| Overview |
| ******** |
| |
| The NuMaker PFM M487 is an Internet of Things (IoT) application focused platform |
| specially developed by Nuvoton. The PFM-M487 is based on the NuMicro® M487 |
| Ethernet series MCU with ARM® -Cortex®-M4F core. |

| Supported Features |
| ================== |
| |
| * The on-board 12-MHz crystal allows the device to run at its maximum operating speed of 192MHz. |
| |
| 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 | |
| +-----------+------------+-----------------------+ |
| |
| Other hardware features are not yet supported on Zephyr porting. |

| More details about the supported peripherals are available in `M480 TRM`_ |
| Other hardware features are not currently supported by the Zephyr kernel. |
| |
| Building and Flashing |
| ********************* |
| Flashing |
| ======== |
| |
| Here is an example for the :ref:`hello_world` application. |
| |
| On board debugger Nu-link-Me 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 M487 IoT to your host computer using the USB port, then |
| run a serial host program to connect with your board. For example: |
| |
| .. code-block:: console |
| |
| $ minicom -D /dev/ttyACM0 |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: nuvoton_pfm_m487 |
| :goals: flash |
| |
| Debugging |
| ========= |
| |
| Here is an example for the :ref:`hello_world` application. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: nuvoton_pfm_m487 |
| :goals: debug |
| |
| Step through the application in your debugger. |
