EVAL-ADIN2111EVB Evaluation board
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.

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:
$ 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 Hello World application.
# From the root of the zephyr repository
west build -b adi_eval_adin2111ebz samples/hello_world
west flash
You should see the following message on the console:
Hello World! adi_eval_adin2111ebz
Debugging
You can debug an application in the usual way. Here is an example for the Hello World application.
# From the root of the zephyr repository
west build -b adi_eval_adin2111ebz samples/hello_world
