These security states These TrustZone domains are set through TZASC registers, which are configured by the Arm Trusted Firmware (ATF) on the device. In systems with virtualization, each of the virtualized software environments (Virtual Machines, or VMs) is isolated from each other, and there is no direct interaction between VMs other than going … ARM’s TrustZone introduces a new mode: the secure monitor mode. The Cortex-M33 processor inside the nRF9160 uses the new ARMv8-M architecture which offers a new feature called „ARM TrustZone„. Does this technology allow doing the above -- sealing a private key under a code hash? With write-back cache, you'll see old/invalid data! The SDK is based on the OP-TEE project which follows GlobalPlatform TEE specifications and provides ergonomic APIs. As per ARM documentation , it gives that a process can run in Secure / Non-Secure World. SYStem.MemAccess DAP DAP-Access to ARM internal bus (APB/AHB/AXI) Caution: Cache invisible!
