Hi ST team,
I am trying to develop a secure bootloader and firmware update solution for STM32H735 MCU. I was looking at ST's implementations, SBSFU legacy and SBSFU by MCUboot. Could you give me some guidance, which would be the better choice to start from and port to my chip? I saw that SBSFU by MCUboot is targeted only to STM32H7S, and not STM32H7, so I assume if I want to go with MCUBoot, most of the code built on top of MCUBoot by ST is not going to be usable for me, is that correct?
I need these features for the bootloader:
- immutable bootloader implementation
- application authentication (using signature verification)
- secure application update
- anti-rollback protection
- A/B update scheme to provide a fallback option
- Preferably support for TCP communication for image download (or allowing easy integration for it)
Thank you for your help.
