Steps to Reproduce

1.build project

/lpg-build/cdc/fast_prod/WRLINUX_MASTER_WR/MASTER_WR_GIT/wrlinux-10/setup.sh --machines=ti-j72xx --distro wrlinux-graphics --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/kts-dev/

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

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

echo "WRTEMPLATE_append = \" feature/wr-kts feature/target-toolchain feature/bcc \"" >> conf/local.conf

echo "KERNEL_FEATURES_append = \" bsp/ti-j72xx/ti-j72xx-remoteproc.scc\"" >> conf/local.conf

bitbake wrlinux-image-std-sato

2.boot up the board and run the kts test groups
