12.2.2 Secure Boot Configuration
In addition to the Boot Configuration Packet content, the secure part of the boot sequence flow is controlled with data stored in the Secure Boot Configuration Packet.
The Secure Boot Configuration, stored in the Secure Boot Configuration
Packet in the OTP user area, contains all the information required to boot in Secure
mode:
- Secure Boot mode enable
- Authentication mode (AES-CMAC or RSA)
- Address of the regular packet containing the customer key wrapped with the PUF key
See Secure Boot Configuration Packet for a detailed description of the fields in the Secure Boot Configuration Packet.
During the prototyping phase, the OTPC Emulation mode can be used to test several configurations and the Secure Boot Mode without burning real OTP bits in the OTP matrix. See Boot Configuration Packet for more details.
