[MinnowBoard] PTT TPM2 functional?

[Wu, Mike]

Hi, Philip,

For X64 firmware, to support PTT/fTPM, you will need to rebuild the firmware, please read the firmware release notes "How to enable fTPM feature"

Subject: [MinnowBoard] PTT TPM2 functional?

Hello,

There was a thread some time back with someone asking about the new PTT / TPM2 support in the Minnowboard Max 0.80 firmware:

http://minnowboard.57273.x6.nabble.com/MinnowBoard-PTT-support-td1701.html#a1704

I hadn't had a chance to test it till now but my testing didn't get far.
I'm working on a Minnobwoard Max B3 platform with firmware identified as "MNW2MAX1.X64.0082.R02.1507271125" which I believe is the latest.

I've gone into the firmware config interface, found the "security configuration" section and enabled PTT as well as "Measured Boot".
Secure boot is disabled. My test program is a simple UEFI executable that just gets a handle by way of the EFI_TCG2_PROTOCOL_GUID. I get no handles back however. I've tested the same code on a haswell NUC
(D54250WYK) that has PTT and it at least returns a handle that I can use to make calls to GetCapabilities.

Has anyone else tested this / got this to work? There are some resources out there that had me thinking it should:

https://firmware.intel.com/blog/security-technologies-and-minnowboard-max

so I'm a bit worried that my boards (both of them) are defective, or that I'm defective and just can't find the right config to enable it.

TIA,
Philip
