SFI firmware for stm32h533

Misterno08 · ‎2026-04-09

I’m working with an STM32H533 and would like to generate an SFI firmware using STM32CubeProgrammer.
Is it possible to use the SFI procedure without an HSM?
In particular, can the license file be generated without the card?

Hello @Misterno08 and welcome to the community;

As mentioned in this wiki "SFI STM32H5 How To Intro - stm32mcu" and which is guaranteed "isn't possible to use SFI without HSM". Because the HSM is used for key confidentiality and counting.

Thank you.
