Flipper Zero Firmware community repo

Welcome to Flipper Zero'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 - 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.
