Hello Raspberry Pi Pico 2 (RP2350): first try MicroPython and CircuitPython

First try MicroPython/CircuitPython on Raspberry Pi Pico 2 (RP2350).

It's empty in fresh new Raspberry Pi Pico 2, it will power-up in Bootloader mode and RP2350 driver will appear as storage. 

Download firmware:

MicroPython:
- Visit https://micropython.org/download/RPI_PICO2/ to download MicroPython firmware for Pico2. Both normal RP2350 and RP2350-RISCV version are available.

CircuitPython:
- Visit https://circuitpython.org/board/raspberry_pi_pico2/ to download CircuitPython firmware for Pico 2 by Raspberry Pi.

To install MicroPython or CircuitPython firmware, simple drag the downloaded firmware (.uf2) to RP2350 driver.

To enter Bootloader mode:

Using BOOTSEL button:
Push and hold the BOOTSEL button as you plug your Pico 2 into your computer.

Using code:
If your Pico 2 have already been flashed MicroPython or CircuitPython, you can make it reboot in Boot load mode using code.

In MicroPython:

import machine
machine.bootloader()

In CircuitPython:

import microcontroller
microcontroller.on_next_reset(microcontroller.RunMode.BOOTLOADER)
microcontroller.reset()

Test code in the video:
