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.

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.

Building and Flashing

Flashing

Here is an example for the 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:

$ minicom -D /dev/ttyACM0
# From the root of the zephyr repository
west build -b numaker_pfm_m467 samples/hello_world
west flash

Debugging

Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b numaker_pfm_m467 samples/hello_world
west debug

Step through the application in your debugger.
