Clone/Initialize the repository

There are two ways of initializing this repository:

• Clone this repository with "git clone --recursive".

or

• Run "git clone" and then "git submodule update --init --recursive". This will bring in all the needed dependencies.

Build information

balenaOS currently only builds with cgroups v1. If your distribution defaults to using cgroups v2, please boot with the following kernel command line argument: systemd.unified_cgroup_hierarchy=0

Containerized build

• If you have a working docker installation, you can build in a containerized environment as follows: ./balena-yocto-scripts/build/balena-build.sh -d <device type> -s <shared directory>

  Where:

  • Device type is one of the supported devices with a valid <device type name>.coffee description file.
  • Shared directory is the absolute path to the build folder

Native build

To build all supported device types natively, please make sure your Linux distribution is supported by Yocto Project.

Additional host tools need to be installed for native builds to work.

• Run the barys build script: ./balena-yocto-scripts/build/barys

• You can also run barys with the -h switch to inspect the available options

Custom build using this repository

• Run the barys build script in dry run mode to setup an empty build directory ./balena-yocto-scripts/build/barys --remove-build --dry-run

• Edit the local.conf in the build/conf directory

• Prepare build's shell environment source layers/poky/oe-init-build-env

• Run bitbake (see message outputted when you sourced above for examples)

Build flags

• Consult layers/meta-balena/README.md for info on various build flags (setting up serial console support for example) and build prerequisites. Build flags can be set by using the build scripts (barys or balena-build) or by manually modifying local.conf.
