8.10.2 Secure Boot
During the boot process, secure boot will check for an embedded signature stored in the module. If
the signature matches against a database of signature in Secure Boot, the module is allowed to
execute the actual application (jump to application). Secure Boot functions similarly to a security
gate.
The functions of the secure bootloader:
1. Checks for the any new firmware available in the external flash to upgrade the device.
2. It validates the signature of new image available in external flash.
