Hi @horver ,
Are you using the /dev/spidev interface, /dev/tpm0, Windows TBS or something else to communicate with the TPM? The TPM2_Clear is only allowed when using the locality 0, which is our default when using the internal TIS layer and /dev/spidev. Do other TPM command was fine? Perhaps this TPM has a policy auth set to prevent this without authenticating. Have you reviewed the TPM 2.0 specification around the TPM2_Clear command?
Thanks,

Hi @horver ,
Some time has passed with no update, so I wanted to check in. Did you find a resolution to this issue?
Note it is possible to disable the TPM2_Clear
with the TPM2_ClearControl
.
