Flipper Zero Firmware

Discord

Show me the code

Welcome to Flipper Zero's Firmware repo! Our goal is to create nice and clean code with good documentation, to make it a pleasure for everyone to work with.

Update firmware

Get Latest Firmware from Update Server

Flipper Zero's firmware consists of three components:

  • Core2 firmware set - proprietary components 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:

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 Back and keep holding Left until blue LED lights up
  • Release Left
  1. Run dfu-util -D full.dfu -a 0

Build from source

Prerequisites

  1. Install Docker Engine and Docker Compose
  2. Clone the repo:
    git clone https://github.com/flipperdevices/flipperzero-firmware
    cd flipperzero-firmware
    
  3. Prepare the container:
    docker-compose up -d
    

Compile everything

docker-compose exec dev make -j$(nproc)

Flash everything

docker-compose exec dev make -j$(nproc) whole

Compile bootloader

docker-compose exec dev make -j$(nproc) -C bootloader

Bootloader compilation results:

  • bootloader/.obj/f7/bootloader.elf
  • bootloader/.obj/f7/bootloader.hex
  • bootloader/.obj/f7/bootloader.bin
  • bootloader/.obj/f7/bootloader.dfu - should be used to flash

Compile firmware

docker-compose exec dev make -j$(nproc) -C firmware

Firmware compilation results:

  • firmware/.obj/f7/firmware.elf
  • firmware/.obj/f7/firmware.hex
  • firmware/.obj/f7/firmware.bin
  • firmware/.obj/f7/firmware.dfu - should be used to flash

Concatenate bootloader and firmware

You might want to do this to distribute the firmware as a single file.

That's exactly how we generate our full builds.

  1. Concatenate HEX files:
    docker-compose exec dev srec_cat \
     bootloader/.obj/f7/bootloader.hex -Intel \
     firmware/.obj/f7/firmware.hex -Intel \
     -o firmware/.obj/f7/full.hex -Intel
    
  2. Convert HEX to DFU:
    docker-compose exec dev hex2dfu \
     -i firmware/.obj/f7/full.hex \
     -o firmware/.obj/f7/full.dfu \
     -l "Flipper Zero F7"
    

Finally, you will have firmware/.obj/f7/full.dfu file that can be distributed and flashed.
