Using UF2
---------
If you don't have an SWD adapter, you can flash the Raspberry Pi Pico with
a UF2 file. By default, building an app for this board will generate a
`build/zephyr/zephyr.uf2` file. If the Pico is powered on with the `BOOTSEL`
button pressed, it will appear on the host as a mass storage device. The
UF2 file should be drag-and-dropped to the device, which will flash the Pico.
