+Overview
+********
+
+W5500-EVB-Pico2 is a microcontroller evaluation board based on the Raspberry
+Pi RP2350A and fully hardwired TCP/IP controller W5500 - and basically works
+the same as Raspberry Pi Pico2 board but with additional Ethernet via W5500.
+The USB bootloader allows the ability to flash without any adapter, in a
+drag-and-drop manner. It is also possible to flash and debug the boards with
+their SWD interface, using an external adapter.
+
+Hardware
+********
+
+- Dual core Arm Cortex-M33 or Hazard3 processor running up to 133MHz
+- 520KB on-chip SRAM
+- 16MB on-board QSPI flash with XIP capabilities
+- 26 GPIO pins
+- 3 Analog inputs
+- 2 UART peripherals
+- 2 SPI controllers
+- 2 I2C controllers
+- 16 PWM channels
+- USB 1.1 controller (host/device)
+- 3 Programmable I/O (PIO) for custom peripherals
+- On-board LED
+- 1 Watchdog timer peripheral
+- Wiznet W5500 Ethernet MAC/PHY

+Pin Mapping
+===========
+
+The peripherals of the RP2350A SoC can be routed to various pins on the board.
+The configuration of these routes can be modified through DTS. Please refer to
+the datasheet to see the possible routings for each peripheral.
+
+External pin mapping on the W5500_EVB_PICO2 is identical to the Raspberry Pi
+Pico2. Since GPIO 25 is routed to the on-board LED on, similar to the Raspberry
+Pi Pico, the blinky example works as intended. The W5500 is routed to the SPI0
+(P16-P19), with the reset and interrupt signal for the W5500 routed to P20 and
+P21, respectively. All of these are shared with the edge connector on the
+board.
+
+Refer to `W55500 Evaluation Board Pico2 Documentation`_ for a board schematic and
+other certifications.

+Programming and Debugging
+*************************
+
+Flashing
+========
+
+Using OpenOCD
+-------------
+
+The overall explanation regarding flashing and debugging is the same as or
+``rpi_pico``.
+See :ref:`rpi_pico_flashing_using_openocd`. in ``rpi_pico`` documentation.
+
+A typical build command for w5500_evb_pico2 is as follows.
+This assumes a CMSIS-DAP adapter such as the RaspberryPi Debug Probe,
+but if you are using something else, specify ``RPI_PICO_DEBUG_ADAPTER``.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/basic/blinky
+   :board: w5500_evb_pico2
+   :goals: build flash
+   :gen-args: -DOPENOCD=/usr/local/bin/openocd
+
+Using UF2
+---------
+
+If you don't have an SWD adapter, you can flash the Raspberry Pi Pico with
+a UF2 file. By default, building an app for this board will generate a
+:file:`build/zephyr/zephyr.uf2` file. If the Pico is powered on with the ``BOOTSEL``
+button pressed, it will appear on the host as a mass storage device. The
+UF2 file should be drag-and-dropped to the device, which will flash the Pico.
+
+Debugging
+=========
+
+The SWD interface can also be used to debug the board. To achieve this, you can
+either use SEGGER JLink or OpenOCD.
+
+Using OpenOCD
+-------------
+
+Install OpenOCD as described for flashing the board.
+
+Here is an example for debugging the :zephyr:code-sample:`blinky` application.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/basic/blinky
+   :board: w5500_evb_pico2

+   :gen-args: -DOPENOCD=/usr/local/bin/openocd
