I see this misleading error multiple times as follows although TEE driver works pretty well.
Yes, this was all functionally tested.
Can you share your build instructions and testing approach?
Yes: it looks like you got all the kernel bits, but not the firmware. There are instructions for it here: https://github.com/microsoft/ms-tpm-20-ref
Once it's running, you can test it by running your favorite TPM usecases through /dev/tpm0.
