Hello muye,

Did you try running the RemoteAttestation sample in the SGX SDK?

Infact ,I did my attestation and get the result GROUP_OUT_OF_DATE form IAS.  After I updated the newest  BIOS,  compiling is ok,but sgx_init_quote always returns 1 when running . Then removing all and reinstall sgx development environment does not help.

Hello Muye,

After upgrading your BIOS, did you ensure that SGX is enabled? Execute cpuid | grep -i sgx

Thank you for your replaying.   After executing    cpuid | grep -i sgx   ,it shows it is normal .

It's very kind of you for you replay again. I   have fixed it. 

Steps are as follows:     Uninstall SGX PSW  ,disable SGX in BIOS ,reboot, enable SGX,reinstall PSW. 

Sincerely,

muye
