Hello

I just d/l the latest releases of trousers + tpm-tools. My kernel is 2.6.37.6.

What works is:

I modprobe the tpm_tis module:
tpm_tis 00:0c: 1.2 TPM (device-id 0x1001, rev-id 2)

# ps ax | grep tcsd
15844 pts/0    S      0:00 tcsd -f

# tpm_version

  TPM 1.2 Version Info:
  Chip Version:        1.2.2.10
  Spec Level:          0
  Errata Revision:     0
  TPM Vendor ID:       BRCM
  TPM Version:         01010000
  Manufacturer Info:   4252434d

And what doesn't work:

# tpm_takeownership -y -z
Tspi_TPM_TakeOwnership failed: 0x00000023 - layer=tpm, code=0023 (35), No EK

So I manage to create an Endorsment Key:

# tpm_createek             (hangs for 4-5 second, then:)
TCSD TDDL ERROR: read from device /dev/tpm0 failed: Timer expired
Tspi_TPM_CreateEndorsementKey failed: 0x00001087 - layer=tddl, code=0087 (135), 
I/O error

So, how can I manage to work with this TPM?

Strange fact:
The tpm command launched after the tpm_createek fails once:

# tpm_createek 
TCSD TDDL ERROR: read from device /dev/tpm0 failed: Timer expired
Tspi_TPM_CreateEndorsementKey failed: 0x00001087 - layer=tddl, code=0087 (135), 
I/O error
# tpm_version 
TCSD TDDL ERROR: read from device /dev/tpm0 failed: Timer expired
# tpm_version 
  TPM 1.2 Version Info:
  Chip Version:        1.2.2.10
  Spec Level:          0
  Errata Revision:     0
  TPM Vendor ID:       BRCM
  TPM Version:         01010000
  Manufacturer Info:   4252434d

thanks for any help
