Enabling TPM on OptiPlex


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.
