You can find this file in the BSP Layer at:
meta-bsp_name
/conf/layer.conf
The conf/layer.conf
file identifies the file structure as a
layer, identifies the
contents of the layer, and contains information about how the build
system should use it.
Generally, a standard boilerplate file such as the following works.
In the following example, you would replace "bsp
" and
"_bsp
" with the actual name
of the BSP (i.e. bsp_name
from the example template).
# We have a conf and classes directory, add to BBPATH BBPATH .= ":${LAYERDIR}" # We have a recipes directory, add to BBFILES BBFILES += "${LAYERDIR}/recipes-*/*/*.bb \ ${LAYERDIR}/recipes-*/*/*.bbappend" BBFILE_COLLECTIONS += "bsp" BBFILE_PATTERN_bsp = "^${LAYERDIR}/" BBFILE_PRIORITY_bsp = "6"
To illustrate the string substitutions, here are the corresponding statements
from the Crown Bay conf/layer.conf
file:
BBFILE_COLLECTIONS += "crownbay" BBFILE_PATTERN_crownbay = "^${LAYERDIR}/" BBFILE_PRIORITY_crownbay = "6"
This file simply makes BitBake aware of the recipes and configuration directories. The file must exist so that the OpenEmbedded build system can recognize the BSP.
