Steps to Reproduce

1.build project:

 

 

/lpg-build/cdc/fast_prod/WRL10_22/WRL10_22_GIT/wrlinux-10/setup.sh
 --machines=intel-socfpga-64 --distros=wrlinux --dl-layers --accept-eula=yes

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

bitbake-layers add-layer /net/pek-lpgtest20/buildarea1/renfeiqu/10_22/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 wrlinux-image-std

 

 2. run the testcase:
/opt/wr-test/main_test.py -k flash_char_block:"mtd1" -q
