+NUVOTON NUMAKER PFM M467
+########################
+
+Overview
+********
+
+The NuMaker PFM M467 is an Internet of Things (IoT) application focused platform
+specially developed by Nuvoton. The PFM-M467 is based on the NuMicro® M467
+Ethernet series MCU with ARM® -Cortex®-M4F core.
+
+.. image:: ./pfm_m467.jpeg

+   :align: center
+   :alt: PFM-M467
+
+Features:
+=========
+- 32-bit Arm Cortex®-M4 M467HJHAE MCU
+- Core clock up to 200 MHz
+- 1024 KB embedded Dual Bank Flash and 512 KB SRAM
+- Ethernet (IP101GR) for network application
+- USB 2.0 High-Speed OTG / Host / Device
+- USB 1.1 Full-Speed OTG / Host / Device
+- External SPI Flash (Winbond W25Q20) which can be regarded as ROM module
+- MicroSD Card slot for T-Flash
+- Arduino UNO compatible interface
+- Three push-buttons: one is for reset and the other two are for user-defined
+- Four LEDs: one is for power indication and the other three are for user-defined
+- On-board NU-Link2 ICE debugger/programmer with SWD connector
+
+More information about the board can be found at the `PFM M467 User Manual`_.
+
+Supported Features
+==================
+
+* The on-board 12-MHz crystal allows the device to run at its maximum operating speed of 200MHz.
+
+The development board configuration supports the following hardware features:
+
++-----------+------------+-----------------------+
+| Interface | Controller | Driver/Component      |
++===========+============+=======================+
+| NVIC      | on-chip    | nested vectored       |
+|           |            | interrupt controller  |
++-----------+------------+-----------------------+
+| SYSTICK   | on-chip    | system clock          |
++-----------+------------+-----------------------+
+| UART      | on-chip    | serial port           |
++-----------+------------+-----------------------+
+| GPIO      | on-chip    | gpio                  |
++-----------+------------+-----------------------+
+
+Other hardware features are not yet supported on Zephyr porting.
+
+More details about the supported peripherals are available in `M460 TRM`_
+Other hardware features are not currently supported by the Zephyr kernel.
+
+Building and Flashing
+*********************
+Flashing
+========
+
+Here is an example for the :ref:`hello_world` application.
+
+On board debugger Nu-link2 can emulate UART0 as a virtual COM port over usb,
+To enable this, set ISW1 DIP switch 1-3 (TXD RXD VOM) to ON.
+Connect the PFM M467 IoT to your host computer using the USB port, then
+run a serial host program to connect with your board. For example:
+
+.. code-block:: console
+
+   $ minicom -D /dev/ttyACM0
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: numaker_pfm_m467
+   :goals: flash
+
+Debugging
+=========
+
+Here is an example for the :ref:`hello_world` application.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: numaker_pfm_m467
+   :goals: debug
+
+Step through the application in your debugger.
