Steps to Reproduce

1.     build a project

/lpg-build/cdc/fast_prod/WRLINUX_CI/RC_GIT/wrlinux-10/setup.sh --machines=ti-j72xx --distros=wrlinux --dl-layers --accept-eula=yes

. ./environment-setup-x86_64-wrlinuxsdk-linux
. ./oe-init-build-env build_test

bitbake-layers add-layer /buildarea1/renfeiqu/master_wr/testcases/wr-testing/bts-dev/

echo "require templates/feature/bts/template.conf" >> conf/local.conf

echo BB_NUMBER_THREADS ?= \"24\" >> conf/local.conf

echo PARALLEL_MAKE ?= \"-j 24\" >> conf/local.conf

echo "WRTEMPLATE_append = \" feature/docker feature/target-toolchain \"" >> conf/local.conf

bitbake lib32-wrlinux-image-std

 

2.boot up the board and run the testcase.
