Success!

Geschrieben von Paul Kissinger am
Hello and welcome!

I´m really proud to introduce the new way to get your LetsTrust-TPM working with your Raspberry Pi!

Till the next Stretch update from the RasPi Foundation the way will be:

Step one:
Open a (whatever) term on your Pi.

Step two:
run a "sudo rpi-upgrade"

Step three:
open the /boot/config.txt with "sudo nano /boot/config.txt"
and activate SPI with uncomment
"dtparam=spi=on"
and load the TPM device tree overlay with
"dtoverlay=tpm-slb9670"

Step four:
plug your LetsTrust-TPM on the right position and reboot your Raspberry Pi

Step fife:
Open a (whatever) term on your Pi and type "ls /dev/tpm0" and
/dev/tpm0 will appear in yellow letters!

Step six:
Be happy about your success!

Grateful thank to a friend of mine an ex colleague: Peter Hüwe.
He find this smart solution [1] for the Pull Request issues [2].

Thank you to Phil Elwell to evaluate, identify problems and finally merged the PR [3]


By for now!

Paul

sudo ./eltt2 -h

Hallo zusammen,

Monate ohne neue Blog-Postings, bitte entschuldigt, ich hatte einfach zu viel zu tun./

So, jetzt habe ich das letzte Raspbian-Image "Stretch" mit dem TPM-SPI-Treiber gepatcht, dieses findest du auf diesem LINK..

In diesem Image ist das eltt2-Tool NICHT vorkompiliert.

Um dies zu ändern:

git clone https://github.com/Infineon/eltt2.git
cd eltt2
make
sudo ./eltt2 -g
sudo ./eltt2 -h


Das wars für heute!

Paul
