1. Welcome

Welcome to Infineon TPM 1.2 Test- and FieldUpgrade-Tool "TPM12TST". 

The TPM 1.2 Test- and FieldUpgrade-Tool "TPM12TST" is intended to be used to
create an Endorsement-Keypair (EKP) on-chip, to perform a short test and to upgrade the
Firmware of the Infineon Technologies TPM SLB9635TT1.2 from the Version 242.66 (F2.42)
to the Version 242.68 (F2.44).


1.1 Prerequisites

PC compatible platforms, MS-DOS 6.0 and later, running from 1,44MB Floppy Disk,
HDD or bootable USB-Stick.


1.2 Installation

Unzip TPM_F244.ZIP into a single folder on a HDD, where MS-DOS is installed
or onto a bootable MS-DOS Floppy Disk or USB-Stick.


1.3 Operation

TPM12TST is operated as follows:

Call: TPM12TST
Calling without parameter starts the EKP generation, testing and FieldUpgrade process.
First the TPM is checked wether it is enabled and activated, if not, it will be
enabled and activated if PhysicalPresence is not locked by the Platform BIOS. If this
was successfull a reboot is required to complete this step. If not, this step must be
done manually via the appropriate BIOS Setup Page.
Next the on-chip generation of an EKP is started, if already present an according
message is displayed.
Thereafter, the TPM-built-in Selftest is performed and the current version info
is read out and displayed.
Finally, if the current FW Version can be upgraded, the Fieldupgrade-Process is
performed.


Options in TPM12TST.CFG:
[IO_Address]
IO_BASE = 0x4700
CFG_BASE = 0x4E

IO_BASE is the Runtime address for the TPM which is configured by the
platform Bios in the PC Chipset.

CFG_BASE is the Config address for the TPM which is configured by the
platform Bios in the PC Chipset.

Please consider that the TPM12TST.EXE does not configure the PC chipset and
therefore relys on a proper setting of the PCI to LPC bridge.
