Basic usage

Set up build environment in poky workdir:

source oe-init-build-env rak831

Set up conf/bblayers.conf

# POKY_BBLAYERS_CONF_VERSION is increased each time build/conf/bblayers.conf
# changes incompatibly
POKY_BBLAYERS_CONF_VERSION = "2"

BBPATH = "${TOPDIR}"
BBFILES ?= ""

BBLAYERS ?= " \
  /workdir/poky/meta \
  /workdir/poky/meta-poky \
  /workdir/poky/meta-yocto-bsp \
  /workdir/poky/meta-raspberrypi \

  /workdir/poky/meta-openembedded/meta-python \
  /workdir/poky/meta-lora-net \
