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

Get Latest Firmware from Update Server

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

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)
