1.Does Thor support fTPM?

2.can fTPM over OPTEE without fused can be used (on Thor)?

Related info:

  1. in the THOR fuse doc.

    FUSE_BOOT_SECURITY_INFO Boot Security Info
    Bits interpreted by boot software with
    following mapping:
    Bit [3]: Secure boot encryption enable
    Bit [5]: Revocation policy enable
    Bit [9]: OEM Fuse Key Load
    Bit [10]: Disable skip OEM authentication
    for diagnostic boot
    Bit [13]: OEM fTPM Feature enable
    Bits not listed are reserved

=> bit13 available for fTPM feature on THOR

  1. in Jetson Linux Developer guide / Security / Firmware TPM

    “Applies to the Jetson AGX Orin series, Jetson Orin NX series, and Jetson Orin Nano series.”
    => no THOR is mentioned.

hello noah538,

it should be documentation erroneous, JP-7.1/r38.4 support with Thor series only.
besides.. Thor does support fTPM, I can see below from Thor’s bootloader logs.

[0001.934] I> Task: MB2 Params integrity check
[0001.939] I> Task: Measured Boot init 
[0001.942] I> Task: fTPM silicon identity init 
[0001.946] I> fTPM is not enabled.

Thanks, I will give it a try.
