I am using Arm Development Studio IDE to remotely debug an application with gdbserver, when I launch the application I have this message: thread 3700 #1 stopped (reserved) and it doesn't let me debug step by step.
How can I remove the reserved restriction…
A technical report on ARM TrustZone based on the development of T6:
Hi, When confidential computing is exploding with Intel-SGX, I am supposing AWS is also on the topic with NITRO I am looking for similar scheme on ARM and more on ARM-8A, Aarch64 for RPI-4 like platform or similar. The requirement is an easy template…
The TZC-400 TrustZone module now has only up to ACE-lite interface. If I use CMN which is CHI and a memory controller which is also CHI, how can I enable TrustZone?
Another question that I see come up once in a while.
Both the Cortex-M33 and the Cortex-M23 support TrustZone for ARMv8-M.
Cortex-M23 is the smallest lowest power TrustZone Cortex processor from ARM.
Cortex-M33 is a general purpose TrustZone processor…
And you can read more about this in my colleague robcoombs blog TrustZone extends to microcontrollers and TrustZone CryptoCell for all ARM platforms
While both of them are called TrustZone and at high level the concepts are similar, at low level of the architecture there are many differences between TrustZone on Cortex-M23/M33 and Cortex-A. The following website summarized the key differences:
