I compiled the sample code SampleCode/LocalAttestation in hardware mode and ran it with error listed below(it runs ok when compiled in SIMULATION mode).

You can try to enter bin folder and then run the application. Please refer to https://github.com/intel/linux-sgx/blob/master/SampleCode/LocalAttestation/README.txt#L29
