Hi Dan, I've been using [1] with [2] as simulator for playing around with TPM 2.0 features, because I can wire it to QEMU and launch a VM with EDK2 UEFI. No precompiled packages for any of these. So I was testing master version from both tpm2-tools and abrmd with the release candidates for tss and I noticed this error on tpm2_pcrlist after this commit [3] enabling SHA512 and I related to this thread... I'm not sure yet if this is a simulator problem or something on tools/abrmd/tss side... for now I'll test with another version and hopefully come back with more info. From a noob perspective, the error seems to be the same at [4], maybe I should try the same trick and see what happens.

This is just a hunch.  But I suspect that the code needs to be recompiled with your simulator (or real TPM). Some more information would be useful--does your TPM (real or virtual or simulated) have a SHA-512 PCR bank? Did you compile it on the same machine?  Or did you compile elsewhere or use a precompiled package or something like that? Dan From: Ricardo Araújo [mailto:ricardo@lsd.ufcg.edu.br]
