I’m looking to tinker with my framework 13 (AMD AI 340)’s TPM for use with device attestation, but am having trouble finding the correct chain of trust for the Endorsement Key Certificate. I looked through the microsoft provided TPM root/intermediate certs: Install trusted TPM root certificates | Microsoft Learn but cannot find the correct next intermediate CA. Any ideas on how to progress?
PS. The AMD root certs mention that the manufacturer-id is Microsoft (which mine is) and I found a couple certs with DFID00B20F40 in their Subject which mine does as well, but i can’t find the full chain.
