Hi,
i am using trousers with a tpm-emulator (http://tpm-emulator.berlios.de/)
on linux (ubuntu 12.10 and debian 6.0.7).
My problem is that tpm_takeownership and all other important commands just
deliver a "internal software error:
tpm_selftest and tpm_version (seem to) work fine:
tpm_version:
TPM 1.2 Version Info:
Chip Version: 1.2.0.7
Spec Level: 2
Errata Revision: 1
TPM Vendor ID: ETHZ
TPM Version: 01010000
Manufacturer Info: 4554485a
tpm_selftest:
TPM Test Results: 53756363 65737300
But when i try to take ownership of my tpm i get an internal software error:
sudo ./tpm_takeownership -l debug -y -z
Tspi_Context_Create success
Tspi_Context_Connect success
Tspi_Context_GetTpmObject success
Tspi_GetPolicyObject success
Tspi_Policy_SetSecret success
Tspi_Context_CreateObject success
Tspi_GetPolicyObject success
Tspi_Policy_SetSecret success
Tspi_TPM_TakeOwnership failed: 0x00002004 - layer=tcs, code=0004 (4),
Internal software error
Tspi_Context_CloseObject success
Tspi_Context_FreeMemory success
Tspi_Context_Close success
As well as for tpm_getpubeek:
sudo ./tpm_getpubek -l debugTspi_Context_Create success
Tspi_Context_Connect success
Tspi_Context_GetTpmObject success
Tspi_TPM_GetPubEndorsementKey failed: 0x00002004 - layer=tcs, code=0004
(4), Internal software error
Tspi_Context_FreeMemory success
Tspi_Context_Close success
!! The same problem also appears when i use the HW-tpm; but as i target to
use a tpm-emulator i did not test as much with it.
