To build all the CCGX rootfs or images with all the existing recipes, see instructions here: https://github.com/victronenergy/venus/blob/master/README.

Below guide is an introduction on how to add recipes and create/debug them.

Start bitbake:

  make bb
  

Build a single recipe:

  bitbake -b dbus-modbustcp_0.7.2.bb
  

That probably didn't work, because dependencies are missing. To build the recipe including dependencies, do:

  bitbake dbus-modbustcp
