Description

If the kernel is built with CONFIG_FTRACE_STARTUP_TEST=y, the self-test process during system startup will fail, causing the system to hang in an infinite loop at a certain test, as shown below:

source environment-setup-x86_64-wrlinuxsdk-linux
source oe-init-build-env build
echo 'BB_NUMBER_THREADS ?= "24"' >> conf/local.conf
echo 'PARALLEL_MAKE ?= "-j 24"' >> conf/local.conf
bitbake-layers add-layer /lpg-build/cdc/WASSP_LINUX_1025/testcases/wrlinux/wr-testing/kts-dev
cd /lpg-build/cdc/WASSP_LINUX_1025/testcases/wrlinux/wr-testing/kts-dev/tools && ./gen_kernel_plan.py -s wr-kts -b nxp-imx6 -k standard -a arm -p $BUILDDIR ; cd - && cp standard_wr-kts.ini test_plan.list

#####To Clone a whole new testcases layer#####
git clone --depth 1 -b master git://lxgit.wrs.com/wrlinux-testing/testcases.git ../layers/testcases/wrlinux/
bitbake-layers add-layer ../layers/testcases/wrlinux/wr-testing/kts-dev
cd ../layers/testcases/wrlinux/wr-testing/kts-dev/tools && ./gen_kernel_plan.py -s wr-kts -b nxp-imx6 -k standard -a arm -p $BUILDDIR ; cd - && cp standard_wr-kts.ini test_plan.list
#####End#####

echo 'IMAGE_FSTYPES += "tar.bz2"' >> conf/local.conf
echo 'IMAGE_FSTYPES:remove = " live hddimg iso"' >> conf/local.conf
echo 'require templates/feature/wr-kts/template.conf' >> conf/local.conf

open the following kernels configs:
  CONFIG_FTRACE_STARTUP_TEST=y
    CONFIG_EVENT_TRACE_TEST_SYSCALLS=y
    CONFIG_IRQSOFF_TRACER=y
    CONFIG_PREEMPT_TRACER=y
    CONFIG_FTRACE=y
    CONFIG_LOG_BUF_SHIFT=22
bitbake wrlinux-image-std
