The steps to do fastRPC sanity test is: 1.download code p4 login export PATH="$PATH:/prj/qct/asw/qctss/linux/bin/vce" vce.py view --base fastrpctest.common.1.0 --checkout=<username> --root . 2.compile command chmod -R 777 ./fastrpc_tests && python3 ./fastrpc_tests/build_fastrpc_test.py -target=LE 3.run fastRPC test fastrpc_tests_ReleaseG_push_LE.bat adb shell fastrpc_tests -e (case number) -d 3

That said, I am not sure whether I'd be against fixing up the devicetree component.. Konrad
