Crazyflie 1.0/2.0 Firmware Build Status

This project contains the source code for the Crazyflie 1.0/2.0 firmware.

Dependencies

You'll need to use either the Crazyflie VM, the toolbelt or install some ARM toolchain.

Install a toolchain

OS X

brew tap PX4/homebrew-px4
brew install gcc-arm-none-eabi

Debian/Ubuntu

Tested on Ubuntu 14.04 64b:

sudo add-apt-repository ppa:terry.guo/gcc-arm-embedded
sudo apt-get update
sudo apt-get install libnewlib-arm-none-eabi

Arch Linux

sudo pacman -S community/arm-none-eabi-gcc community/arm-none-eabi-gdb community/arm-none-eabi-newlib

Windows

Cloning

This repository uses git submodules. Clone with the --recursive flag

git clone --recursive https://github.com/bitcraze/crazyflie-firmware.git

If you already have cloned the repo, use

git submodule init
git submodule update

Compiling

Crazyflie 1.0

Build with:

make PLATFORM=CF1

or with the toolbelt

tb build PLATFORM=CF1

Crazyflie 2.0

This is the dafault build so just running "make" is enough or:

make PLATFORM=CF2

or with the toolbelt

tb build

config.mk

To create custom build options create a file called config.mk in the root folder (same as Makefile) and fill it with options. E.g.

PLATFORM=CF1
DEBUG=1
CLOAD=0

More information can be found on the Bitcraze wiki

Make targets:

all        : Shortcut for build
compile    : Compile cflie.hex. WARNING: Do NOT update version.c
build      : Update version.c and compile cflie.elf/hex
clean_o    : Clean only the Objects files, keep the executables (ie .elf, .hex)
clean      : Clean every compiled files
mrproper   : Clean every compiled files and the classical editors backup files

cload      : If the crazyflie-clients-python is placed on the same directory level and 
             the Crazyradio/Crazyradio PA is inserted it will try to flash the firmware 
             using the wireless bootloader.
flash      : Flash .elf using OpenOCD
halt       : Halt the target using OpenOCD
reset      : Reset the target using OpenOCD
openocd    : Launch OpenOCD

Unit testing

Dependencies

Frameworks for unit testing are pulled in as git submodules.

The testing framework uses ruby and rake to generate and run code.

To minimize the need for installations and configuration, use the docker builder image (bitcraze/builder) that contains all tools needed. All scripts in the tools/build directory are intended to be run in the image. The toolbelt makes it easy to run the tool scripts.

Running unit tests

With the environment set up locally

    rake

with the docker builder image and the toolbelt
