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.

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

.. zephyr:board-supported-hw::

The on-board 12-MHz crystal allows the device to run at its maximum operating speed of 200MHz.

More details about the supported peripherals are available in M460 TRM_

Building and Flashing

.. zephyr:board-supported-runners::

Flashing

Here is an example for the :zephyr:code-sample: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 :zephyr:code-sample:hello_world application.

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: numaker_pfm_m467 :goals: debug

Step through the application in your debugger.

VS Code Support

Here is to go through VS Code instead of command line.
