[TrouSerS-users] Can't take ownership, unknown error

Hi All,

I trying to use the Atmel AT97SC3205T I2C TPM chip with trousers and
tpm-tools. Here are some version numbers

Linux 3.13
trousers 0.3.10
tpm-tools 1.3.8

I am running into the same problem Florian, who wrote the original post,
had. I followed the instructions in that thread from Kent, and enabled
debugging for the trousers build. The output from trousers and
tpm_takeownership are below.

Would someone take a look and see what might be wrong with my system?

Thank you.

Harry

Thanks for advice. I ran the tpm_createek, but it failed with this output

Regarding ownership, I am doing this during initial board bring-up, so I
can't image the ownership been taken already. I have gotten the this error
every time I run tpm_takeownership.

Usually if you can't take ownership, it is because you need ask the TPM to
create an ek, or ownership was already taken.

Regarding ownership, I am doing this during initial board bring-up, so I
can't image the ownership been taken already. I have gotten the this error
every time I run tpm_takeownership.

Usually if you can't take ownership, it is because you need ask the TPM
to create an ek, or ownership was already taken.

Hi All,
I trying to use the Atmel AT97SC3205T I2C TPM chip with trousers and
tpm-tools. Here are some version numbers
Linux 3.13
trousers 0.3.10
tpm-tools 1.3.8
I am running into the same problem Florian, who wrote the original
post, had. I followed the instructions in that thread from Kent, and
enabled debugging for the trousers build. The output from trousers and
tpm_takeownership are below.
Would someone take a look and see what might be wrong with my system?
Thank you.
Harry

No, I have not come across this yet. Can you provide the subject name of
that discussion thread?

I see this problem was discussed before for a real HW TPM.
I am running SW TPM and TSS stack on top of it. Now I am trying to
take ownership, after clearing it,
tpm_clear -f
Tspi_TPM_ClearOwner failed: 0x00000007 - layer=tpm, code=0007 (7), TPM
is disabled
$ tpm_takeownership -zy
Tspi_TPM_TakeOwnership failed: 0x00000007 - layer=tpm, code=0007 (7),
TPM is disabled
$ ./getcapability -cap 4 -scap 0108

Any suggestions what command I need to run next to solve this problem?

Regarding ownership, I am doing this during initial board bring-up, so
I can't image the ownership been taken already. I have gotten the this
error every time I run tpm_takeownership.
Harry
On Fri, Mar 27, 2015 at 6:32 PM, David Challener <

Usually if you can't take ownership, it is because you need ask the
TPM to create an ek, or ownership was already taken.

Hi All,
I trying to use the Atmel AT97SC3205T I2C TPM chip with trousers and
tpm-tools. Here are some version numbers
Linux 3.13
trousers 0.3.10
tpm-tools 1.3.8
I am running into the same problem Florian, who wrote the original
post, had. I followed the instructions in that thread from Kent, and
enabled debugging for the trousers build. The output from trousers and
tpm_takeownership are below.
Would someone take a look and see what might be wrong with my system?
Thank you.
Harry

Take a look at the main spec. The first Action of TPM_ReadPubek may be
the source of your error.

I encourage everyone, especially people new to this technology, to begin
debugging with the software TPM. It has extensive tracing to help debug
problems. OTOH, all crypto hardware by design hides its internals.
