Output of tpm_version from tpm-tools debian 11.2 `TPM 1.2 Version Info:` `Chip Version: 1.2.13.12` `Spec Level: 2` `Errata Revision: 3` `TPM Vendor ID: STM` `Vendor Specific data: 50` `TPM Version:...
I disassembled my W530 to manually reset the TPM chip ( ST19NP18 - U39 on motherboard). This does not work for me as I just get a blank screen and...

With IBM's TPM 2.0 TSS, I get the following: `ln -s /dev/tpm0 /dev/tpmrm0` root@debian:/usr/local/bin# tss1startup -v TSS_Execute12: Command 00000099 marshal TSS_Execute12_valist: Step 1: initialization TSS_Execute12_valist: Step 6: calculate HMACs TSS_Execute12_valist:...
Made some progress thanks to this site: https://www.electronicayciencia.com/2020/09/practicas-tpm-virtual.html. Booted into a live environment Debian 11.2 and installed tpm-tools. Now before running tcsd -f, we manually write following commands to /dev/tpm0...
This method isn't working anymore and I can not replicate correct behavior. `python3 -c 'f=open("/dev/tpm0", "r+b", buffering=0); f.write(b"\x00\xC1\x00\x00\x00\x0C\x40\x00\x00\x0A\x00\x20" ); print(f.readall())'` **TMP_PhysicalPresence -> CMD_ENABLE** returns `\x00\xc4\x00\x00\x00\n\x00\x00\x00\x03` and we expect `\x00\xc4\x00\x00\x00\n\x00\x00\x00\x00`
Probably I have set **TPM_PHYSICAL_PRESENCE_LIFETIME_LOCK** to TRUE which explains why I'm getting TPM_BAD_PARAMETER when trying to change permanent flags. Either by sending: `tpm physicalpresence -x 0x0080h (heads)` `tpm_setpresence --set-lifetime-lock (trousers)`...
@tlaurion thanks for your screenshot. Everything is the same with me except "Read Pubek". We also have volatile flags we can check running `tpm getcapability -cap 4 -scap 109` But...
