceed to flash using flashrom v1.1 or a similar tool for flashing
68+
SPI chip with :code:`zephyr_spi_image.bin`.
69+
70+
.. code-block:: console
71+
72+
$ flashrom -w zephyr_spi_image.bin
73+
74+
#. Run your favorite terminal program to listen for output. Under Linux the
75+
terminal should be :code:`/dev/ttyUSB0`. For example:
76+
77+
.. code-block:: console
78+
79+
$ minicom -D /dev/ttyUSB0 -o -b 115200
80+
81+
The -o option tells minicom not to send the modem initialization
82+
string. Connection should be configured as follows:
83+
84+
- Speed: 115200
85+
- Data: 8 bits
86+
- Parity: None
87+
- Stop bits: 1
88+
89+
#. Connect the SecureIoT1702 to your host computer using the USB connector.
90+
91+
You should see "Hello World! secureiot1702" in your terminal.
92+
93+
Debugging
94+
=========
95+
96+
You can debug an application in the usual way. Here is an example for the
97+
:ref:`hello_world` application.
98+
99+
.. zephyr-app-commands::
100+
:zephyr-app: samples/hello_world
101+
:board: mec15xxevb_assy6853
