| Overview |
| ******** |
| |
| The NuMaker M2L31KI is an Internet of Things (IoT) application focused platform |
| specially developed by Nuvoton. The NuMaker-M2L31KI is based on the NuMicro® M2L31 |
| series MCU with ARM® -Cortex®-M23 core. |

| More details about the supported peripherals are available in `M2L31 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-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 NuMaker-M2L31KI 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: numaker_m2l31ki |
| :goals: flash |
| |
| Debugging |
| ========= |
| |
| Here is an example for the :ref:`hello_world` application. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: numaker_m2l31ki |
| :goals: debug |
| |
| Step through the application in your debugger. |
