HPE EL300 Converged Edge Systems that are configured with a Trusted Platform Module (TPM)now support an updated version of TPM firmware. This firmware applies to the "HPE Trusted Platform Module 2.0 for HPE EL300 Converged Edge system," and is applicable to both TPM 1.2 and 2.0 modes of operation. The TPM firmware can only be upgraded. It cannot be flashed with the same version or downgraded to a prior version. TPM usage by OS/applications using the TPM should be suspended before updating the TPM FW and resumed after updating the TPM FW. This revision of Trusted Platform Module (TPM) firmware includes the latest update from ST Microelectronics to address CVE-2019-16863. Updating the EL300 TPM FW changes TPM PCR values that OS/applications using TPM may examine, and can disrupt access to encrypted disks/information. Please check the OS/application manuals for details. Version 73.20 is the latest recommended upgrade, and more details are provided below.
