Arm® Automotive Solutions

The Arm Automotive Solutions Software Reference Stack is composed of multiple Open Source components which together demonstrate use cases for the automotive sector, including:

• The Runtime Security Engine (RSE) running an instance of Trusted Firmware-M, which offers boot, cryptography, and secure storage services.

• The Safety Island subsystem, running three instances of the Zephyr real-time operating system (RTOS).

• The firmware for the Primary Compute, using Trusted Firmware-A, U-Boot, OP-TEE and Trusted Services. These are configured to be aligned with Arm SystemReady Devicetree (formerly named Arm SystemReady IR).

The remaining software in the Primary Compute subsystem, based on the EWAOL distribution, is available in two main architectures: baremetal and virtualization.
