Hi
Maybe some answer is in

ARMmbed/mbed-os/blob/master/targets/TARGET_STM/TARGET_STM32H7/README.md#dual-mode-configuration

# STM32H7 family

[st.com STM32H7 family page](https://www.st.com/en/microcontrollers-microprocessors/stm32h7-series.html)

[GitHub STM32CubeH7 FW](https://github.com/STMicroelectronics/STM32CubeH7)

# Single core STM32

## STM32H743xx

STM32H743ZI devices are based on the high-performance Arm Cortex-M7 32-bit RISC core operating at up to 480 MHz.
