Overview |
|
******** |
|
|
|
The EVAL-ADIN2111EBZ is a flexible platform enabling quick evaluation of the ADIN2111, robust, |
|
low power 10BASE-T1L 2-Port Ethernet switch. The evaluation board provides 2 10BASE-T1L channels |
|
with 10Mbit per second Single Pair Ethernet (SPE) connections reaching up to 1.7km of link distance. |
|
|
|
The ADIN2111 internal switch can be configured in store and forward mode between the two 10BASE-T1L |
|
channels and the SPI host. Cut through mode is also available between Port 1 and Port 2 and can |
|
be used without the need of the SPI host (unmanaged configuration). |
|
|
|
The evaluation board offers two modes of operation for maximum flexibility: Connected to a PC |
|
via USB port, the full set of ADIN2111 register settings and features such as link quality |
|
monitoring and diagnostics can be accessed over the USB using the serial command interface |
|
implemented in the evaluation firmware. |
|
|
|
Alternatively, the board can operate in cut-through mode between Port 1 and Port 2 (unmanaged |
|
configuration without firmware) where the EVAL-ADIN2111EBZ acts as a network switch forwarding |
|
packets between the 2x 10BASE-T1L ports. The 2x links are configured by setting the ADIN2111 |
|
hardware configuration pins jumper and switches. The 2x On-board Activity LEDs provide Link |
|
activity status indication for each port. |
|
|
|
Custom firmware can also be developed and the ADIN2111 driver support package includes simple |
|
project examples to start a custom implementation. |
|
|
|
The SPI interface provides access to the management registers required for the switch configuration, |
|
the 2 PHYs configuration and data exchange between SPI host and ports. |
|
|
|
.. important:: |
|
|
|
S1 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 S1 DIP switches must be set as ``SPI_CFG0 OFF and SPI_CFG1 OFF``. |
|
An inconsistent S1 DIP switches configuration will halt the boot. |

Connections and IOs |
|
=================== |
|
|
|
ADI ADIN2111EBZ evaluation board has 7 GPIO controllers (from A to G). |
|
These controllers are responsible for pin muxing, input/output, pull-up, etc. |
|
|
|

Default Zephyr Peripheral Mapping: |
|
---------------------------------- |
|
|
|
- UART_1 TX/RX : PA9/PA10 (UART to FT232, console) |
|
- SPI1 SCK/MISO/MOSI : PA5/PA6/PA7 (SPI to external nor flash IS25LP128) |
|
- SPI2 SCK/MISO/MOSI : PB13/PB14/PB15 (SPI to external ADIN2111) |
|
- LED1 : POWER (Green LED) |
|
- UC_LED1 : PB6 (Blue LED) |
|
- MOD LED1 : PE2 (SR LED) |
|
- MOD LED2 : PE6 (BG LED) |
|
- NET LED1 : PB10 (SR LED) |
|
- NET LED2 : PB11 (BG LED) |
|
|
|
|
|
System Clock |
|
------------ |
|
|
|
EVAL-ADIN2111EBZ System Clock could be driven by an internal or external oscillator, as well as the |
|
main PLL clock. By default the System clock is driven by the PLL clock at 80MHz, driven by the |
|
16MHz high speed internal oscillator. |
|
|
|
Serial Port |
|
----------- |
|
|
|
EVAL-ADIN2111EBZ has 1 U(S)ART. The Zephyr console output is assigned to UART1 that is connected |
|
to a FT232, available through Micro USB connector. Default settings are 115200 8N1. |
|
Same UART1 TX and RX cmos signals are available before the FT232, at P9 connector. |

Programming and Debugging |

|
|
|
Flashing |
|
======== |
|
|
|
EVAL-ADIN2111EBZ 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-ADIN2111EBZ 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-ADIN2111EBZ_XXXXXX-12-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 :zephyr:code-sample:`hello_world` application. |
|
|
|
.. zephyr-app-commands:: |
|
:zephyr-app: samples/hello_world |
|
:board: adi_eval_adin2111ebz |
|
:goals: build flash |
|
|
|
You should see the following message on the console: |
|
|
|
.. code-block:: console |
|
|
|
Hello World! adi_eval_adin2111ebz |
|
|
|
Debugging |
|
========= |
|
|
|
You can debug an application in the usual way. Here is an example for the :zephyr:code-sample:`hello_world` |
|
application. |
|
|
|
.. zephyr-app-commands:: |
|
:zephyr-app: samples/hello_world |
|
:board: adi_eval_adin2111ebz |
|
