What is CROPS (CROssPlatformS)?

CROPS is an open source, cross-platform development framework that leverages Docker containers to provide an easily managed, extensible environment which allows developers to build binaries for a variety of architectures of Windows, Linux and Mac OS X hosts.

CROPS components

  • CEED - runs on the development host and exposes an API to Integrated Development Environments (IDEs) or CLI callers
  • TURFF - runs in a container and services requests from CODI
  • CODI - COntainer DIspatcher runs in a container and keeps track of all available TURFF instances in its internal table. CODI also redirects CEED requests to the corresponding TURFF instance

USING CROPS FOR ZEPHYR OS DEVELOPMENT

Please refer to the GitHub Wiki

USING CROPS WITH YOUR OWN TOOLCHAIN

  1. Install Docker (Linux) or Docker Toolbox (Windows/Mac)

  2. Build CODI dependencies container

Execute the following command from within the dockerfiles directory:

docker build -t crops/codi:deps -f Dockerfile.codi.deps .
  1. Build CODI container

Execute the following command from within the dockerfiles directory:

docker build -t crops/codi:version -f Dockerfile.codi ../
  1. Build toolchain dependencies container

Execute the following command from within the dockerfiles directory:

docker build -t crops/toolchain:deps -f Dockerfile.toolchain.deps .
  1. Open the Dockerfile.toolchain file and provide the URL to your toolchain

Example:

ENV TOOLCHAIN_NAME poky-glibc-x86_64-core-image-sato-i586-toolchain-2.0.sh
ENV TOOLCHAIN_PATH http://downloads.yoctoproject.org/releases/yocto/yocto-2.0/toolchain/x86_64/
  1. Build your toolchain container
docker build -t crops/toolchain:my_toolchain -f Dockerfile.toolchain ../
  1. Start CODI container
docker run -d --name codi-test -v /var/run/docker.sock:/var/run/docker.sock --net=host crops/codi:version
  1. Start toolchain container
mkdir -p $HOME/crops-workspace && docker run -d --name crops-toolchain-my_toolchain -v $HOME/crops-workspace/:/crops/   --env TURFFID=crops-toolchain-my_toolchain --net=host crops/toolchain:my_toolchain
  1. Run the Zephyr installer and answer "Yes" when prompted to install CEED. Answer "No" to all other questions
curl -kOs https://raw.githubusercontent.com/crops/crops/master/installers/zephyr-installer.sh && source   ./zephyr-installer.sh
  1. Place your project in the shared workspace

Example:

$HOME/crops-workspace/my_project/
  1. Build your project

Example:

$HOME/.crops/ceed/ceed -d crops-toolchain-my_toolchain -g "make -C /crops/my_project/"
  1. Share your toolchain with other developers by pushing it to Docker Hub

Example:

$docker push crops/toolchain:my_toolchain"
