What does HRESULT 0x80280055 (TPM_E_DAA_STAGE) mean?

TPM_E_DAA_STAGE

TPM_E_DAA_STAGE: diagnose the owning boundary

TPM_E_DAA_STAGE (0x80280055) is documented as The atomic process indicated by the submitted DAA command is not the expected process. Treat that wording as the specific TPM 1.2 DAA stage ordering boundary; it is more useful than a generic “component failed” label.

Evidence that matters

Record the requested DAA command and current TPM/issuer stage. Resume with the command expected for that exact stage instead of skipping or replaying protocol steps.

Interpretation and verification

Keep the affected object and caller identity stable while changing only the rejected prerequisite. The correction is proven when the original operation crosses this boundary with the intended state or output. If a different HRESULT appears afterward, preserve it as a separate later-stage result rather than folding it back into TPM_E_DAA_STAGE.
