SC000/Cortex-M0 are based on Armv6-M architecture, so does not support TrustZone. TrustZone is available in Armv8-M and the processors built with TrustZone Technology can be found here:

TrustZone for Cortex-M was added in Armv8-M architecture. The processors you mention at Armv7-M. See the following links for more information:

Hello Team,
I'm working on a project using ARM Cortex-M3/M4/M7 development board where i need to configure the Trusted Execution Environment(TEE), but i could not able to do this.After that, i found that these architectures are not having (ARM TrustZone…
Hi,
I am using CortexM23 with TrustZone enabled I wanted to write a secure program, but I failed. These are what I did:
By the way, I am using uvision Keil 5.
Hello,
I am reading the AMBA 5 CHI Architecture Specification and in the overview it says:
"ARM TrustZone support on a transaction-by-transaction basis."
but I cannot find more information about TrustZone
I would expect some TrustZone IP, similar…
I'm facing an issue that makes me very confused: I would like to enable TZASC on N1SDP. However, I found that Trusted-Firmware does not include such code to configure secure memory in the file n1sdp_security.c (https://github.com/ARM-software…
n1sdp_security.c
Is there any example TrustZone application for Cortex-M85? I use MPS3 FPGA image (AN555, SSE-310) and KEIL IDE. The IDE does not provide any example TrustZone Project. I am having difficulty creating from scratch (Configuring NS and S). If anyone has…
I would like to know, Is there any document section for ARM TrustZone explaining the TrustZone extension
Kindly support with Weblinks
Thanks & Regards

Hi all,it would be possible to run two different RTOS kernels on a single core (Cortex-M33) using Trustzone?
For example, let's suppose I want two full RTOS instances (e.g. FreeRTOS), one running in secure zone and other running in non secure zone.
TrustZone technology for Arm Cortex-M processors enables robust levels of protection at all cost points for IoT devices. The technology reduces the potential for attack by isolating the critical security firmware, assets and private information from the…
