Once the software is finalized, you must blow the SRKH (System Root Key Hash) into the OTP fuses. Warning: This is irreversible. If you lose the private key associated with this hash, you will "brick" any future boards produced. Step 4: Enabling "Secure Boot" Mode
Then generate the SRK table (hash + public keys):
