## Deploying firmware to the device
Firmware can be deployed to the device by putting it into bootloader mode
(hold down BOOTSEL while powering on or resetting) and then copying
`firmware.uf2` to the USB mass storage device that appears.
(hold down BOOTSEL while powering on or resetting) and then either copying
`firmware.uf2` to the USB mass storage device that appears, or using
`picotool load -x firmware.elf`. The latter command can be accessed
conveniently via `make deploy`.
If MicroPython is already installed then the bootloader can be entered by
executing `import machine; machine.bootloader()` at the REPL.
