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

<a href="https://update.flipperzero.one/">Get Latest Firmware from Update Server</a>


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.

## With STLink

### Core2 flashing procedures

Prerequisites:

- Linux / MacOs
- Terminal
- STM32_Programmer_CLI added to $PATH

One liner: `./flash_core2_ble.sh`

### Core1 Bootloader + Firmware

Prerequisites:

- Linux / MacOs
- Terminal
- Arm gcc noneabi
- openocd

One liner: `./flash_core1_main.sh`

## With USB DFU 

1. Download latest [Firmware](https://update.flipperzero.one)

2. Reboot Flipper to Bootloader 
 - Press and hold `← Left` + `↩ Back` for reset 
 - Release `← Left` and keep holding `↩ Back` until blue LED lights up
 - Release `↩ Back`

1. Run `dfu-util -D full.dfu -a 0`

# Build from source

`docker-compose exec dev make -C firmware flash` for build and flash dev board (see `applications/applications.mk` for list of applications/examples)
