LibTPM2.0 integration with platform

[Suresh Panara]

Hi Ken,
We already have SW TPM1.2 integrated in our platform and now looking forward for integrating SW TPM2.0.
Is there any soft of doc available describing the global interface functions I supposed to be using from my platform?
I could see,
_TPM_Init : I assume its an equivalent of TPM_MainInit (TPM1.2)
ExecCommand : TPM_ProcessA (TPM1.2)

Is my understanding correct?

Is there any guide for migrating from TPM1.2 to TPM2.0 available? I am looking for startup sequence to initiate at power on

Thanks

The TPM 2.0 code (which this project got from the TPM spec) was not designed to be callable directly. It was designed for a socket interface.

It you need direct calls, rpcSendCommand() seems like a good entry. For initialization, perhaps rpcSignalPowerOn()?

I have not tested this.

Perhaps this will also give you some clues. https://github.com/stefanberger/libtpms/blob/master/src/tpm_tpm2_interface.c
