Enabling TPM on OptiPlex
Hello,
I need some help with enabling TPM on OptiPlex 5050 systems running Ubuntu. I have enabled TPM from the BIOS, but when I check from the terminal it shows no TPM chip found.
PC1:~$ dmesg | grep -i TPM
[ 0.000000] ACPI: TPM2 0x00000000DAE694A8 000034 (v03 DELL CBX3 00000001 AMI 00000000)
[ 0.000000] ACPI: Reserving TPM2 table memory at [mem 0xdae694a8-0xdae694db]
[ 1.354556] tpm_tis: probe of MSFT0101:00 failed with error -1
[ 1.386756] ima: No TPM chip found, activating TPM-bypass! (rc=-19)
Some of our internal applications requires TPM2.0, and we are testing it; but we seem to face issues with this particular model.
Would be grateful if anyone has any ideas to resolve this.
Thanks!
Ever figure anything out? I'm seeing the same problem on Precision 5520:
Dell Inc. Precision 5520/0R6JFH, BIOS 1.31.0 11/10/2022Running Arch Linux with kernel 6.1.12-arch1-1
Have the tpm working fine on the same kernel on i5-12500 and an non Dell motherboard.

Was able to resolve this by disabled Trusted Execution/TXT and clear the TPM in the BIOS.
