[tpm2] Esys_CreatePrimary works with Simulator but failing with /dev/tpm0

Dear team, I am trying to create a primary key using Esys_CreatePrimary. The code works without any issues when trying on the simulator, but fails when trying on a hardware TPM using /dev/tpm0 The error I am getting is: WARNING:esys:src/tss2-esys/api/Esys_CreatePrimary.c:423:Esys_CreatePrimary_Finish() Received TPM Error ERROR:esys:src/tss2-esys/api/Esys_CreatePrimary.c:164:Esys_CreatePrimary() Esys Finish ErrorCode (0x000001c2) Esys_CreatePrimary fail Can someone point out why I am getting this error? So far I am unable to pinpoint the problem. Best regards, Sourajit Mukhopadhyay
