1 The Cortex-M series microcontrollers based on the ARMv8-M architecture (Cortex-M33 and Cortex-M23) introduce TrustZone technology. TrustZone enables two security domains within a single processor, partitioning the execution space into secure and non-secure areas. This enhances security by achieving complete isolation between trusted software running on the secure side and untrusted software running on the … Read more
With the TrustZone technology supported by the ARMv8-M architecture, critical security firmware and private programs (such as secure boot, firmware updates, and keys) can be isolated from the rest of the applications, significantly reducing the chances of being attacked and increasing the security of embedded systems. SEGGER’s embOS currently supports ARMv8-M TrustZone, making embOS a … Read more
Source | STM32 The STM32L5 is based on the Cortex-M33 core, which is built on the ARMV8-M architecture and features TrustZone security technology, effectively isolating the secure and non-secure areas from the core to the entire chip system. In terms of debugging port protection, the combination of TrustZone and RDP (Read Protection) can also achieve … Read more
October 19, 2004, is a special day that may not mean much to most people. However, if you are part of the embedded community, you know that the microcontroller (MCU) industry underwent a revolutionary change on this day. ARM® released the first Cortex®-M processor, bringing the advantages of a general-purpose architecture to the microcontroller market. … Read more
In the previous article, we unveiled the new members of the Cortex-M family, the two pioneers of the ARMv8-M architecture—Cortex-M23 inherited from Cortex-M0/M0+ and Cortex-M33 inherited from Cortex-M3/M4. We understood the changes in the instruction set, pipeline, and peripherals, but what about the Security Extension (安全扩展) or TrustZone for ARMv8-M, which is the highlight of … Read more
