Welcome to [Flipper Zero](https://flipperzero.one/)'s Custom Firmware repo!
Our goal is to make any features possible in this device without any stupid limitations! Please help us realize emulation for all dynamic (rolling codes) protocols and brute-force app!
# Update firmware
[Get Latest Firmware from Update Server](https://github.com/Eng1n33r/flipperzero-firmware)
Flipper Zero's firmware consists of two components:
- Core2 firmware set - proprietary components by ST: FUS + radio stack. FUS is flashed at factory and you should never update it.
- Core1 Firmware - HAL + OS + Drivers + Applications.
They both must be flashed in order described.
## With STLink
### Core1 Firmware
Prerequisites:
- Linux / macOS
- Terminal
- [arm-gcc-none-eabi](https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads)
- openocd
One liner: `make flash`
### Core2 flashing procedures
Prerequisites:
- Linux / macOS
- Terminal
- STM32_Programmer_CLI (v2.5.0) added to $PATH
One liner: `make flash_radio`
## With USB DFU
1. Download latest [Firmware](https://update.flipperzero.one)
2. Reboot Flipper to Bootloader
- Press and hold `← Left` + `↩ Back` for reset
- Release `↩ Back` and keep holding `← Left` until blue LED lights up
- Release `← Left`
<!-- ![Switch to DFU sequence](https://habrastorage.org/webt/uu/c3/g2/uuc3g2n36f2sju19rskcvjzjf6w.png) -->
3. Run `dfu-util -D full.dfu -a 0`
# Build with Docker
## Prerequisites
1. Install [Docker Engine and Docker Compose](https://www.docker.com/get-started)
2. Prepare the container:
```sh
docker-compose up -d
```
## Compile everything
```sh
docker-compose exec dev make
```
Check `dist/` for build outputs.
Use **`flipper-z-{target}-full-{suffix}.dfu`** to flash your device.
# Build on Linux/macOS
## macOS Prerequisites
Make sure you have [brew](https://brew.sh) and install all the dependencies:
```sh
brew bundle --verbose
```
## Linux Prerequisites
### gcc-arm-none-eabi
```sh
toolchain="gcc-arm-none-eabi-10.3-2021.10"
toolchain_package="$toolchain-$(uname -m)-linux"
wget -P /opt "https://developer.arm.com/-/media/Files/downloads/gnu-rm/10.3-2021.10/$toolchain_package.tar.bz2"
tar xjf /opt/$toolchain_package.tar.bz2 -C /opt
rm /opt/$toolchain_package.tar.bz2
for file in /opt/$toolchain/bin/* ; do ln -s "${file}" "/usr/bin/$(basename ${file})" ; done
```
### Optional dependencies
- openocd (debugging/flashing over SWD)
- heatshrink (compiling image assets)
- clang-format (code formatting)
- dfu-util (flashing over USB DFU)
- protobuf (compiling proto sources)
For example, to install them on Debian, use:
```sh
apt update
apt install openocd clang-format-13 dfu-util protobuf-compiler
```
heatshrink has to be compiled [from sources](https://github.com/atomicobject/heatshrink).
## Compile everything
```sh
make
```
Check `dist/` for build outputs.
Use **`flipper-z-{target}-full-{suffix}.dfu`** to flash your device.
## Flash everything
Connect your device via ST-Link and run:
```sh
make whole
```
