{tag=Run Zephyr on X}

<Zephyr> docs: https://docs.zephyrproject.org/latest/boards/raspberrypi/rpi_pico/doc/index.html

Note that the <LED blinker> example does not work on the <Raspberry Pi Pico W>, see also: <Run Zephyr on Raspberry Pi Pico W>.

You can speed up the debug loop a little bit by plugging the Pi with BOOTSEL selected, and then running:
``
west flash --runner uf2
``
This flashes the image, and immediately turns off BOOTSEL mode and runs the program.

However to run again you need to unplug the USB and re-plug with BOOTSEL again so it is still painful.

Run Zephyr on Raspberry Pi Pico

The Zephir <LED blinker> example does not work on the <Raspberry Pi Pico W> because the on-board LED is wired differently. But the hello world works and with:
``
screen /dev/ttyUSB0 115200
``
host shows:
``
*** Booting Zephyr OS build v4.2.0-491-g47b07e5a09ef ***
Hello World! rpi_pico/rp2040
``
Nice!

Run Zephyr on Raspberry Pi Pico W

{c}

= Blinky
{synonym}
{title2}

This is the <hello world> program of <microcontrollers>: blinking and <LED>! Many boards have an on-board <LED>, making this a convenient hello world that does not require any external components.
