Boot modes

After a reset, is executed. Depending on the dev_mode value in and whether the menu button (very top left of the board) is pressed, the board boots in different modes:

With dev_mode = False and the button not pressed, the board starts in "normal mode". The board will show up as a read-only flash drive on the computer, and settings changed in the boards menu will be saved automatically.

When the button is pressed, the board starts in "dev mode". In this case the board shows up read-write on the computer and will autoreload as the firmware is changed. While "dev mode" is active, settings changed on the board aren't saved.

If dev_mode = True in, things work the other way around: the board goes into "dev mode" by default, but will start in "normal mode" when the menu key is held during reset.
