I have system with
TPM 1.2 installed on it. Currently, I'm using tpm-tools to initialize this TPM. With the command
tpm_extendpcr -p 23 tpm-pcr.key
I can write a value into a PCR which works fine.
After rebooting the system, the corresponding PCR register is empty again. Is there a way that can help me to permanently write a value into a PCR register?
