Bootloader

Enter the bootloader in 3 ways:

Bootmagic reset: Hold down the top left key and plug in the keyboard. This will also clear the emulated EEPROM, so it is a good first step if the keyboard is misbehaving.
Physical reset button: Short the two holes in the PCB marked TP6 and plug the board in.
Keycode in layout: There is no key mapped to QK_BOOT in the pre-provided keymaps, but you may assign this key in any keymaps you create.

Flashing

After entering the bootloader through one of the three methods above, the keyboard will appear as a USB mass storage device named RPI-RP2. If the CLI is unable to find this device, the compiled .uf2 file can be manually copied to it. The keyboard will reboot on completion with the new firmware loaded.
