mcuboot bootloader update

Using following Setup:

IDE : VS Code (NRF connect plug-in)

Programmer : Stm32Cube programmer

St-link Debugger

OS: Zephyr 3.6

MCU: Stm32u5 series

Bootloader: mcuboot

I am looking for the zephyr's mcuboot bootloader upgrade support in STM32u5 toolchain via FOTA(Firmware Update Over the Air). As nrf provides a 2nd stage secure  bootloader mechanism in order to upgrade the mcuboot bootloader. Would the same process work in STM32?

Just to clarify it is the upgrade of the MCUboot (as and when the new updates come) not the application firmware that part is already working for us.

Hello @A Maq 

>>As nrf provides a 2nd stage secure  bootloader mechanism in order to upgrade the mcuboot bootloader. 

Not supported on STM32/Zephyr, STM32Cube might offer some tools and libraries that could be adapted, although this is not a primary feature.
