$ cd qmk_firmware
# Put the XIAO RP2040 into bootloader mode the first time:
# Hold the BOOT button, press the RESET button, then release BOOT.
# Or, connect while holding BOOT. It should appear as a USB drive (RPI-RP2).
# If using Linux, you might need to mount it (e.g., using udisksctl):
# $ udisksctl mount -b /dev/disk/by-label/RPI-RP2
$ qmk flash -kb likeablob/spin_maru -km default
# For subsequent flashes:
# Double-click the bottom reset switch quickly to enter bootloader mode.
# Then, run the 'qmk flash' command again.
