59Building and Flashing
60*********************
61Flashing
62========
63
64Here is an example for the :ref:`hello_world` application.
65
66On board debugger Nu-link-Me can emulate UART0 as a virtual COM port over usb,
67To enable this, set ISW1 DIP switch 1-3 (TXD RXD VOM) to ON.
68Connect the PFM M487 IoT to your host computer using the USB port, then
69run a serial host program to connect with your board. For example:
70
71.. code-block:: console
72
73   $ minicom -D /dev/ttyACM0
74
75.. zephyr-app-commands::
76   :zephyr-app: samples/hello_world
77   :board: nuvoton_pfm_m487
78   :goals: flash
79
80Debugging
81=========
82
83Here is an example for the :ref:`hello_world` application.
84
85.. zephyr-app-commands::
86   :zephyr-app: samples/hello_world
87   :board: nuvoton_pfm_m487
88   :goals: debug
89
90Step through the application in your debugger.
