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…
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.
I would like to know, Is there any document section for ARM TrustZone explaining the TrustZone extension
Kindly support with Weblinks
Thanks & Regards

Hi,
I'm working on bare metal firmware using Cortex M55. Trustzone and use of cmse macros are enabled.
Both secure world and non secure world are created and built.
We want to call a secure service from non secure world. So for that we create a cmse_ns_entry…
I would like to know the Difference between the OP-TEE and ARM TrustZone
TrustZone has been successfully securing media pipelines on Arm-based devices for over a decade. During this time the requirements of these devices have grown significantly with bit rates, resolution, frame rates, picture quality, and user interface innovation…
