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].
Supported Features

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.
