TPM_E_NOT_PCR_BOUND
TPM_E_NOT_PCR_BOUND means the requested TPM key does not have the PCR binding information required by the operation.
What to check
- Confirm that the key was created with PCR binding when the consuming workflow requires platform-state binding.
- Do not expect an ordinary TPM key to provide measured-boot restrictions retroactively.
- Check the key policy and PCR selection against the device state expected by the application or attestation service.
