CONFIG_INIT_ARCH_HW_AT_BOOT¶
Initialize internal architecture state at boot
Type: bool
Help¶
This option instructs Zephyr to force the initialization
of the internal architectural state (for example ARCH-level
HW registers and system control blocks) during boot to
the reset values as specified by the corresponding
architecture manual. The option is useful when the Zephyr
firmware image is chain-loaded, for example, by a debugger
or a bootloader, and we need to guarantee that the internal
states of the architecture core blocks are restored to the
reset values (as specified by the architecture).
Note: the functionality is architecture-specific. For the
implementation details refer to each architecture where
this feature is supported.
Defaults¶
No defaults. Implicitly defaults to n.
