STM32CubeProg stm32h7xx Option Bytes User Configuration disappears if disabled by firmware

dariis · ‎2025-02-26

If on a STM32H747 the Cortex-M4 (BCM4 or BOOT_M4 Bit) is disabled by software, it is impossible to reactivate it with the STM32CubeProg v2.18.0 because the checkbox disappears in the user interface. But this happens only if you do a power cycle and reconnect to the target.
