Using Trusted Firmware-M on STM32U5 / STM32L5, building my own non-secure application and interact with TFM.

[ZKRAC.1]

Hello,

I want to use the security features included in the TFM in my application, I have followed UM2851, now,I have a better understanding for TFM and I succeed to implement it in STM32U585, to go further I want ot implement my own non-secure application and to interact and use secure services via PSA APIs, I have searched all the web for that, but I didn't find a hint.

Any explanation or a hint, please !

Thank you.

Regards,

ZK.

Hello @ZKRAC.1​ ,

I advise you to review the TFM examples available under STM32CubeU5 MCU package:

STM32Cube_FW_U5_Vx.x.x\Projects\B-U585I-IOT02A\Applications\TFM

The examples can be configured according to your need.

Have a look at theses presentations:

• TFM pointers
• TFM TFM flash memory footprint

I hope this helps you!

Hi @Imen DAHMEN​ ​ ,

Thank you for your answer, I'm using the complete TFM from the Cube Firmware U5, what I don't understand is how to use the non-secure applications and PSA APIs,and how I can integrate my own non-secure application. I just started with TFM, I have read the UM2851 and the docs you have mentioned above.

Thank you.

Regards,

ZK.
