Hi list,
I saw a message regarding the infineon SLB9635TT1.2 in January where
tpm_takeownership doesn't work.
I am in the same situation with probably the same chip, or a slightly newer
firmware version:
$ 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
$ sudo tpm_createek
Tspi_TPM_CreateEndorsementKey failed: 0x00000008 - layer=tpm, code=0008
(8), The TPM target command has been disabled
$ sudo tpm_version

Any ideas what I'm doing wrong?
