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.

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 [1].

Building and Flashing

The numaker_pfm_m467 board supports the runners and associated west commands listed below.

flash debug

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.

VS Code Support

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