Modifications

The Raspberry-Pi Pico is pre-loaded with an UF2 bootloader in the RP2040 microcontroler ROM. U2F mode makes the board looking like a USB Flash Drive when attached to a computer. It allows to upload a new firmware into the Flash.

The MicroPython firmware is already uploaded while manufacturing the Pico board. So, ''in fine'', there is no need to activates UF2 mode anymore. MicroPython does allows to store python scripts into the board via operation over the serial port (no need for UF2 mode in this case).

Pressing the "boot" button while powering up the Pico will activates the UF2 mode. Simply drag an UF2 firmware on the USB Flash drive to completely reprogram the firmware running on the board (No special tools, No special drivers needed)! The UF2 bootloader can be used to load up a newer version of MicroPython, Arduino IDE compiled firmware, C++ firmware, CircuitPython (derivative version of MicroPython made from Adafruit Industries), etc.
