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.

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 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
