Secure Boot on STM32C031 Family

[ouss_mans]

Hello ST Community,

Can we apply Secure Boot on the STM32C031 family? I didn't find anything on the documentation. If not, what are the product series where we can apply Secure Boot?

Thank you.

Hi @ouss_mans 

The STM32C0 family is not listed among the series that support SBSFU. I will check internally if any implementation is planned !!!

Product Series Supporting SBSFU 

1. STM32L4 Series
2. STM32F4 Series
3. STM32F7 Series
4. STM32G0 Series
5. STM32G4 Series
6. STM32H7 Series
7. STM32L0 Series
8. STM32L1 Series
9. STM32WB Series
10. STM32WL Series (example provided within STM32CubeWL firmware package)^{[Security:SBSFU legacy - stm32mcu]}.

Generally the Elliptic Curve and hashing / signing functions are large and slow.

Can they be used on CM0(+) parts, sure but you're apt to get headaches from the overheads.

A 16KB part is rather challenging, the HAL and float library are going to make quite a dent before you've done anything.
