TPM control

[Whenow]

I got a new computer (8GB RAM, 64-bit, AMD Ryzen 5 3550h) & managed to install Fedora 30 on it. I want to gain control of the TPM and began following https://paolozaino.wordpress.com/2017/03/18/configure-and-use-your-tpm-modul... for guidance. TPM does show up in the BIOS as enabled but I can't set anything about it.

# dmesg | grep -i tpm

gives

[    0.000000] efi:  ACPI=0x8f7fe000  ACPI 2.0=0x8f7fe014  ESRT=0x8e60b998  SMBIOS=0x8e607000  SMBIOS 3.0=0x8e605000  MEMATTR=0x7e2d4018  TPMEventLog=0x7516e018

# systemctl status tcsd

gives

No idea what this really means.
whereis tcsd
gives
tcsd: /usr/sbin/tcsd /etc/tcsd.conf /usr/share/man/man8/tcsd.8.gz
so I have tcsd, it just isn't talking with the TPM, apparently.

# systemctl enable tcsd

gives no response, apparently succeeds.

# tpm_version

gives

Tspi_Context_Connect failed: 0x00003011 - layer=tsp, code=0011 (17), Communication failure
This is my first rodeo with TPM and I'm trying to gain control over it so I can reinstall an OS and boot live disks and such and not be banned from doing so by my computer. What's wrong with TPM & how do I gain control over it?
Thanks.

The TPM is not going to stop you from doing any of that.

What does "ls -l /dev/tpm*" show?

Samuel et al,
The 2 tpm devices are there. I actually figured this out on my own. Chalk it up to my own ignorance and my lack of clear guidance from Internet on how to properly control TPM. Thanks for your attention.
