I’ve got a new Librem Mini and want to change the TPM Admin password from the factory default. When I start my Librem Mini boot, one of the first messages I get is that the TPM cannot be found.
Also, I followed the procedure in the docs for resetting the TPM: Boot > Options > TPM … > Reset TPM, but when prompted for the new TPM owner password and I enter and confirm it, I start getting a bunch of errors of the form “TPM_OpenClientCharDev: Could not open char device /dev/tpm0: No such file or directory” and “Error I/O error from TSC_PhysicalPresence” and “PhysicalENable returned ‘I/o error’ (-2147479547).”
I get a long list of these errors and then the operation asks me again for the TPM owner password and then hangs after I enter it.
Any thoughts? Thanks.
