# This is an example script showing how to compare configs on hayato
# Usage of this script:
# - set the three variables below
# - set up the ecos.conf3 file as follows:
# $ make print-configs BOARD=hayato >econ.conf
# $ grep CONFIG ecos.conf |sort |uniq >ecos.conf2
# $ cat ecos.conf2 |awk '{print $1}' >ecos.conf3
# - configure and build hayato for zephyr
# $ zmake configure -B /tmp/z/hay zephyr/projects/asurada/hayato/ -t zephyr -b
# - run this script to check for CONFIG mismatches
# $ zephyr/get_cfg.sh
set -e
dir=/tmp/z/hay
subdir=build-singleimage
in=~/cosarm/src/platform/ec/ecos.conf3
cd "${dir}"
pushd "${subdir}"
# This is created by running:
#
# ninja -v -C /tmp/z/hay/build-singleimage
#
# then replacing '-C' by '-E -dM'
# The idea is to get a list of the #defines used to compile the code
