Help¶

Select this option to enable building a Secure firmware image for a platform that supports Trusted Execution. A Secure firmware image will execute in Secure state. It may allow the CPU to execute in Non-Secure (Normal) state. Therefore, a Secure firmware image shall be able to configure security attributions of CPU resources (memory areas, peripherals, interrupts, etc.) as well as to handle faults, related to security violations. It may optionally allow certain functions to be called from the Non-Secure (Normal) domain.

Direct dependencies¶

ARCH_HAS_TRUSTED_EXECUTION

(Includes any dependencies from ifs and menus.)

Defaults¶
