Subject: Re: [BUG] Nuvoton NCPT650 TPM 2.0 mode not working

Hi again,
after some experiments I finally found a solution...
There seems to be a bug in TPM2.0 firmware version (1.3.1.0) included in Lenovos
UEFI image but they do not provide an update.
I have extracted the firmware version 1.3.2.8 from Dell's XPS15 TPM2.0 firmware
update and used this to replace the firmware in my Lenovo UEFI image.
After flashing this version via UEFI Setup the TPM2.0 gets detected and now is
fully working. WTF.
For anyone having the same problem: binwalk, uefi-firmware-parser, uefipatch and
flashrom are your friends ;-)
Best regards
Michael
