Bootloader in STM32H753

[ranganath_b_rangaramu]

Hi Team,

 I am trying to add a Secondary/custom bootloader in SBSFU. But not able to figure it out how to do it. I changed memory for active slot area and used the same area for custom bootloader in both linker file of both SBSFU and custom bootloader application. But does not work as expected. Can you please guide me through this? 

I need to add a Custom bootloader and trigger user application from it. What are the modification that I need to do for this. I am using STM32H753 board.

Hi @Jocelyn RICARD ,

          I am able to build a custom bootloader and this image is verified in SBSFU. 

Now i want to add verification of user application in custom bootloader. How we can achieve this?

Hello @ranganath_b_rangaramu ,

The verification of the user application is the SBSFU task.

The custom loader task is only to download and flash the encrypted/signed application.

Best regards
