Question

STM32F769I-DISCO and MCUboot

I am building MCUboot using Zephyr for some of the STM32 MCUs like `stm32f769i_disco`. 
MCUboot using zephyr client tested and working fine with the board `stm32f769i_disco`. 

Now I am trying to use that MCUboot with the User application I have written in STM32CubeIDE but the application hangs or nothing happens. The Bootloader output looks fine, but nothing prints from the application. What configuration steps am I missing on user application side or MCUboot side?

Using the standard addresses:
MCUboot: 0x08000000

User Application: 0x08040000
VECT_TAB_OFFSET: 0x40000

I have attached my user application project as a zip file.

    The "Image verified" message means only that the app image looks valid (signed, correct CRC or whatever). But in fact the app may be broken. Are you sure it works at all?

    Yes, I used the application as standalone flashed at 0x08040000, it works, normally. I know there needs to be some config done to use it with MCUboot, not just sure what using STM32CubeIDE.
