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.

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.
