use mkl-dnn on Danverton car branch2 platform shows"illegal instruction"

[JiaKun2017]

hi,
now i met a new issue, which about tranplant my lenet code using mkldnn to intel car branch2 board with denverton processor. now when i run the bin file in intel board, it only shows "Illegal instruction".
my steps as follows:
1) install intel sdk packet automated_driving_sdk_2019_beta.tgz
2) install mkldnn , before "make & make install" , i do the script as follows:
cd scripts && ./prepare_mkl.sh && cd ..
cmake CC=icc CXX=icpc cmake -DCMAKE_BUILD_TYPE=RELEASE ..
make
make install
3) create my project lenet, before i build the project , i will run a script like
/opt/intel/automated_driving_2019/system_studio_2019/bin/compilervars.sh intel64
after that i can use icc or icpc to compile my code.
4) build my project , use icc compiler, and -lmkldnn link flag to link mkldnn libs
5) when i run the bin file in linux machine, it will be ok. but when i run it in intel car branch2 board, it shows "Illegal instruction".

 i dont know why. and i check the lib in mkl-dnn\external\mklml_lnx_2019.0.1.20181227\lib . i can find libiomp5.so in intel sdk install directory, but i can not find libmklml_gnu.so and libmklml_intel.so. 

 can you give me some advice? thanks a lot.
