ADI EVAL-ADIN1110EVB Evaluation board
#####################################

Overview
********

The EVAL-ADIN1110EBZ is a flexible platform enabling quick evaluation of the ADIN1110, robust,
low power 10BASE-T1L MAC-PHY. It provides 10Mbit per second Single Pair Ethernet (SPE) connections
with devices across 1.7km of cable.

The evaluation board offers two modes of operation for maximum flexibility. Connected to a PC
via USB port, the full set of ADIN1110 register settings and features such as link quality
monitoring and diagnostics can be accessed over the USB using serial command interface.
The board also provides an Arduino interface.

Alternatively, the board can operate in stand-alone mode where it is configured by setting hardware
configuration links and switches. On-board LEDs provide status indication.

The SPI interface provides configuration and data access to the ADIN1110.

A small prototyping area and test points are provided for experimentation with alternative cable
connection topologies including isolation transformers and/or power coupling inductors.

.. important::

   S201 DIP switches are shipped in Open Alliance SPI mode. The current Zephyr
   default board configuration is set to work as "Generic SPI, CRC enabled",
   so the S201 DIP switches must be set as ``SPI_CFG0 OFF`` and ``SPI_CFG1 ON``.
   An inconsistent S201 DIP switches configuration will halt the boot.

Connections and IOs
===================

ADI ADIN1110EBZ evaluation board has 7 GPIO controllers (from A to G). These controllers are
responsible for pin muxing, input/output, pull-up, etc.

For mode details please refer to `EVAL-ADIN1110EBZ User Guide <https://wiki.analog.com/resources/eval/user-guides/eval-adin1110ebz-user-guide>`_.

Default Zephyr Peripheral Mapping:

to a FT232, so available through Micro USB connector. Default settings are 115200 8N1.


Programming and Debugging
*************************

Flashing
========

EVAL-ADIN1110EBZ includes an ST-LINK/V2-1 JTAG/SWD 10 or 20 pin connector. This interface is
supported by the openocd version included in Zephyr SDK.

Flashing an application to  Discovery kit
-----------------------------------------

Connect the EVAL-ADIN1110EBZ to your host computer using the USB port, then run a serial host
program to connect with your ADI board. For example:

.. code-block:: console

   $ minicom -D /dev/serial/by-id/usb-ADI_EVAL-ADIN1110EBZ_AVAS_XXXXXX-if00-port0

where XXXXXX is the serial number of the connected device.
Then, build and flash in the usual way. Here is an example for the :ref:`hello_world` application.

.. zephyr-app-commands::
   :zephyr-app: samples/hello_world
   :board: adi_eval_adin1110ebz
   :goals: build flash

You should see the following message on the console:

.. code-block:: console

   Hello World! adi_eval_adin1110ebz

Debugging
=========

You can debug an application in the usual way.  Here is an example for the :ref:`hello_world`
application.

.. zephyr-app-commands::
   :zephyr-app: samples/hello_world
   :board: adi_eval_adin1110ebz
   :maybe-skip-config:
   :goals: debug
