Trusted platform module


I want to add a TPM on my Jetson TX2.
Are they all compatible ?
I found that the brand is not important and i found these 4 different one :

  • ASUS TPM-M R2.0 14 pin
  • Asus TPM-L R2.0 20 pin
  • Asus Trusted Platform Module TPM/FW3.19 (20 pins)
  • Gigabyte TPM Module GC-TPM2.0 (20 pins)

How do I connect it to the jetson then ?

Hi antonin.baltayan,

We don’t have experience on TPM module with devkit, hope other developers could share information with you.


To get root of trust, you’d have to use the TPM in boot.

On Intel CPU PCs, this happens through the UEFI firmware, but because Jetson is ARM, and the boot manager / firmware of the Jetson does not establish a root of trust using TPM, then adding a TPM to a Jetson system seems largely meaningless. I mean, you can plug one in, and check a checkbox that it’s there, if you need to.

You may want to look into ARM TrustZone instead. See this thread for more:
