Re: CCTK 2.2.0 won't 'enable' TPM during CM OSD task sequence

Hi Keerthan.

Sorry for the late response, I've been offline.

After the 5th step, the status is 'deactivate'.

Re: CCTK 2.2.0 won't 'enable' TPM during CM OSD task sequence

Just a thought, have you tried an earlier version of BIOS? I've found it odd for some systems that an older version of bios works fine with CCTK, though I do not have much experience with the E6510.

Hi Mike,

Looks like some BIOS issue here again.

While rebooting, was it ensured to boot to operating system and not to BIOS setup screen ?

Yeah, the laptop I'm testing with initially had A09 installed, but the behavior was the same. Thanks!

Hi Shrinidhi. I'm unsure of your question exactly. I'm using the CCTK in a CM task sequence, after the set password, enable, reboot, activate, remove password, and reboot steps, I apply the OS.

Hi Mike,

The TPM enabling /activation through tools like CCTK/OMCI requires one to avoid going to BIOS setup screen, this is a BIOS requirement. So I asked it.

We shall get back on this.

Hi Mike,

I further checked on this issue.

I found that this issue can be resolved by clearing TPM.

TPM can be cleared by following steps

> Can you please go to BIOS setup screen->Security->'TPM Security' page

> Click Unlock

> Enter Setup password if Unlock button is active

> Check 'Clear' to the TPM; confirm the same in another dialog that pops up

> Click Exit to reboot

Once the above steps are done, try the TPM enablement steps through CCTK.

Hi Shrinidhi.

I have previously tried that in my troubleshooting.

It does not resolve the issue I am experiencing.

Thanks.

Hi Mike,

I further checked with BIOS. They also tested and confirmed that by clearing TPM, they are able to resolve the issue.

Please cross check and ensure that the TPM ownership has been taken before issuing command through CCTK.

RE: CCTK 2.2.0 won't 'enable' TPM during CM OSD task sequence

My process works in PE during OSD, but if I am re-purposing a laptop where the TPM had been deactivated (but still enabled), the TPM does not activate.  On the 6430, if I manually clear the TPM in the BIOS that seems to work.  How can I have CCTK activate a TPM chip where it was already enabled?
