Welcome to [Flipper Zero](https://flipperzero.one/)'s Firmware repo!
Our goal is to create nice and clean code along with good documentation, to make it a pleasure for everyone to work with.
This repo will become completely public closer to the device shipping date.

# Update firmware

Flipper Zero's firmware consists of three components:

- Core2 firmware set - proprietary componenets by ST: FUS + radio stack.
- Core1 Bootloader - controls basic hardware initialization and loads firmware
- Core1 Firmware - HAL + OS + Drivers + Applications

All 3 of them must be flashed in order described.
