Hello,
Can we run STM32CubeU5 TFM Application (UM2581) on U575 since it has not crypto hw like U585?
Thank you in advance!
Best Regards!

Hi @Gencay,
yes, crypto library will also work. TF-M needs the TrustZone isolation hardware, cryptography software implementation is a compromise that is acceptable.

Hello @JHOUD Thank you for your answer.
May I also ask which one does ST suggests? TF-M or X-CUBE-SBSFU?
Thank you in advance!
Best Regards.

Hi, I believe X-CUBE-SBSFU package is not really a TFM. But in STM32cubeU5 package there are TFM and SBSFU applications - both for U585, so you need to replace the cryptography with library, but both are basically TF-M. Pick whichever you like more. The one called SBSFU is trying to ease transition from non-TZ SBSFU, like for former STM32L4 users, while the other is cleaner TF-M, but the difference is mostly in the application, not in the loader or boot part.

Hello @Gencay;
I'm working on the same topic: porting TFM Application designed for STM32U585xx to STM32U575xx. Can you please list the steps you follow to get this?
Many thanks in advance
