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) technology.
However, I worked on ARM Cortex-33 based development board where i could configure the trust zone using various configuration tools.My question is how to add software level Trusted Execution Environment(TEE) trust zone for ARM Cortex-M3/M4/M7 processor?Is there any possible open source tool or software library available to do software level trustzone configuration for Cortex-M3/M4/M7 development board ?
Kindly let me know if anything available?
Thanks & Regards,
My point was that you need an Armv8-M processor to implement this.
