Product Change Notification - LetsTrust-TPM

Posted by Paul Kissinger on
Hello to everyone,

I have a product change notification for you today! (PCN)

LetsTrust-TPM gets a new chip. The usual Infineon quality remains and from now on the SLB9672 FW15.23 will be used!

What will change? Basically nothing for the user, the config.txt change remains as before, the devicetree overlay is loaded via -> dtoverlay=tpm-slb9670. Because the SLB9672 is 100% driver compatible with the old overlay (yay!)

We were also able to retain the layout, because the SLB9672, like the SLB9670, follows the specifications of the TCG (Trusted Computing Group) regarding the pinout and the package.

Only the TCG Spec version changes, here we have to take what we get from Infineon. The latest firmware version is based on the specification revision Rev.:1.59 and no longer on Rev.:1.38 as before (higher is better).

This change is effective as of Monday, May 13th. All LetsTrust-TPMs ordered from then on will be on the latest possible version!

Bye for now,

Paul
