    • Cortex-M33 without TrustZone

      Hi everybody,

      I'm using a Cortex-M33 with no Trustzone (STM32L5 with TZEN=0). However Ozone still shows me all register (e.g. PSP, MSP, PSPLIM, MSPLIM, ...) with _S (secure) and _NS (non-secure) suffix and I cannot modify them. Is this supposed to work or do I need to configure Ozone to not use the TrustZone as well?

      Best regards

    • Hello,

      Thank you for your inquiry.
      Sorry for the delay in response but this forum is not our official support channel so response times may vary.
      For more information see my signature.

      Regarding the trust zone issue. Which Ozone version are you using? Could you provide an example project that shows the behaviour?
      What would be the expected behaviour instead for you?

      Best regards,
      Nino
