I have the NUCLEO-H753ZI example running on my board. All works fine without the security features. When I enable both the SFU_MPU_PROTECT_ENABLE and SFU_IWDG_PROTECT_ENABLE. I keep having a watchdog when it tries to execute the firmware. I commented...

I am new to SBSFU. I picked the NUCLEO-H753ZI project to try on a board with STM32H743. Everything seems to be running fine but ONLY when the SWAP_BANK is unchecked at startup. When it is checked before flashing, the board doesn't run as it was progr...

Found the example

Your example works fine as you are using UART. I am using instead of UART the USB DEVICE -> USB OTG HS. I put a macro everywhere you call the UART in your example to use the USB. Eg1.#ifdef USB_OTG_HS_ENABLEreturn MX_USB_DEVICE_Init();#elsereturn SFU...

I have started working on sbsfu and came across this post. What I found out is that you must CLEAN and build all 3 projects after you make any major changes like changing the keys. Hope that will help others that come against same issue.

My point is that we are relying that all new parts will be like you said and old parts would not have been changed. In summary, there is no solution when by any accident SWAP BANK is enabled before flashing the bootloader. The code in SFU_LL_SECU_Set...

Enabling the SWAP BANK in stm32cubeprogrammer was part of my test as I don't think every boards will have the default as unchecked. I just think it is a flaw currently with your example as it means we need to flash every boards twice to be 100% sure ...
