Development Mode

All Flipper devices shipped in the first production batch ship in development mode. Development mode is a mode that makes it easy to perform firmware updates to both chips without external hardware attached.

To launch the software after applying a firmware update, you must “boot” your Flipper device. This can be accomplished with the dfu-programmer utility.

macOS

dfu-programmer atmega32u2 launch —-no-reset
