Contributing

<<<<<<< HEAD Welcome to the Wetox Flipper Zero's Firmware repo! This is a modified unofficial version of the Flipper Zero firmware with some additional features.

If you want to incorporate our features into your firmware fork, please contact us beforehand!

Feature list

• Removing T5577 passwords via the cli command rfid clear_pass_t5577 using a dictionary attack
• Support for inverted screens via a toggle in the desktop settings ======= Our main goal is to build a healthy and sustainable community around Flipper, so we're open to any new ideas and contributions. We also have some rules and taboos here, so please read this page and our Code of Conduct carefully.

I need help

The best place to search for answers is our User Documentation. If you can't find the answer there, check our Discord Server or our Forum.

I want to report an issue

If you've found an issue and want to report it, please check our Issues page. Make sure the description contains information about the firmware version you're using, your platform, and a clear explanation of the steps to reproduce the issue.

I want to contribute code

Before opening a PR, please confirm that your changes must be contained in the firmware. Many ideas can easily be implemented as external applications and published in the Flipper Application Catalog. If you are unsure, reach out to us on the Discord Server or the Issues page, and we'll help you find the right place for your code.

Also, please read our Contribution Guide and our Coding Style, and make sure your code is compatible with our Project License.

Finally, open a Pull Request and make sure that CI/CD statuses are all green.

Development

Flipper Zero Firmware is written in C, with some bits and pieces written in C++ and armv7m assembly languages. An intermediate level of C knowledge is recommended for comfortable programming. C, C++, and armv7m assembly languages are supported for Flipper applications.

Firmware RoadMap

Requirements

Supported development platforms:

• Windows 10+ with PowerShell and Git (x86_64)
• macOS 12+ with Command Line tools (x86_64, arm64)
• Ubuntu 20.04+ with build-essential and Git (x86_64)

Supported in-circuit debuggers (optional but highly recommended):

• Flipper Zero Wi-Fi Development Board
• ST-Link
• J-Link

Flipper Build System will take care of all the other dependencies.

Cloning source code

Make sure you have enough space and clone the source code:

git clone --recursive https://github.com/flipperdevices/flipperzero-firmware.git

Building

<<<<<<< HEAD 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 the order described.

With offline update package

With Flipper attached over USB:

./fbt flash_usb

Just building the package:

./fbt updater_package

To update, copy the resulting directory to Flipper's SD card and navigate to update.fuf file in Archive app.

With STLink

Core1 Firmware

Prerequisites:

• Linux / macOS
• Terminal
• arm-gcc-none-eabi
• openocd

One liner: ./fbt firmware_flash

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

3. Run dfu-util -D full.dfu -a 0

Build with Docker

Prerequisites

1. Install Docker Engine and Docker Compose
2. Prepare the container:

docker-compose up -d

Compile everything

docker-compose exec dev ./fbt

Check dist/ for build outputs.

Use flipper-z-{target}-full-{suffix}.dfu to flash your device.

If compilation fails, make sure all submodules are all initialized. Either clone with --recursive or use git submodule update --init --recursive.

Build on Linux/macOS

Check out documentation/fbt.md for details on building and flashing firmware.

macOS Prerequisites

Make sure you have brew and install all the dependencies:

brew bundle --verbose

Linux Prerequisites

gcc-arm-none-eabi

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:

apt update
apt install openocd clang-format-13 dfu-util protobuf-compiler

heatshrink has to be compiled from sources.

Compile everything

=======
Build firmware using Flipper Build Tool:

```shell
>>>>>>> upstream/dev
./fbt

Flashing firmware using an in-circuit debugger

Connect your in-circuit debugger to your Flipper and flash firmware using Flipper Build Tool:

./fbt flash

Or connect via the blackmagic board and run:

BLACKMAGIC=<board's IP>:2345 make blackmagic_load

Flashing firmware using USB

<<<<<<< HEAD

• Telegram: @wetox_flipper ======= Make sure your Flipper is on, and your firmware is functioning. Connect your Flipper with a USB cable and flash firmware using Flipper Build Tool:

./fbt flash_usb
