TrustZone option removed from ST Cube IDE for STM32H7?

[NickO]

In previous iterations of ST Cube IDE, the project creation wizzard included a tick box to create a project based on TrustZone. This option seems to have been removed. I am using an STM32H755.

Is there another way in which TrustZone based projects should now be created, and if so, could someone direct me to the revised documentation? I searched but maybe I am missing something?

Hello @NickO 

First let me thank you for reporting.

I'm currently investigating this issue. I will get back to you asap.

Hello again @NickO 

By checking the RM0433 Rev 8 (Reference manual STM32H742, STM32H743/753 and STM32H750 V):there is no Bit  TZEN: Global TrustZone security enable and that's why there is no tick box to create a project based on TrustZone which means STM32CubeMX is behaving correctly.

On the other hand for example STM32U575 does support a TRUSTZONE and if you check RM0456 Rev 6

you find this 

so there is a tick box to create a project based on TrustZone.

Hello

The STM32H755 does support trust zone however?

Correction - I think I can see the issue. The 755 has RSS, but not TrustZone. I am confusing STM32 Trust with TrustZone?
