Hello,
I know this question is not directly related to the TSS project, but maybe there is one someone in this community who can help me with this.
I am using a TPM Optiga Infineon SLB 9670 on a Raspberry pi 4 I/O board with a compute module 4.
This TPM has a physical reset button. The problem is that I cannot manage to reset the TPM. No matter how I place the jumper or how long I press the button, the TPM is not resetting.
I believe the reset is not carried out, because when I try to re-provision with tss2_provision I get the message “SRK persistent handle already defined”.
Moreover, if I call “sudo tpm2_getcap handles-persistent” I get the handles which I have already previously occupied (I am assuming here that after a reset they will be emptied).
Has anyone done a physical reset of a TPM?
Thanks for your help.
