CONFIG_STM32H7_BOOT_CM7_CM4GATED

Boot CM7. CM4 boot gated

Type: bool

Help

Cortex-M4 boot is gated using Flash option bytes Cortex-M7 and Cortex-M4 running from the flash (each from a bank) Cortex-M7 boots , performs the System configuration then enable the Cortex-M4 boot using RCC. This mode requires option byte setting update (BCM4 unchecked)
