How to test and modify fTPM (enabled with buildroot package) #774

Open graziadonghia opened 1 month ago

graziadonghia commented 1 month ago

I am trying to implement a fTPM through tpm2-tools and tpm2-tss within OP-TEE. Firstly, I saw this implementation, but I could not build it because it was probably tested with an older version of OP-TEE. However, #480 has added support for fTPM through buildroot packages, so it should be included in the latest version of OP-TEE. Having said that, how can I execute measured boot and tpm functionalities, after building OP-TEE with buildroot?

480 does if I understand it correctly only cover the rootfs part of fTPM. You still need to compile an fTPM TA for OP-TEE.

Is there a current implementation of an fTPM TA for the latest version of OP-TEE?
