TrustZone Enable afterwards

Cati · ‎2025-05-31

Hi All,

I wrote my code in STM32IDE without using TrustZone. Now I need to enable it, however this does not appear to be available in STM32IDE once the project has been created. Am I correct, or is it possible to enable TrustZone for an existing project in STM32IDE afterwards?

Best Regards,

Cati

Hello @Cati

Once the project has been created throw the STM32CubeMX without trust zone enabled throw the GUI, you can't enable the trust zone. So, for that you need to enable the trust zone before generating the project.
