To Get The Testing Layer:
------------------------
# git clone ssh://git@lxgit.wrs.com/wrlinux-testing/testcases
# cd wrlinux;git checkout master
Project Build:
----------------------
--machines=xilinx-zynq --distro wrlinux --dl-layers
Build Steps:
. oe-init-build-env
Add KTS layer
1.bitbake-layers add-layer <path to wr-testing/kts-dev>
2.echo "require templates/feature/wr-kts/template.conf" >> conf/local.conf
3.echo 'PREFERRED_PROVIDER_virtual/kernel = "linux-yocto"' >> conf/local.conf
build image:
# bitbake wrlinux-image-glibc-std
On a target:
/opt/wr-test/main_test.py -s stress-ng-context_switch
